Chemical reactions
Compare physical and chemical changes
Matter is made of very small particles called atoms. Atoms can be linked together by chemical bonds. When two or more atoms link together, they form a molecule. In a chemical change, the chemical bonds in the molecules break. The atoms then link together to form different molecules. The types of molecules in matter before and after a chemical change are always different. Some chemical changes are caused by heating or cooling. For example, burning a piece of paper is a chemical change caused by heating. As paper burns, paper molecules react with oxygen molecules in the air. This reaction breaks the chemical bonds in the molecules. The atoms then link together in a different way to form different molecules. For example, carbon dioxide molecules are formed when paper burns. In a physical change, chemical bonds do not break. The types of molecules in matter before and after a physical change are always the same. A change of state is a type of physical change. Changes of state can be caused by heating or cooling. For example, water vaporizing is a physical change that can be caused by heating. Liquid water and water vapor are made of the same type of matter: water. The law of conservation of mass says that all physical and chemical changes conserve mass. Conserve means to keep the same. So, the total mass before a physical or chemical change is equal to the total mass after the change.
Step 1: Think about each change. A banana getting ripe on the counter is a chemical change. As a banana ripens, the type of matter in it changes. The peel changes color and the inside becomes softer and sweeter. Deep-frying chicken is a chemical change. The heat causes the matter in the chicken to change. Cooked chicken and raw chicken are different types of matter. Step 2: Look at each answer choice. Both are only physical changes. Both changes are chemical changes. They are not physical changes. Both are chemical changes. Both changes are chemical changes. The type of matter before and after each change is different. Both are caused by heating. Cooking is caused by heating. But a banana getting ripe is not. Both are caused by cooling. Neither change is caused by cooling.

Greetings and closings of letters
A letter starts with a greeting and ends with a closing. For each one, capitalize the first word and end with a comma. You should also capitalize proper nouns, such as Aunt Sue. Dear Aunt Sue, I'm glad you could come to my party, and thank you for the birthday gift. I could not have asked for a better one! Every time I see it, I think of you. With love, Rory
The first greeting is correct: Its first word is capitalized, and it ends with a comma. Ms. Stewart is capitalized because it is a proper noun.

Classify logical fallacies
A strong argument uses valid reasoning and logic in support of a claim. When an argument or claim introduces irrelevant information or misrepresents the issues at hand, it may be committing a logical fallacy. Logical fallacies can hurt a writer's credibility and can lead readers to draw false conclusions. A logical fallacy may present irrelevant information: Fallacy | Description ad hominem | a personal attack meant to discredit one's opponent appeal to nature | an argument that assumes the natural choice is always the best choice bandwagon fallacy | an argument that assumes the popular choice is always the best choice circular reasoning | an argument that supports a claim with the claim itself guilt by association | an unfair negative association with another person or group that is intended to discredit someone or something red herring | the use of a completely unrelated topic in support of a claim A logical fallacy may misrepresent the issues at hand: Fallacy | Description false causation | the assumption that because two things happened together, one caused the other false dichotomy | an argument that presents only two choices when more options exist hasty generalization | a very broad claim based on very little evidence straw man | a misrepresentation of an opponent's position that makes it easier to argue against
The text argues that Norma must be a bad guitar player, because her father is a horrible musician. However, even though Norma's father is a horrible musician, that doesn't necessarily mean that Norma is as well. This illustrates a type of logical fallacy known as guilt by association.

Physical and chemical change
Identify physical and chemical changes
Chemical changes and physical changes are two ways matter can change. In a chemical change, the type of matter changes. Burning a piece of paper is a chemical change. The paper changes into ash and smoke. In a physical change, the type of matter stays the same. Cutting a piece of paper is a physical change. The cut pieces are still made of paper. Ice melting is also a physical change. When ice melts, it changes from a solid to a liquid. But both ice and liquid water are made of the same type of matter: water! This kind of change is called a change of state.
Tying a shoelace is a physical change. The shoelace gets a different shape. But it is still made of the same type of matter.

Recall the source of an allusion
An allusion is a brief mention of something or someone well known, often from mythology, history, or literature. An allusion lets you reference ideas from an entire story in just a few words. The protean nature of the disease makes it difficult to diagnose. The word protean is an allusion to the sea god Proteus in Greek mythology. Because the sea is constantly changing, to describe something as protean suggests that it is variable or in flux.
The source of the allusion an albatross around her neck is a poem. In Samuel Taylor Coleridge's poem "The Rime of the Ancient Mariner," a sailor shoots and kills an albatross, an action that curses the ship and crew. As his crew members die, the Ancient Mariner feels his guilt hanging like the albatross around his neck. The allusion an albatross around her neck means a burden a person must bear.

A compound sentence is made up of two independent clauses joined by a coordinating conjunction such as and, but, or, or so. We saw a flash of lightning, and seconds later we heard the rumble of thunder. A complex sentence is made up of an independent clause and a dependent clause. The dependent clause usually begins with a subordinating conjunction such as after, although, as, because, before, if, since, unless, until, when, or while.

Genes to traits
Inherited and acquired traits: use evidence to support a statement
Organisms, including people, have both inherited and acquired traits. Inherited and acquired traits are gained in different ways. Inherited traits are passed down from biological parents to their offspring through genes. Genes are pieces of hereditary material that contain the instructions that affect inherited traits. Offspring receive their genes, and therefore gain their inherited traits, from their biological parents. Inherited traits do not need to be learned. Acquired traits are gained during a person's life. Some acquired traits, such as riding a bicycle, are gained by learning. Other acquired traits, such as scars, are caused by the environment. Parents do not pass acquired traits down to their offspring.

Informal writing is typically used in casual situations or when communicating with someone you know well. Informal language often expresses familiarity and tends to sound more like speech. It uses more conversational language, such as slang, idioms, abbreviations, imprecise language, and contractions. Formal writing is typically used in academic and business writing or when writing directly to an authority figure. It tends to be more courteous and impersonal, avoiding overly familiar or conversational language. Compare the following sentences. Informal: Yeah, ostriches can't fly, but I think they're awesome. More formal: Ostriches may be flightless, but they're remarkable runners. Most formal: Though flightless, ostriches are remarkable runners.

Measurements are written with both a number and a unit. The unit comes after the number. The unit shows what the number means. Mass is a measurement of how much matter something contains. There are many different units of mass. When you are using metric units, mass may be written with units of grams or kilograms. There are 1,000 grams in 1 kilogram. So, 1 gram is much less than 1 kilogram. A paper clip has a mass of about 1 gram, while a textbook has a mass of about 1 kilogram.

Chemical changes and physical changes are two common ways matter can change. In a chemical change, the type of matter changes. The types of matter before and after a chemical change are always different. Some chemical changes are caused by heating or cooling. For example, burning a piece of paper is a chemical change caused by heating. When paper gets hot enough, it re­acts with oxygen in the air and burns. The paper and oxygen change into ash and smoke. In a physical change, the type of matter stays the same. The types of matter before and after a physical change are always the same. A change of state is a type of physical change.

So, the total mass before a physical or chemical change is equal to the total mass after the change.
Step 1: Think about each change. Tying a shoelace is a physical change. The shoelace gets a different shape. But it is still made of the same type of matter. Breaking a piece of glass is a physical change. The glass gets broken into pieces. But each piece is still made of the same type of matter. Step 2: Look at each answer choice. Both are only physical changes. Both changes are physical changes. No new matter is created. Both are chemical changes. Both changes are physical changes. They are not chemical changes. Both are caused by heating. Neither change is caused by heating. Both are caused by cooling. Neither change is caused by cooling.

What's the difference between weather and climate?
The atmosphere is the layer of air that surrounds Earth. Both weather and climate tell you about the atmosphere. Weather is what the atmosphere is like at a certain place and time. Weather can change quickly. For example, the temperature outside your house might get higher throughout the day. Climate is the pattern of weather in a certain place. For example, summer temperatures in New York are usually higher than winter temperatures.
Read the text carefully. The air was muggy and humid today where Bill lives. Humidity is the amount of water in the air. This passage tells you about the humidity today where Bill lives. It describes the atmosphere at a certain place and time. So, this passage describes the weather.

Designing experiments
Identify questions that can be investigated with a set of materials
Experiments can be designed to answer specific questions. When designing an experiment, you must identify the supplies that are necessary to answer your question. In order to do this, you need to figure out what will be tested and what will be measured during the experiment. Imagine that you are wondering if plants grow to different heights when planted in different types of soil. How might you decide what supplies are necessary to conduct this experiment? First, you need to identify the part of the experiment that will be tested, which is the independent variable. This is usually the part of the experiment that is different or changed. In this case, you would like to know how plants grow in different types of soil. So, you must have different types of soil available. Next, you need to identify the part of the experiment that will be measured or observed, which is the dependent variable. In this experiment, you would like to know if some plants grow taller than others. So, you must be able to compare the plants' heights. To do this, you can observe which plants are taller by looking at them, or you can measure their exact heights with a meterstick. So, if you have different types of soil and can observe or measure the heights of your plants, then you have the supplies you need to investigate your question with an experiment!

Rocks and minerals
Identify minerals using properties
Minerals are the building blocks of rocks. A rock can be made of one or more minerals. Minerals and rocks have the following properties: Property | Mineral | Rock It is a solid. | Yes | Yes It is formed in nature. | Yes | Yes It is not made by organisms. | Yes | Yes It is a pure substance. | Yes | No It has a fixed crystal structure. | Yes | No You can use these properties to tell whether a substance is a mineral, a rock, or neither. Look closely at the last three properties: Minerals and rocks are not made by organisms. Organisms make their own body parts. For example, snails and clams make their shells. Because they are made by organisms, body parts cannot be minerals or rocks. Humans are organisms too. So, substances that humans make by hand or in factories are not minerals or rocks. A mineral is a pure substance, but a rock is not. A pure substance is made of only one type of matter. Minerals are pure substances, but rocks are not. Instead, all rocks are mixtures. A mineral has a fixed crystal structure, but a rock does not. The crystal structure of a substance tells you how the atoms or molecules in the substance are arranged. Different types of minerals have different crystal structures, but all minerals have a fixed crystal structure. This means that the atoms and molecules in different pieces of the same type of mineral are always arranged the same way. However, rocks do not have a fixed crystal structure. So, the arrangement of atoms or molecules in different pieces of the same type of rock may be different!
Compare the properties of each substance to the properties of minerals. Select the substance whose properties do not match those of minerals. Chrysotile is a mineral. Wood is not a pure substance. But all minerals are pure substances. So, wood is not a mineral. Turquoise is a mineral.

Measurements are written with both a number and a unit. The unit comes after the number. The unit shows what the number means. Mass is a measurement of how much matter something contains. There are many different units of mass. When you are using customary units, mass may be written with units of ounces, pounds, or tons. There are 16 ounces in 1 pound and 2,000 pounds in 1 ton. So, 1 ounce is less than 1 pound and much less than 1 ton. A slice of bread has a mass of about 1 ounce, while a can of beans has a mass of about 1 pound. A small car has a mass of about 1 ton.
The best estimate for the mass of a bicycle is 23 pounds. 23 ounces is too light and 23 tons is too heavy.

Pronouns and antecedents
Identify vague pronoun references
When writing, make sure to avoid vague pronoun references. A vague pronoun reference occurs when a pronoun could refer to more than one possible antecedent. When Lisa and Kim finally landed, she breathed a sigh of relief. The pronoun she could refer to either Lisa or Kim, so the meaning of the sentence is unclear. Vague pronoun references can be corrected in one of two ways: 1. Replace the pronoun with its correct antecedent: When Lisa and Kim finally landed, Lisa breathed a sigh of relief. 2. Rewrite the sentence: Lisa breathed a sigh of relief when she and Kim finally landed. A vague pronoun reference also occurs when they, them, their, theirs, it, or its is used without its antecedent. They say that this nail polish dries in less than five minutes. The pronoun they is used without its antecedent, so the meaning of the sentence is unclear. This problem can be fixed by replacing the pronoun with its missing antecedent. The advertisements say that this nail polish dries in less than five minutes.

Pronouns and antecedents
Identify vague pronoun references
When writing, make sure to avoid vague pronoun references. A vague pronoun reference occurs when a pronoun could refer to more than one possible antecedent. When Lisa and Kim finally landed, she breathed a sigh of relief. The pronoun she could refer to either Lisa or Kim, so the meaning of the sentence is unclear. Vague pronoun references can be corrected in one of two ways: 1. Replace the pronoun with its correct antecedent: When Lisa and Kim finally landed, Lisa breathed a sigh of relief. 2. Rewrite the sentence: Lisa breathed a sigh of relief when she and Kim finally landed. A vague pronoun reference also occurs when they, them, their, theirs, it, or its is used without its antecedent. They say that this nail polish dries in less than five minutes. The pronoun they is used without its antecedent, so the meaning of the sentence is unclear. This problem can be fixed by replacing the pronoun with its missing antecedent. The advertisements say that this nail polish dries in less than five minutes.
The second answer choice contains a vague pronoun reference. The pronoun her could refer to Lucy's or Rachel's. The first answer choice shows a possible correction for the vague pronoun reference. Her has been replaced with Rachel's. Lucy asked Rachel to volunteer at the event, so Rachel's absence today is a surprise.

Units and measurement
Choose metric units of volume
Measurements are written with both a number and a unit. The unit comes after the number. The unit shows what the number means. Volume is a measurement of how much space something takes up. There are many different units of volume. When you are using metric units, volume may be written in units of milliliters or liters. There are 1,000 milliliters in 1 liter. So, 1 milliliter is much less than 1 liter. A raindrop has a volume of about 20 milliliters, while a large soda bottle has a volume of 2 liters. The flask shown here measures volumes up to 500 milliliters.
The better estimate for the volume of a bathroom sink is 10 liters. 10 milliliters is too little.

Physical and chemical change
Identify physical and chemical changes
Chemical changes and physical changes are two common ways matter can change. In a chemical change, the type of matter changes. The types of matter before and after a chemical change are always different. Burning a piece of paper is a chemical change. When paper gets hot enough, it reacts with oxygen in the air and burns. The paper and oxygen change into ash and smoke. In a physical change, the type of matter stays the same. The types of matter before and after a physical change are always the same. Cutting a piece of paper is a physical change. The cut pieces are still made of paper. A change of state is a type of physical change. For example, ice melting is a physical change. Ice and liquid water are made of the same type of matter: water.
A piece of apple turning brown is a chemical change. The apple reacts with oxygen in the air and turns into a different type of matter. If you scrape off the brown layer of the apple, the inside is still white. The inside hasn't touched the air. So the chemical change didn't happen to that part of the apple.

Chemical reactions
Compare physical and chemical changes
Matter is made of very small particles called atoms. Atoms can be linked together by chemical bonds. When two or more atoms link together, they form a molecule. In a chemical change, the chemical bonds in the molecules break. The atoms then link together to form different molecules. The types of molecules in matter before and after a chemical change are always different. Some chemical changes are caused by heating or cooling. For example, burning a piece of paper is a chemical change caused by heating. As paper burns, paper molecules react with oxygen molecules in the air. This reaction breaks the chemical bonds in the molecules. The atoms then link together in a different way to form different molecules. For example, carbon dioxide molecules are formed when paper burns. In a physical change, chemical bonds do not break. The types of molecules in matter before and after a physical change are always the same. A change of state is a type of physical change. Changes of state can be caused by heating or cooling. For example, water vaporizing is a physical change that can be caused by heating. Liquid water and water vapor are made of the same type of matter: water. The law of conservation of mass says that all physical and chemical changes conserve mass. Conserve means to keep the same. So, the total mass before a physical or chemical change is equal to the total mass after the change.
Step 1: Think about each change. Mixing lettuce and salad dressing is a physical change. Together, the salad and dressing make a mixture. But making this mixture does not form a different type of matter. Sewing an apron is a physical change. The fabric and thread that make up the apron get a new shape, but the type of matter in each of them does not change. Step 2: Look at each answer choice. Both are only physical changes. Both changes are physical changes. No new matter is created. Both are chemical changes. Both changes are physical changes. They are not chemical changes. Both are caused by heating. Neither change is caused by heating. Both are caused by cooling. Neither change is caused by cooling.

Developing and supporting arguments
Classify logical fallacies
A strong argument uses valid reasoning and logic in support of a claim. When an argument or claim introduces irrelevant information or misrepresents the issues at hand, it may be committing a logical fallacy. Logical fallacies can hurt a writer's credibility and can lead readers to draw false conclusions. A logical fallacy may present irrelevant information: Fallacy | Description ad hominem | a personal attack meant to discredit one's opponent appeal to nature | an argument that assumes the natural choice is always the best choice bandwagon fallacy | an argument that assumes the popular choice is always the best choice circular reasoning | an argument that supports a claim with the claim itself guilt by association | an unfair negative association with another person or group that is intended to discredit someone or something red herring | the use of a completely unrelated topic in support of a claim A logical fallacy may misrepresent the issues at hand: Fallacy | Description false causation | the assumption that because two things happened together, one caused the other false dichotomy | an argument that presents only two choices when more options exist hasty generalization | a very broad claim based on very little evidence straw man | a misrepresentation of an opponent's position that makes it easier to argue against
The text argues that increased park funding was responsible for an increase in littering. However, even though littering increased after funding to parks was increased, that doesn't necessarily mean that the funding was responsible. This illustrates a type of logical fallacy known as false causation.

Traits and heredity
Identify inherited and acquired traits
Organisms, including people, have both inherited and acquired traits. Inherited and acquired traits are gained in different ways. Inherited traits are passed down through families. Children gain these traits from their parents. Inherited traits do not need to be learned. Acquired traits are gained during a person's life. Some acquired traits, such as riding a bicycle, are gained by learning. Other acquired traits, such as scars, are caused by the environment. Children do not inherit their parents' acquired traits.
People are not born knowing how to play soccer. Instead, some people learn how to play soccer. Playing the sport takes practice. So, playing soccer is an acquired trait.

How is temperature related to thermal energy?
All solids, liquids, and gases are made of matter. Matter is made up of tiny particles that are always moving. The energy from the motion of these particles is called thermal energy. Temperature measures how hot or cold matter is. If the particles in matter slow down, the temperature goes down. The matter now has both less thermal energy and a lower temperature.
The two baked potatoes have the same mass but different temperatures. Since the 35°C potato is colder than the 65°C potato, it has less thermal energy.

Measurements are written with both a number and a unit. The unit comes after the number. The unit shows what the number means. Mass is a measurement of how much matter something contains. There are many different units of mass. When you are using metric units, mass may be written with units of grams or kilograms. There are 1,000 grams in 1 kilogram. So, 1 gram is much less than 1 kilogram. A paper clip has a mass of about 1 gram, while a textbook has a mass of about 1 kilogram.

Genes to traits
Genetics vocabulary: dominant and recessive
All organisms have pieces of hereditary material called genes, which are passed from parents to offspring. Genes contain instructions for building the parts of an organism. An organism's genes affect its observable traits, including its appearance, its behavior, and which diseases it may have. Genes may have different alleles, or forms, that can cause different versions of a trait. For example, flower color is a trait in pea plants. The gene for this trait has two possible alleles. Each allele is represented by an uppercase or lowercase letter. The allele F is for purple flowers, and the allele f is for white flowers. Each pea plant has two alleles for the flower color gene—one allele inherited from each parent. An organism's genotype for a gene is its combination of alleles for that gene. So, a pea plant may have a genotype of FF, Ff, or ff for the flower color gene. An organism's phenotype for a trait is its observable version of that trait, which depends on the organism's combination of alleles. A pea plant may have a phenotype of purple flowers or white flowers for the flower color trait. Some traits, like flower color in pea plants, are controlled by a single gene. Most plants and animals have a genotype made up of two alleles for these traits. These two alleles determine whether an organism is homozygous or heterozygous for the gene. An organism with two identical alleles for a gene is homozygous for that gene. A pea plant with the genotype FF or ff is homozygous for the flower color gene. An organism with two different alleles for a gene is heterozygous for that gene. A pea plant with the genotype Ff is heterozygous for the flower color gene. The types of alleles in an organism's genotype determine the organism's phenotype. Some alleles have types called dominant and recessive. These two types can cause different versions of a trait to appear as the organism's phenotype. A dominant allele causes its version of the trait to appear even when the organism also has a recessive allele for the gene. In pea plants, the F allele, which causes purple flowers, is dominant over the f allele. A pea plant with at least one F allele will have the F allele's version of the flower color trait. So, a plant with the genotype FF or Ff will have purple flowers. A recessive allele causes its version of the trait to appear only when the organism does not have any dominant alleles for the gene. In pea plants, the f allele, which causes white flowers, is recessive to the F allele. A pea plant with only f alleles will have the f allele's version of the flower color trait. So, a plant with the genotype ff will have white flowers.
You need to determine the rainbow trout's phenotype for the body color trait. First, consider the alleles in the trout's genotype for the body color gene. Then, decide whether these alleles are dominant or recessive. The allele for a blue body (b) is recessive to the allele for a greenish-brown body (B). This means B is a dominant allele, and b is a recessive allele. The rainbow trout's genotype of Bb has one dominant allele and one recessive allele. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, the rainbow trout's phenotype for the body color trait must be a greenish-brown body.

The types of matter before and after a chemical change are always different. Some chemical changes are caused by heating or cooling. For example, burning a piece of paper is a chemical change caused by heating. When paper gets hot enough, it re­acts with oxygen in the air and burns. The paper and oxygen change into ash and smoke.

So, the total mass before a physical or chemical change is equal to the total mass after the change.
Step 1: Think about each change. A sidewalk heating up in the sun is a physical change. The temperature of the sidewalk goes up, but the sidewalk is still made of the same type of matter. Water vapor condensing on a bathroom mirror is a change of state. So, it is a physical change. The water changes state from gas in the air to liquid water on the mirror. But the water vapor and the liquid water are both made of water. Step 2: Look at each answer choice. Both are only physical changes. Both changes are physical changes. No new matter is created. Both are chemical changes. Both changes are physical changes. They are not chemical changes. Both are caused by heating. A sidewalk getting warm in the sun is caused by heating.

Identify similes and metaphors
Similes and metaphors are figures of speech that compare two things that are not actually alike. A simile compares two things by saying that one is like the other. Similes often use the words like and as. My sister runs like a cheetah. The sister's running and a cheetah's running are compared using the word like. A cheetah is known for running fast, so the simile means that the sister also runs fast. The cat's fur was as dark as the night. The cat's fur and the night are compared using the word as. The night is dark, so the simile means that the cat's fur is also dark. A metaphor compares two things by saying that one of them is the other. Unlike similes, metaphors don't use the word like or as. The snow formed a blanket over the town. The snow and a blanket are compared without the word like or as. A blanket is a large piece of cloth that completely covers a bed. The metaphor makes the reader imagine that the snow becomes a blanket, covering the town completely. Using similes and metaphors in your writing can help you create an interesting picture for the reader.
Pete swam with ease across the swimming pool, like a dolphin. The words Pete and dolphin are compared using the word like. So, the sentence uses a simile.

The first author's name is written in last name, first name format (Smith, Jane). Additional author names are written in first name last name format (Smith, Jane, and John Doe). If there are more than three authors, the first author's name is followed by "et al.," which stands for and others (e.g., Smith, Jane, et al.). Medium of Publication. Each entry must include information about what form the content was communicated in. The most common mediums are "Print" and "Web," but other possibilities include "Film," "E-mail," and "Lecture." Whenever the Medium of Publication is "Web," the date of access (the day, month, and year the webpage was viewed) must be listed directly after the Medium of Publication. Editors and Translators. If a work has an editor or a translator, this information must be added to the Works Cited entry using the appropriate abbreviation. "Ed." stands for edited by. "Trans." stands for translated by. Missing Information. If a work has no known author, the author section of the citation is simply left out. If a work has no available page numbers, the abbreviation "n. pag." is used instead. If a work has no available publication date, the abbreviation "n.d." is used instead. If a work has no available publisher or no available city of publication, the abbreviation "n.p." is used instead.

Classify logical fallacies
A strong argument uses valid reasoning and logic in support of a claim. When an argument or claim introduces irrelevant information or misrepresents the issues at hand, it may be committing a logical fallacy. Logical fallacies can hurt a writer's credibility and can lead readers to draw false conclusions. A logical fallacy may present irrelevant information: Fallacy | Description ad hominem | an attack against the person making the argument, rather than the argument itself appeal to nature | an argument that assumes the natural choice is always the best choice bandwagon fallacy | an argument that assumes the popular choice is always the best choice circular reasoning | an argument that supports a claim with the claim itself guilt by association | an unfair negative association with another person or group that is intended to discredit someone or something A logical fallacy may misrepresent the issues at hand: Fallacy | Description false causation | the assumption that because two things happened together, one caused the other false dichotomy | an argument that presents only two choices when more options exist hasty generalization | a broad claim based on too few observations slippery slope fallacy | the false assumption that a small first step will necessarily lead to extreme consequences straw man | a misrepresentation of an opponent's position that makes it easier to argue against
The text argues that science fiction is of poor quality because one science fiction novel was poorly written. However, one novel does not necessarily reflect the whole genre. This illustrates a type of logical fallacy known as a hasty generalization.

Classify figures of speech: euphemism, hyperbole, oxymoron, paradox
Figures of speech are words or phrases that use language in a nonliteral or unusual way. They can make writing more expressive. A euphemism is a polite or indirect expression that is used to de-emphasize an unpleasant topic. The head of Human Resources would never refer to firing people, only to laying them off. Hyperbole is an obvious exaggeration that is not meant to be taken literally. I ate so much that I think I might explode! An oxymoron is a joining of two seemingly contradictory terms. Some reviewers are calling this book a new classic. A paradox is a statement that might at first appear to be contradictory, but that may in fact contain some truth. Always expect the unexpected.
The text uses a euphemism, a polite or indirect expression that is used to de-emphasize an unpleasant topic. Downsizing is an indirect way of saying that the company is planning on firing employees, closing shops or branches, and/or reducing its budget.

Thermal energy
How are temperature and mass related to thermal energy?
Matter is made of tiny particles called atoms. Atoms are always moving. The energy of moving atoms is called thermal energy. The total amount of thermal energy in matter depends on three things: the type of matter, the amount of matter, and how fast the atoms are moving. Temperature measures how hot or cold matter is. If the atoms in matter slow down, the temperature goes down. The matter now has both less thermal energy and a lower temperature. What happens if the amount of matter changes? A 2-kilogram brick at 70°F has twice as much thermal energy as a 1-kilogram brick at 70°F. The two bricks have the same temperature, but the larger brick has twice as many atoms. So, it has twice as much thermal energy.
The two water balloons are made of the same material and have the same mass. So, the colder water balloon has less thermal energy.

Units and measurement
Choose metric units of mass
Measurements are written with both a number and a unit. The unit comes after the number. The unit shows what the number means. Mass is a measurement of how much matter something contains. There are many different units of mass. When you are using metric units, mass may be written with units of grams or kilograms. There are 1,000 grams in 1 kilogram. So, 1 gram is much less than 1 kilogram. A paper clip has a mass of about 1 gram, while a textbook has a mass of about 1 kilogram.
The better estimate for the mass of a can of soup is 500 grams. 500 kilograms is too heavy.

Editing and revising
Suggest appropriate revisions
During peer review, you read and respond to a fellow student's writing. While there are many methods and strategies that you can use for reviewing a text, it is generally helpful to frame your suggestions in concrete and constructive ways and to consider the following areas for revision: Ideas and development: Does the writer express a clear idea and develop it with evidence, examples, or analysis? Organization: Does the writer order ideas in a clear, logical way so that they build on one another and are easy to follow? Voice: Does the writer maintain an appropriate voice, such as a formal and objective voice in an academic essay or an engaging and expressive voice in a narrative essay? Sentence fluency: Does the writer use sentences that vary in structure and length to create a sense of rhythm and flow within and between sentences, or does the writing sound choppy, rambling, or repetitive? Word choice: Does the writer use words accurately and precisely to create clear, effective, and engaging writing? Grammar and mechanics: Does the writer follow appropriate conventions, using accurate spelling, punctuation, and grammar to create writing that is correct and easy to read?
The writer could best improve his or her word choice by including more figurative language. For example, the writer could make the writing more vivid and engaging by replacing the underlined phrases with these figurative expressions: buzzes with intensity, the thud of, feel the wind like a smack in the face, flying down the hill like a hawk, and rev my engines.

Compare physical and chemical changes
Matter is made of very small particles called atoms. Atoms can be linked together by chemical bonds. When two or more atoms link together, they form a molecule. In a chemical change, the chemical bonds in the molecules break. The atoms then link together to form different molecules. The types of molecules in matter before and after a chemical change are always different. Some chemical changes are caused by heating or cooling. For example, burning a piece of paper is a chemical change caused by heating. As paper burns, paper molecules react with oxygen molecules in the air. This reaction breaks the chemical bonds in the molecules. The atoms then link together in a different way to form different molecules. For example, carbon dioxide molecules are formed when paper burns. In a physical change, chemical bonds do not break. The types of molecules in matter before and after a physical change are always the same. A change of state is a type of physical change. Changes of state can be caused by heating or cooling. For example, water vaporizing is a physical change that can be caused by heating. Liquid water and water vapor are made of the same type of matter: water. The law of conservation of mass says that all physical and chemical changes conserve mass. Conserve means to keep the same. So, the total mass before a physical or chemical change is equal to the total mass after the change.
Step 1: Think about each change. A copper statue turning green is a chemical change. The copper reacts with oxygen in the air. This reaction forms a different type of matter called copper oxide. The copper oxide is green. The breakdown of plant and animal matter by organisms such as fungi and earthworms is called decomposition. A log decomposing in the woods is a chemical change. As the log breaks down, the type of matter in it changes. Over time, the log becomes softer and has a different smell. Step 2: Look at each answer choice. Both are only physical changes. Both changes are chemical changes. They are not physical changes. Both are chemical changes. Both changes are chemical changes. The type of matter before and after each change is different. Both are caused by heating. Neither change is caused by heating. Both are caused by cooling. Neither change is caused by cooling.

Identify inherited and acquired traits
Organisms, including people, have both inherited and acquired traits. Inherited and acquired traits are gained in different ways. Inherited traits are passed down through families. Children gain these traits from their parents. Inherited traits do not need to be learned. Acquired traits are gained during a person's life. Some acquired traits, such as riding a bicycle, are gained by learning. Other acquired traits, such as scars, are caused by the environment. Children do not inherit their parents' acquired traits.
Humans do not choose their skin color. Babies get their skin color from their parents. So, Cora's skin color is an inherited trait.

Time tells you how long the object has spent moving. One unit used to measure time is the hour. Think about objects moving for the same amount of time. The object that is moving the slowest will go the shortest distance in that time. It is moving at the lowest speed.
Look at the distance each speedboat moved and the time it took to move that distance. The direction each speedboat moved does not affect its speed. Notice that each speedboat moved for 10 hours. The speedboat that moved 290 miles moved the shortest distance in that time. So, that speedboat must have moved at the lowest speed.

When a word changes in meaning, its correct usage is often debated. Although a newer sense of the word may be more commonly used, many people consider a word's traditional definition to be the correct usage. Being able to distinguish the different uses of a word can help you use it appropriately for different audiences. Britney perused her notes, carefully preparing for her exam.

Figures of speech are words or phrases that use language in a nonliteral or unusual way. They can make writing more expressive. Anaphora is the repetition of the same word or words at the beginning of several phrases or clauses. We are united. We are powerful. We are winners. Antithesis involves contrasting opposing ideas within a parallel grammatical structure. I want to help, not to hurt. Apostrophe is a direct address to an absent person or a nonhuman entity. Oh, little bird, what makes you sing so beautifully? Assonance is the repetition of a vowel sound in a series of nearby words. Try to light the fire. Chiasmus is an expression in which the second half parallels the first but reverses the order of words. Never let a fool kiss you or a kiss fool you. Understatement involves deliberately representing something as less serious or important than it really is. As you know, it can get a little cold in the Antarctic.

An allusion is a brief mention of something or someone well known, often from mythology, history, or literature. An allusion lets you reference ideas from an entire story in just a few words. The protean nature of the disease makes it difficult to diagnose. The word protean is an allusion to the sea god Proteus in Greek mythology. Because the sea is constantly changing, to describe something as protean suggests that it is variable or in flux.

If the atoms in matter slow down, the temperature goes down. The matter now has both less thermal energy and a lower temperature. What happens if the amount of matter changes? A 1-kilogram brick at 70°F has half as much thermal energy as a 2-kilogram brick at 70°F. The two bricks have the same temperature, but the smaller brick has half as many atoms. So, it has half as much thermal energy.
The two bananas are made of the same material and have the same mass. So, the colder banana has less thermal energy.

Weather and climate
What's the difference between weather and climate?
The atmosphere is the layer of air that surrounds Earth. Both weather and climate tell you about the atmosphere. Weather is what the atmosphere is like at a certain place and time. Weather can change quickly. For example, the temperature outside your house might get higher throughout the day. Climate is the pattern of weather in a certain place. For example, summer temperatures in New York are usually higher than winter temperatures.
Read the text carefully. Morning clouds usually clear up by noon where Estelle lives. This passage tells you about the usual pattern of clouds where Estelle lives. It does not describe what the weather is like on a particular day. So, this passage describes the climate.

Heredity
Inherited and acquired traits: use evidence to support a statement
Organisms, including people, have both inherited and acquired traits. Inherited and acquired traits are gained in different ways. Inherited traits are passed down through families. Children gain these traits from their parents. Inherited traits do not need to be learned. Acquired traits are gained during a person's life. Some acquired traits, such as riding a bicycle, are gained by learning. Other acquired traits, such as scars, are caused by the environment.

Force and motion
How do mass and force affect motion?
A force is a push or a pull. A force can make an object start moving or stop an object that is moving. A force can also make an object speed up, slow down, or change direction. Forces can be different sizes. Think about trying to move a heavy object and a light object. Imagine you want to move them at the same speed. You will need to use a larger force to move the heavy object.
Look for the friend who is heavier. A friend who weighs 33 pounds is heavier than a friend who weighs 26 pounds. So, to move the wagon at the same speed each time, Cole needs to use a larger force to start moving the wagon with a friend who weighs 33 pounds.

Classification
Use evidence to classify mammals, birds, fish, reptiles, and amphibians
Scientists sort animals with similar traits into groups. This is called classification. Classification helps scientists learn about how animals live. How do scientists classify animals? First, they make observations about an animal. Scientists observe the animal's traits, including its body parts and behavior. Then, scientists compare the animal's traits to other animals' traits. Scientists classify animals with similar traits into a group.
To decide if an animal is part of a group, look at the traits of the group. Mammals have the following traits: They feed their offspring milk. They have fur or hair. Compare each animal's traits to the group's traits. Select the animal with traits similar to the group's traits. A black-capped squirrel monkey has the following traits: It feeds its offspring milk. It has fur. A black-capped squirrel monkey has the traits of a mammal. A black-capped squirrel monkey is a mammal. A common toad has the following traits: It spends part of its life in water and part on land. It has moist skin. It makes eggs with no shells. A common toad does not have all of the traits of a mammal. A common toad is an amphibian.

Designing experiments
Identify questions that can be investigated with a set of materials
Experiments can be designed to answer specific questions. When designing an experiment, you must identify the supplies that are necessary to answer your question. In order to do this, you need to figure out what will be tested and what will be measured during the experiment. Imagine that you are wondering if plants grow to different heights when planted in different types of soil. How might you decide what supplies are necessary to conduct this experiment? First, you need to identify the part of the experiment that will be tested, which is the independent variable. This is usually the part of the experiment that is different or changed. In this case, you would like to know how plants grow in different types of soil. So, you must have different types of soil available. Next, you need to identify the part of the experiment that will be measured or observed, which is the dependent variable. In this experiment, you would like to know if some plants grow taller than others. So, you must be able to compare the plants' heights. To do this, you can observe which plants are taller by looking at them, or you can measure their exact heights with a meterstick. So, if you have different types of soil and can observe or measure the heights of your plants, then you have the supplies you need to investigate your question with an experiment!

You might be thinking, 16 what? Is the pencil 16 centimeters long? 16 meters? 16 kilometers? The number 16 on its own does not give you much information about the length of the pencil. That is because the units are missing. Now look at the drawing of the pencil and the ruler. The ruler shows that the units are centimeters. So, the length of the pencil is 16 centimeters. There are 100 centimeters in 1 meter. So, 1 centimeter is much shorter than 1 meter. There are 1,000 meters in 1 kilometer. So, 1 meter is much shorter than 1 kilometer.
The better estimate for the length of a pen is 17 centimeters. 17 kilometers is too long.

The paper changes into ash and smoke. In a physical change, the type of matter stays the same. Cutting a piece of paper is a physical change. The cut pieces are still made of paper. Ice melting is also a physical change. When ice melts, it changes from a solid to a liquid. But both ice and liquid water are made of the same type of matter: water! This kind of change is called a change of state.
Cutting an apple is a physical change. The apple gets a different shape. But it is still made of the same type of matter as the uncut apple.

The first author's name is written in last name, first name format (Smith, Jane). Additional author names are written in first name last name format (Smith, Jane, and John Doe). If there are more than three authors, the first author's name is followed by "et al.," which stands for and others (e.g., Smith, Jane, et al.). Medium of Publication. Each entry must include information about what form the content was communicated in. The most common mediums are "Print" and "Web," but other possibilities include "Film," "E-mail," and "Lecture." Whenever the Medium of Publication is "Web," the date of access (the day, month, and year the webpage was viewed) must be listed directly after the Medium of Publication. Editors and Translators. If a work has an editor or a translator, this information must be added to the Works Cited entry using the appropriate abbreviation. "Ed." stands for edited by. "Trans." stands for translated by. Missing Information. If a work has no known author, the author section of the citation is simply left out. If a work has no available page numbers, the abbreviation "n. pag." is used instead. If a work has no available publication date, the abbreviation "n.d." is used instead. If a work has no available publisher or no available city of publication, the abbreviation "n.p." is used instead.

Identify vague pronoun references
When writing, make sure to avoid vague pronoun references. A vague pronoun reference occurs when a pronoun could refer to more than one possible antecedent. When Lisa and Kim finally landed, she breathed a sigh of relief. The pronoun she could refer to either Lisa or Kim, so the meaning of the sentence is unclear. Vague pronoun references can be corrected in one of two ways: 1. Replace the pronoun with its correct antecedent: When Lisa and Kim finally landed, Lisa breathed a sigh of relief. 2. Rewrite the sentence: Lisa breathed a sigh of relief when she and Kim finally landed. A vague pronoun reference also occurs when they, them, their, theirs, it, or its is used without its antecedent. They say that this nail polish dries in less than five minutes. The pronoun they is used without its antecedent, so the meaning of the sentence is unclear. This problem can be fixed by replacing the pronoun with its missing antecedent. The advertisements say that this nail polish dries in less than five minutes.

Similes and metaphors are figures of speech that compare two things that are not actually alike. A simile compares two things by saying that one is like the other. Similes often use the words like and as. My sister runs like a cheetah. The sister's running and a cheetah's running are compared using the word like. A cheetah is known for running fast, so the simile means that the sister also runs fast. The cat's fur was as dark as the night. The cat's fur and the night are compared using the word as. The night is dark, so the simile means that the cat's fur is also dark. A metaphor compares two things by saying that one of them is the other. Unlike similes, metaphors don't use the word like or as. The snow formed a blanket over the town. The snow and a blanket are compared without the word like or as. A blanket is a large piece of cloth that completely covers a bed. The metaphor makes the reader imagine that the snow becomes a blanket, covering the town completely.
