This diagram illustrates three different types of leaves: simple, palmately compound, and pinnately compound. Simple leaves have undivided blades with either lobed or toothed margins. Compound leaves, in contrast, are composed of multiple leaflets. Compound leaves are further grouped into palmate and pinnate leaves. Palmate leaves have leaflets radiating outwards from the end of the petiole, while the leaflets of a pinnate leave are all arranged around the middle vein. To identify whether a leaf is simple or compound, inspect the base of the leaf. Every leaf, whether simple or compound, will have a bud at the base of its petiole, but individual leaflets of a compound leaf will not. All leaves, regardless of type, serve a common function; to help the plant produce food by converting sunlight into chemical energy that the plant can consume.

The diagram shows four ways leaves can be arranged on their stems. The titles describe the names of these arrangements, which help scientists identify the family and type of plant. A simple leaf arrangement consists of a single leaf attached to the stem. A pinnately compound leaf consists of several leaves or leaflets attached in parallel pairs to a central stem, with a leaf at the tip of the stem. A palmately compound leaf consists of more than three leaflets attached at a central point, reminiscent of a human hand (or palm). A doubly compound leaf is twice divided. The leaflets are arranged in pairs along a stem, which itself is arranged in pairs along a larger stem. The more area a leaf takes up, the more sunlight it can absorb, but in return it will lose more moisture to air flow. Small leaflets, such as doubly compound leaves, reduce both wind resistance and water loss.

The diagram shows an example of ionic bonding. Ionic bonding is a type of chemical bond that occurs between a metallic atom and a nonmetallic atom that join together to form an ionic compound. In the figure, the metallic atom is the sodium atom and the nonmetallic atom is the chlorine atom. During iconic bonding, the metallic atom gives up an electron to the nonmetallic atom. The sodium atom therefore loses an electron while the chlorine atom gains an electron. Because of the electron transfer, each atom now has an unequal number of electrons and protons, thereby becoming an electrically charged ion. An atom that has lost an electron becomes an ion with a positive charge. A positive ion is called a cation. An atom that has gained an electron becomes an ion with a negative charge. A negative ion is called an anion. In short, the sodium atom becomes a sodium cation, whereas the chlorine atom becomes a chloride anion. (Chlorine becomes chloride when it gains an electrical charge.) Because the two ions have opposite electrical charges, they become attracted to each other and bond together, forming the ionic compound sodium chloride.

A covalent bond is the force of attraction that holds together two atoms that share a pair of valence electrons. The shared electrons are attracted to the nuclei of both atoms. This forms a molecule consisting of two or more atoms. Covalent bonds form only between atoms of nonmetals.

The image below shows the different changes in states of matter. A material will change from one state or phase to another at specific combinations of temperature and surrounding pressure. Typically, the pressure is atmospheric pressure, so temperature is the determining factor to the change in state in those cases. The names of the changes in state are melting, freezing, boiling, condensation, sublimation and deposition. The temperature of a material will increase until it reaches the point where the change takes place. It will stay at that temperature until that change is completed. Solids are one of the three phase changes. Their structure and their resistance to change their shape or volume characterize solids. In a solid, the molecules are closely packed together. Liquids are the next of the three phase changes. Liquids are very different from solids, their structure is a bit freer, but not as free as gas. In a liquid phase, the molecules will take the shape of its container or the object that it is in. Gases are the last of the three phase changes. A gas phase is one of the simpler phases, because the gas molecules are the freest. This is because theoretically the molecules behave completely chaotically and they roam anywhere and fill every space of an object or container.

Liquid states of matter are not rigid and have no fixed shape, but have a fixed volume. They too cannot be squashed. Gas states of matter are not rigid and have no fixed shape and no fixed volume. This state of matter can be squashed.

A given kind of matter has the same chemical makeup and the same chemical properties regardless of its state. Thats because state of matter is a physical property. As a result, when matter changes state, it doesnt become a different kind of substance. For example, water is still water whether it exists as ice, liquid water, or water vapor.

Solids that change to gases generally first pass through the liquid state. However, sometimes solids change directly to gases and skip the liquid state. The reverse can also occur. Sometimes gases change directly to solids.

Work is the use of force to move an object. It is directly related to both the force applied to the object and the distance the object moves. Work can be calculated with this equation: Work = Force x Distance.

Energy changes form when something happens. But the total amount of energy always stays the same. The Law of Conservation of Energy says that energy cannot be created or destroyed. Scientists observed that energy could change from one form to another. They also observed that the overall amount of energy did not change.

Why must chemical equations be balanced? Its the law! Matter cannot be created or destroyed in chemical reactions. This is the law of conservation of mass. In every chemical reaction, the same mass of matter must end up in the products as started in the reactants. Balanced chemical equations show that mass is conserved in chemical reactions.

Some reactions need extra help to occur quickly. They need another substance called a catalyst. A catalyst is a substance that increases the rate of a chemical reaction. A catalyst isnt a reactant, so it isnt changed or used up in the reaction. Therefore, it can catalyze many other reactions.

There are three states of matter. These three states include solid, liquid, and gas. Solid states of matter are rigid and have a fixed shape and fixed volume. They cannot be squashed. Liquid states of matter are not rigid and have no fixed shape, but have a fixed volume. They too cannot be squashed. Gas states of matter are not rigid and have no fixed shape and no fixed volume. This state of matter can be squashed.
