Matter: anything that takes up space and has mass. All matter is made of atoms.
I choose this picture because water takes up space and has mass so it is matter

Atom definition- the smallest unit of a chemical element. I choose this picture because you can see the protons and neutrons in the center of the atom or the in the nucleus( center of the atom). And the electrons on the outside.

Element definition- each element is made of only one kind of atom. There is about 120 different types of elements. I choose this picture because oxygen is one of the many different kids of elements.

Periodic table definition-a list of all the chemical elements that exist in the universe ( that have been discovered by humans so far) The periodic table Categorizes and organizes elements according to the properties of their atoms. I choose this picture because it shows a picture of the periodic table.

Molecule- formed when 2 or more atoms join together. These may be 2 of the same atom or 2 different atoms. I choose this picture because H20 is a type of molecule. 2 hydrogen and 1 oxygen.

Compound- formed when 2 or more different atoms are combined. All compounds are molecules but not all molecules are compounds.
I choose this picture because it is a picture of water. And water is made up of hydrogen and oxygen. Hydrogen and oxygen are 2 different elements thus it is a compound.

Subscript- tells you how many atoms of each element are in that molecule. I choose this picture because it says d2 and the 2 part is a subscript.

Coefficient- multiply the number of molecules you are making. I choose this picture because the first 2 in the picture is the coefficient. It tells you there are 2 molecules.

Photosynthesis - is the process by which plants make their own food. I choose this picture because it’s a plant absorbing the sun to make its food.

Cellular respiration- the process by which the cells of all living things break about glucose to release energy. I choose this picture because a Rubix cube is breaking apart. Just like glucose breaks apart.

Product- what comes out of a reaction. I choose this picture because apple juice is the product of apples.

Reactants- what goes into a reaction. I choose this picture because the apples are the reactants and the apple juice is the product

Glucose - is the product of photosynthesis. Glucose is a type of sugar. I choose this picture because there are sugar cubes in this picture. And glucose is a type of sugar.

Carbon dioxide - is a reactant of photosynthesis. I choose this picture because co2 is carbon dioxide

Oxygen- is a product of photosynthesis. Oxygen is what humans breath. I choose this picture because it shows a man breathing in oxygen.
