Matter is anything that has a mass and takes up space. All matter is made up of atoms. Flowers are matter because they take up space and have mass.

An atom is the smallest unit of a chemical element. I chose a tiny ball to be the background because an atom is very small.

Each element is made up of one type of atom. Fire is an example of an element.

The periodic table is a list of all the chemical elements that exist in the universe. It organizes elements according to the properties of their atoms. There are approximately 120 elements. This picture is the periodic table.

A molecule is formed when two or more atoms join together. It may be the same element or a different element. I chose this background because a molecule is many atoms that are connected.

A compound is formed when two or more DIFFERENT atoms are joined together. All compounds are also molecules, but not all molecules are compounds. Examples of compounds are CO2, NaCl, and H2O2. Some non-examples of compounds are O2 and H2. I chose this background because a compound is many different things compacted together, like this picture where different colored things are all in one shape.

Subscripts tell you how many atoms of each element you need for that molecule. I chose a checklist for the background because subscripts LIST (hypothetically) how many atoms you need. For example, in this scientific equation, the larger threes are coefficients and the smaller twos are subscripts.

3H O + O = 3 HO
2 2 2

Coefficients multiply the number of molecules you are making. I chose this background because coefficients multiply, and I chose a picture of multiplication. In this example, the coefficients are the big 3s and the subscripts are the smaller 2s.

3H O + O = 3H O
2 2 2

Photosynthesis is the process by which plants make their own food. The photosynthesis reaction (only plants do this) is:

6H O + 6CO + sun = C H O + 6O
2 2 6 12 6 2

I chose a picture of a leaf for the background of this slide because during photosynthesis, plants’ leaves turn green.

Cellular respiration is the process by which all living things (including plants) break apart glucose to release energy for their organisms.

The cellular respiration reaction (all organisms do this) is where glucose is broken apart by cells to release energy.

C H O + 6O = 6CO + 6H O + ATP
6 12 6 2 2 2 (Energy)


I chose the background of clouds and trees because it makes it look like the trees are breathing or releasing air into the sky.

Products are the result of an equation or what the chemicals in the result of an equation are called. For example,


C H O + 6O = 6CO + 6H O + ATP
6 12 6 2 2 2 (Energy)


REACTANTS PRODUCTS

I chose this background for this slide because products are the result of an equation and there’s always an equals sign to show the products.

Reactants are chemicals/molecules that you add to get the products of an equation. For example,


C H O + 6O = 6CO + 6H O + ATP
6 12 6 2 2 2 (Energy)

REACTANTS PRODUCTS

I chose this background for this slide because reactants are what you ADD to get the products.

Glucose, or C H O , is the chemical

equation for sugar (that’s why I chose the background I did). It relates to photosynthesis because it is formed when photosynthesis happens. It is used by plants for energy.

Carbon dioxide, or CO , is what trees take in and

what we breathe out. It is also what’s released into the sky and causes climate change, or what we call pollution (that’s why I chose that background). It relates to photosynthesis because when it’s combined with water, it forms carbohydrates, which store energy, which, pretty much, makes photosynthesis happen.

Oxygen, or O, is a chemical that we need to survive. It is also what trees release into the air (it pretty much IS air, that’s why I chose this background). Oxygen relates to photosynthesis because it is released when photosynthesis happens. In cellular respiration, it is used to break down glucose, releasing chemical energy and heat in the process.
