Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. What does a plant need to survive and grow? Light Air Water Nutrition Space and an
Optimal temperature
2. What does an animal need to survive and grow? Food water shelter and a space to live
and survive
3. How do animals and plants depend on each other? Plants provide shelter they make
oxygen and when animals die they become natural fertilizers
Gizmo Warm-up
The Cell Energy Cycle Gizmo™ illustrates two
processes that are essential to life: photosynthesis
and cellular respiration.
Although both of these reactions involve a series of
complex steps, the basic reactants and products in
each process are four relatively simple molecules.
1. What is the chemical formula of oxygen? O2
2. Glucose is a simple sugar. What is the chemical
formula of glucose? C6H12O6
3. What is the chemical formula of carbon dioxide? CO2
4. What is the chemical formula of water? H2O

Activity A:
If necessary, click Reset.
Photosynthesis Check that the PHOTOSYNTHESIS tab is
selected. Check that Description is turned on.
Introduction: Photosynthesis occurs in the chloroplast, an organelle found in plant and algae
cells. Within the chloroplast, a green pigment called chlorophyll converts the radiant energy of
sunlight into chemical energy that the plant can use.
Question: What are the reactants and products of photosynthesis?
1. Predict: Of the molecules shown on the CHEMICALS pane, which do you think are
reactants (ingredients) in photosynthesis? Which do you think are products?
Reactants: Co2,H2o Products: O2,C6H12O6
2. Explore: Drag each molecule from the CHEMICALS pane to the chloroplast on the
PHOTOSYNTHESIS pane. If a molecule is a reactant, it will stay in the chloroplast.
Which molecules are reactants in photosynthesis? Co2,H2o
3. Observe: Click Add light and look at the Output. What are the products of photosynthesis?
O2,C6H12O6
4. Summarize: A chemical equation shows reactants on the left side of an arrow, and products
on the right, like this: reactant + reactant product + product.
Based on your observations, what is the chemical equation for photosynthesis?
H2O + CO2 + light or energy ~> O2 + C6H12O6
Turn on Show chemical equation to check. Were you correct? Yes
