Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
In the process of photosynthesis, plants take in carbon dioxide (CO2) from the
atmosphere and water (H2O) from the soil. Using the energy of sunlight, plants build
molecules of glucose (C6H12O6) and oxygen (O2).
1. How do plants on Earth affect the amount of carbon in Earth’s atmosphere?
Plants decrease the amount of C02 and convert it to Oxygen.
2. Animals eat plants and produce carbon dioxide and water. How do animals
affect the amount of carbon in Earth’s atmosphere? Animals increase the
amount of C02 in the
atmosphere.
Gizmo Warm-up
The Carbon Cycle Gizmo allows you to follow the
many paths an atom of carbon can take through
Earth’s systems. To begin, notice the black carbon
atom in the Atmospheric CO2 area, highlighted in
yellow. The glowing blue areas represent possible
locations the carbon atom could go next.
1. From Earth’s atmosphere, where can the carbon
atom go next? It can go to exposed rock, land
plants, or oceanic CO2.
2. Click on Land plants and read the description. How did the carbon atom get from
the atmosphere to a plant? During photosynthesis, plants use the energy of
