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). Make sure all of your answers are in
a different color.
1. How do plants on Earth affect the amount of carbon in Earth’s
atmosphere? Plants take in carbon dioxide and process it into
oxygen.
2. Animals eat plants and produce carbon dioxide and water. How do
animals affect the amount of carbon in Earth’s atmosphere?
They eat plants that process carbon dioxide and when they eat theses plants, there are
fewer plants that can process the carbon dioxide.
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? Oceanic Co2, land plants, and
exposed rock
2. Click on Land plants and read the description (at the bottom of the simulation).
How did the carbon atom get from the atmosphere to a plant? Plants use energy
from the sun for photosynthesis. Most of the oxygen is released.
3. Select Land animals. How did the carbon atom get from land plants into the
animal (read the description )? Land animals consume plants for energy.
4. Select Atmospheric CO2. How did the carbon atom get from land animals
, back to the atmosphere? They release carbon dioxide back into the
atmosphere through cellular
