Student Exploration: Carbon Cycle
Directions: Follow the instructions to go through the simulation. Respond to the questions and
prompts in the orange boxes.
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?

2. Animals eat plants and produce carbon dioxide and water. How do animals affect the amount of carbon in
Earth’s 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?
2. Click on Land plants and read the description. How did the carbon atom get from the atmosphere to a
plant?
3. Select Land animals. How did the carbon atom get from land plants into the animal?
4. Select Atmospheric CO2. How did the carbon atom get from land animals back to the atmosphere?
Activity B: Get the Gizmo ready:
Human activities ● Click Reset.
Introduction: Fossil fuels, such as coal, oil, and natural gas, formed over millions of years from the remains
of ancient plants and animals. The burning of fossil fuels, as well as other human activities, increases the
amount of carbon dioxide in the atmosphere.
