SCIENCE 101_ CARBON CYCLE GIZMO (Complete and Full Answers to Questions from Activities A, B, and C) Graded A Student Exploration: Carbon Cycle Vocabulary (refer to vocab file located on the Gizmo s... ite for definitions): atmosphere, biomass, biosphere, carbon reservoir, carbon sink, fossil fuel, geosphere, greenhouse gas, hydrosphere, lithosphere, photosynthesis 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 take in carbon and then give out oxygen 2. Animals eat plants and produce carbon dioxide and water. How do animals affect the amount of carbon in Earth’s atmosphere? Animals take in oxygen and give out carbon 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? The ocean, exposed rocks, land plants, and land animals 2. Click on Land plants and read the description. How did the carbon atom get from the atmosphere to a plant? The plants take it in to make energy for themselves through photosynthesis 3. Select Land animals. How did the carbon atom get from land plants into the animal? They ate the plants to make energy for themselves through cellular respiration 4. Select Atmospheric CO2. How did the carbon atom get from land animals back to the atmosphere? They released it back through cellular respiration, basically [Show More]
