Student Exploration: Carbon Cycle Vocabulary: atmosphere, biomass, biosphere, carbon reservoir, carbon sink, fossil fuel, geosphere, greenhouse gas, hydrosphere, lithosphere, photosynthesis Prior K ... nowledge 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? as there are more animals the carbon will increase the plants take in the carbon that is in the air to start the process of photosynthesis which helps us because as they take in the carbon it reduces how much is in the air which is good for us to the land plants the carbon atom gets there by the process of photosynthesis the animals eat the plants or the other animals which have ate the plants for energy only a small amount of plant carbon is consumed the animal release the carbon back into the air by the process of cellular respiration Karim Ayoub 3/4/21 https://www.coursehero.com/file/83123345/carbonpdf/ This study resource was shared via CourseHero.com2018 Activity A: Carbon pathways Get the Gizmo ready: x Click Reset. Introduction: Earth can be divided into four systems. The atmosphere is the air above Earth’s surface. The hydrosphere is composed of all of Earth’s water. The geosphere is the rocky, non-living part of Earth. The biosphere consists of all living things, including people. Some scientists use the term “anthroposphere” to describe everything made or modified by humans. Question: How does carbon move between the atmosphere, hydrosphere, biosphere, and geosphere? 1. Explore: Use the Gizmo to create a path for carbon that begins and ends in the atmosphere. Fill in the steps in the path below. Then, label each location with the system it represents. Finally, summarize very briefly how the carbon atom got to that location. Carbon path System How it got there Atmospheric CO2 Atmosphere Atmospheric CO2 comes from volcanoes, burning fossil fuels, and other sources. 2. Create: Click Reset. Use the Gizmo to create a path in which the carbon atom goes from the atmosphere to the hydrosphere, biosphere and geosphere. Describe each transition briefly. Atmosphere Hydrosphere Biosphere Geosphere Atmospheric CO2 Volcanoes, burning fossil fuels, and other sources. (Activity A continued on next page) Ocean Rain water breaks down exposed rocks. Marine plants/algae During photosynthesis, marine algae and plants remove carbon dioxide Sediments Uneaten plants and algae drift down to the ocean floor and becomes apart of marine sediments I did it on separate docs and took screenshot upload it https://www.coursehero.com/file/83123345/carbonpdf/ This study resource was shared via CourseHero.com2018 Activity A (continued from previous page) 3. Explore: Use the Gizmo to create three more carbon paths, each starting and ending in the atmosphere. Label each location with A for atmosphere, B for biosphere, G for geosphere, or H for hydrosphere. (You can also use P for anthroposphere if you like, or just include it in the biosphere.) - - - - - - Continued [Show More]
