Student Exploration: Carbon Cycle Warm-Up & Activities A & B Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: 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 the Earth’s atmosphere? Plants make oxygen from carbon dioxide. 2. Animals eat plants and produce carbon dioxide and water. How do animals affect the amount of carbon in the Earth’s atmosphere? They eat plants that process carbon dioxide and when they eat the plants there are fewer plants producing 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? The oceanic CO2, exposed rocks, and land plants. 2. Click on Land plants and read the description. How did the carbon atom get from the atmosphere to a plant? Through photosynthesis, plants use energy from the sun to turn carbon dioxide into oxygen. 3. Select Land animals. How did the carbon atom get from land plants into the animal? Animals consume plants.

4. Select Atmospheric CO2. How did the carbon atom get from land animals back to the atmosphere? Through cellular respiration, land animals release carbon Reproduction for educational use only. Public sharing or posting prohibited. © 2020 ExploreLearning™ All rights reserved

back into the atmosphere.

Activity A:

Get the Gizmo ready:

Carbon pathways

● 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

Atmospheric CO2

Atmosphere

Atmospheric CO2 comes from volcanoes, burning fossil fuels, and other sources.

Hydrosphere

Coldwater dissolves more carbon dioxide.

Biosphere

Through photosynthesis, marine algae remove carbon dioxide from the ocean.

Oceanic CO2

Marine Plants/Algae

Sediments

Lithosphere

Volcano

Atmospheric CO2

How it got there

Geosphere

Uneaten plants get left on the ocean floor. Sediments are where large amounts of carbon are stored.

Geosphere

The lithosphere has carboncontaining rocks.

Geosphere

rocks are heated to high temps and are melted and carbon dioxide forms.

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, are process practice, and geosphere. Describe each transition briefly. Atmosphere Atmospheric CO2 Volcanoes, burning fossil fuels, and other sources.

Hydrosphere

Biosphere

Oceanic CO2

Marine Algae

Coldwater dissolves CO2

Through photosynthesis the plants remove CO2

Geosphere Sediments Uneaten plants sink to the bottom and become marine sediments.

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 the biosphere, G for the geosphere, or H for the hydrosphere. (You can also use P for the anthroposphere if you like, or just include it in the biosphere.) Path 1:

Atmosphere A –> Oceanic Co2 H –

Path 2:

Atmosphere A –> Land Plants B –> Atmosphere A

Path 3:

Atmosphere A –> Land Plants B –>

4. Explain: Based on the Gizmo, explain how the following transitions might take place: A. Describe at least two ways that carbon can get from a land plant to the atmosphere. 1. Through the process of photosynthesis, taking carbon and turning it into oxygen and that oxygen getting into the atmosphere. 2. Forest fire producing carbon dioxide and it getting into the atmosphere. B. Describe at least two ways that carbon can get from the atmosphere to the hydrosphere. 1. Carbon dissolving into rai water weakening rocks but then the minerals in rocks, as well as the carbon, is being released into the sea. (hydrosphere) 2. Carbo dissolving into cold water heading direction to the hydrosphere. C. Can you find two ways that carbon can get from the ocean to the lithosphere? (The lithosphere is the rigid layer of the Earth, including the crust and part of the mantle.) 1. Trees being turned into coal then being in the lithosphere and heated up and turned into carbon. 2. Shells and coral being weakened by the carbon and turned into limestone and limestone being a part of the lithosphere. D. Describe at least two ways that carbon can get from seashells to the atmosphere. Reproduction for educational use only.

1. when seashells are turned into limestone and are now becoming exposed rocks they are then exposed to the atmosphere. 2. Seashells turning into limestone then becoming a part of cement plants in which carbon is being released into the atmosphere.

Activity B: Human activities

Get the Gizmo ready: ● 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. Question: How does human activity affect the carbon cycle? 1. Describe: Using the Gizmo, determine how coal and petroleum (oil) are formed. Describe the steps required to form each fuel from atmospheric CO2. Coal:

Land plants that accumulate in swaps ca turned into coal.

Petroleum:

Uneaten plants become a part of sedime

2. Explore: Natural gas is a mixture of methane (CH4), ethane (C2H6), and other gases. Find two ways that natural gas forms. List the steps of the two carbon pathways below: Path 1:

Land plants that are compressed from sw coal and as a result, create natural gas.

Path 2:

Uneaten marine plants as animals pile up time petroleum and natural gas is created

How is the formation of natural gas-related to the formation of coal and petroleum? Everything used to make petroleum and coal are compressed and heated so that proess helps release the air that was in the various resources. 3. Describe: Fossil fuels are used in many ways. Using the Gizmo, describe the main use for each fuel. Coal:

Coal is used to generate electricity.

Petroleum:

Petroleum is used for gasoline.

Natural Gas:

Natural gas is used for generating electricity.

In each case, what is the end product of burning fossil fuel, and where does it go? It gets released into the atmosphere.

4. Explore: Another major contribution to atmospheric carbon dioxide is the cement industry. Using the Gizmo, find a carbon atom path from the atmosphere to the cement plant. (Hint: One of the ingredients in cement is limestone.) Path

atmosphere -> Oceanic -> Shells/corals -> Lim Cement Plant

How is carbon dioxide produced in a cement plant? Limestone is heated releasing it into the atmosphere 5. Analyze: Click Reset, then navigate to the Land animals. Select Atmospheric CH4. A. How do land animals create methane?

bacteria break down and undigested materials.

B. Humans raise large numbers of cattle for food. How will these herds of cows affect Earth’s atmosphere?

The cattle will be producing immense amounts of methane so there would be lots of carbon dioxide in the air.

6. Analyze: In many tropical rainforests, people clear land by cutting down trees and burning them. After a few years, the soil runs out of nutrients and cannot be farmed any longer. How does this practice of “slash and burn agriculture” affect Earth’s atmosphere? The pratice of slash and burn affects the earth’s atmosphere in a negative way. Besides the carbon be produced from the practice itself the atmosphere is being filled with carbon from fungi and microbes releasing it from the damaged, and carbon-filled soil. 7. Concludenegatively affects the earth’s atmosphere: In general, how do many human activities influence the carbon cycle? It influences the carbon cycle so there is more carbon being produced than there is in the first place.
