Carbon Cycle Gizmo
The Carbon Cycle Gizmo is an interactive simulation that allows students to explore the processes involved in the carbon cycle. The Gizmo includes a variety of components that represent the different reservoirs of carbon in the environment, including the atmosphere, oceans, land, and living organisms.
Students can use the Gizmo to track the flow of carbon through these reservoirs and to investigate the effects of human activities on the carbon cycle.
The Gizmo is divided into three main sections. The first section shows the global carbon cycle, which includes the atmosphere, oceans, land, and living organisms. The second section shows the carbon cycle in a forest ecosystem, which includes trees, plants, soil, and animals.
The third section shows the carbon cycle in a human ecosystem, which includes cities, factories, and cars.
The Gizmo includes a number of features that allow students to explore the carbon cycle in detail. Students can use the Gizmo to:
- Track the flow of carbon through the different reservoirs of the carbon cycle.
- Investigate the effects of human activities on the carbon cycle.
- Create their own scenarios to explore the effects of different factors on the carbon cycle.
Carbon Reservoirs
The carbon cycle involves the continuous exchange of carbon among different reservoirs, including the atmosphere, oceans, biosphere, and geosphere. These reservoirs play crucial roles in regulating the Earth’s climate and sustaining life.
Atmosphere
The atmosphere is the primary reservoir for carbon dioxide (CO2). CO2 is released into the atmosphere through various processes, including volcanic eruptions, respiration, and the burning of fossil fuels. The atmosphere also absorbs CO2 from the oceans and land.
Oceans
The oceans are a significant carbon reservoir, containing vast amounts of dissolved CO2. CO2 dissolves in seawater and forms carbonic acid, which can react with other chemicals to form carbonate minerals. These minerals are then deposited on the ocean floor, creating sedimentary rocks.
Biosphere
The biosphere includes all living organisms on Earth. Plants absorb CO2 from the atmosphere during photosynthesis, using it to produce food and grow. Animals consume plants and release CO2 back into the atmosphere through respiration.
Geosphere
The geosphere includes the Earth’s crust, mantle, and core. Carbon is stored in the geosphere in various forms, including fossil fuels (coal, oil, and natural gas), carbonate rocks (limestone and dolomite), and organic matter in soils.
Factors Influencing Carbon Distribution
The distribution of carbon among the reservoirs is influenced by several factors, including:
-
-*Photosynthesis and Respiration
Photosynthesis removes CO2 from the atmosphere, while respiration releases it back.
-*Ocean Circulation
Ocean currents transport CO2 between the surface and deep ocean, affecting its distribution.
-*Weathering of Rocks
Weathering of carbonate rocks releases CO2 into the atmosphere.
-*Volcanic Eruptions
Volcanic eruptions emit large amounts of CO2 into the atmosphere.
-*Human Activities
Human activities, such as burning fossil fuels and deforestation, contribute significantly to atmospheric CO2 levels.
Carbon Fluxes
Carbon fluxes represent the movement of carbon between different reservoirs in the carbon cycle. These fluxes are crucial in maintaining the balance of carbon in the Earth’s system. The Gizmo includes several key carbon fluxes:
- Photosynthesis: Plants and other organisms use sunlight to convert carbon dioxide and water into glucose and oxygen. This process removes carbon dioxide from the atmosphere and stores it in plant biomass.
- Cellular respiration: All living organisms use oxygen to break down glucose for energy, releasing carbon dioxide as a waste product. This process returns carbon dioxide to the atmosphere.
- Decomposition: When plants and animals die, they decompose, releasing carbon dioxide back into the atmosphere. This process also releases nutrients that can be used by plants for photosynthesis.
- Fossil fuel combustion: Humans burn fossil fuels, such as coal, oil, and natural gas, releasing large amounts of carbon dioxide into the atmosphere. This process contributes to the increase in atmospheric carbon dioxide levels.
- Ocean-atmosphere exchange: Carbon dioxide dissolves in the ocean, where it can be taken up by marine organisms or released back into the atmosphere.
These carbon fluxes contribute to the overall carbon cycle by transferring carbon between different reservoirs. The rates of these fluxes can be affected by various factors, such as:
- Temperature: Higher temperatures increase the rates of photosynthesis and decomposition, while decreasing the solubility of carbon dioxide in the ocean.
- Sunlight: Photosynthesis is dependent on sunlight, so the amount of sunlight available affects the rate of carbon uptake by plants.
- Nutrient availability: The availability of nutrients, such as nitrogen and phosphorus, can limit the rate of photosynthesis.
- Human activities: Human activities, such as fossil fuel combustion and deforestation, can significantly alter the rates of carbon fluxes.
Understanding carbon fluxes is crucial for managing the Earth’s carbon cycle and mitigating the effects of climate change. By reducing fossil fuel emissions and promoting sustainable practices, we can help maintain the balance of carbon in the Earth’s system.
Human Impact on the Carbon Cycle
Human activities significantly impact the carbon cycle, particularly through the burning of fossil fuels. The combustion of fossil fuels, such as coal, oil, and natural gas, releases large amounts of carbon dioxide (CO2) into the atmosphere.
The release of CO2 from fossil fuel combustion disrupts the natural balance of the carbon cycle, leading to an increase in atmospheric CO2 concentrations. This increase in CO2 contributes to the greenhouse effect, trapping heat in the atmosphere and causing global temperatures to rise.
Fossil Fuel Combustion and Carbon Fluxes
Fossil fuel combustion significantly alters carbon fluxes within the carbon cycle. When fossil fuels are burned, the carbon stored within these fuels is released as CO2, which enters the atmosphere. This process increases the amount of carbon in the atmosphere, disrupting the natural balance of the carbon cycle.
The increased CO2 in the atmosphere leads to changes in carbon fluxes between the atmosphere and other reservoirs. For instance, the ocean absorbs CO2 from the atmosphere, acting as a carbon sink. However, as atmospheric CO2 concentrations rise, the ocean’s ability to absorb CO2 decreases, leading to a reduction in the ocean’s carbon sink capacity.
Potential Consequences of Human-Induced Changes
Human-induced changes to the carbon cycle have several potential consequences. The increase in atmospheric CO2 concentrations contributes to climate change, leading to rising global temperatures, changes in precipitation patterns, and more frequent and severe extreme weather events.
Additionally, changes in the carbon cycle can impact ecosystems and biodiversity. Increased CO2 levels can affect plant growth and distribution, potentially disrupting food webs and altering habitats for various species.

The data collected from the Gizmo can be used to draw conclusions about the carbon cycle. For example, students can use the data to determine how different factors affect the flow of carbon through the cycle. They can also use the data to determine how human activities are affecting the carbon cycle.
One way to interpret the data is to look at the trends in the data. For example, students can look at the trend in the amount of carbon dioxide in the atmosphere over time. They can then use this trend to draw conclusions about the factors that are affecting the amount of carbon dioxide in the atmosphere.
