How does this impact our planet? The many processes that move carbon from one place to another happen on different time scales. Draw your own carbon cycle on your blank worksheet based on the path of your carbon atom. Warm-Up: o Review what carbon is (an element, the stuff of life) o Discuss where carbon can be found on Earth. Students will explore the different aspects of the carbon cycle on Earth. ... 6 c Human activities have increased GHG levels and altered global climate patterns . 9-12: Develop a model based on evidence to illustrate the relationships between systems or between components of a system. Carbon is found in both the living and non-living parts of the planet, as a component in organisms, atmospheric gases, water, and rocks. Work with your students to draw all of the carbon flows that they acted out, relying on the groups as “experts” for their representation. 5a. 5-LS2-B: Cycles of Matter and Energy Transfer in Ecosystems Matter cycles between the air and soil and among plants, animals, and microbes as these organisms live and die. HS-LS2.B: Cycles of Matter and Energy Transfer in Ecosystems Photosynthesis and cellular respiration are important components of the carbon cycle, in which carbon is exchanged among the biosphere, atmosphere, oceans, and geosphere through chemical, physical, geological, and biological processes. There, the carbon that was stored in their bodies becomes part of the carbon-rich sediment and is eventually carried along, via plate tectonic movement, to subduction zones where it is converted into metamorphic rock. While the Academy is thrilled to reopen, the impact of our 7-month closure will be felt for years to come. There are five fundamental processes involved in the short-term terrestrial organic carbon cycle: photosynthesis, respiration, feeding, death, and decomposition. 2. Mackenzie, F.T. All rights reserved. Topics: Biogeochemical Processes. In general, the short-term carbon cycle encompasses photosynthesis, respiration, and predator-prey transfer of carbon. This activity or unit is just one of many that could help prepare your students to perform the following hypothetical tasks that demonstrate their understanding: 5-ESS2-1. Please do your part to keep our community safe. It could be used in Biology classes as well. The carbon cycle influences crucial life processes such as photosynthesis and respiration, contributes to fossil fuel formation, and impacts the earth’s climate. It is found virtually everywhere -- from plants and animals to pencils, diamonds, soil, and even soda pop. Students know some changes in the earth are due to slow processes, such as erosion, and some changes are due to rapid processes, such as landslides, volcanic eruptions, and earthquakes. Thus, the carbon cycle, includes many carbon-containing compounds, such as carbon dioxide, sugars, and methane. photosynthesis: the process by which plants use carbon dioxide and energy from the sun to build sugar, respiration: the processes by which plant and animal cells break down sugar, which results in carbon dioxide, erosion: the process by which water, ice, wind, or gravity moves weathered rock or soil, sediment: material, such as stones or sand, deposited by water, wind, or glaciers, weathering: the processes by which rocks exposed to the weather change and break down. White pipe cleaners, two per student. If you do not have time for this activity, review with your students that carbon is a common element on earth. EP 2.) Therefore, when each group moves their carbon, they can’t give away all their carbon: they must keep at least one carbon atom. The major human-induced changes result in increased carbon dioxide in the atmosphere. Earth Science 6. How did this affect the carbon cycle? Collect 14-28 of the small, lightweight objects that will represent carbon (e.g. 5-ESS2-A: Earth Materials and Systems Earth’s major systems are the geosphere (solid and molten rock, soil, and sediments), the hydrosphere (water and ice), the atmosphere (air), and the biosphere (living things, including humans). Matter tends to be cycled within an ecosystem, while energy is transformed and eventually exits an ecosystem. Sources and Sinks. Students keep a record of where they have been in this model of the carbon cycle. Teacher Tip:For older students, you can introduce the specific terms for the earth’s four spheres. Masks must be worn properly by all guests ages 3+ at all times. Students know plants use carbon dioxide (CO2) and energy from sunlight to build molecules of sugar and release oxygen. 2g. Their concept maps can be compared to the record. We hope to see you soon! The carbon moves from one sphere to another in an ongoing process known as the carbon cycle. If you have time, consider running the following variations: Explain to students that they just acted out the carbon cycle without human involvement, but humans greatly influence the carbon cycle with some of their activities. Have students guess what movement corresponds to the following human activities: Pull students aside and have them be the humans.
