Our mission is to explore, explain, and sustain life. Teacher - Honors Earth/Space Science, AP Environmental Science, Honors Chemistry. We hope to see you soon! Life Science 1. HS-ESS2-D: Weather and Climate Changes in the atmosphere due to human activity have increased carbon dioxide concentrations and thus affect climate. Carbon is usually bound to other elements in compounds. identify how humans influence the carbon cycle. Activity 11 The Carbon Cycle – How It Works 11-7 Sample Worksheet for the Carbon Cycle 1. The emphasis for middle school is on the geologic process of the rock cycle, and the emphasis in high school is on how biogeochemical cycles that include the cycling of carbon through the ocean, atmosphere, soil, and biosphere (including humans), provide the foundation for living organisms. Sources and Sinks. Explain that they can give their carbon to only one other group, or if they have plenty, they can give the carbon to more than one group. Depending on the number rolled on a die, students either stay in that reservoir or move to another reservoir through some flux mechanism. Run the role-play a number of times, telling students to make different choices about carbon movement each time. There are natural fluctuations in the carbon cycle, but humans have been changing the carbon flows on earth at an unnatural rate. Students know decomposers, including many fungi, insects, and microorganisms, recycle matter from dead plants and animals. Carbon is found in both the living and non-living parts of the planet, as a component in organisms, atmospheric gases, water, and rocks. There are stations around the room that represent Earth's carbon reservoirs. Because carbon dioxide and methane are greenhouse gases that help to control the temperature of the planet, the human-induced increase in atmospheric carbon levels is resulting in a host of climatic changes on our planet. All guests must reserve tickets in advance. Make a list of these items on the board. Divide students evenly into 7 groups and distribute the appropriate role-play card to each group. 2. Develop a model to describe the cycling of Earth's materials and the flow of energy that drives this process.http://www.nextgenscience.org/msess2-earth-systems, MS-LS2-3. These systems interact in multiple ways to affect Earth’s surface materials and processes. carbon: an element that can be found in all living things, carbon dioxide: a chemical compound composed of two oxygen atoms bonded on either side of a carbon atom (CO2); usually present as a gas, atmosphere: the gases surrounding the Earth, decompose: to be broken down physically and chemically by bacterial or fungal action; to rot. 2f. 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. 14-28 of a small, lightweight object to represent carbon, Carbon Cycle Role-Play Cards (7 total, one per group). The objective of this exercise is to have each student become an expert in one of these five processes, and then explain to others in their small group the essentials of this process. Carbon Cycle. All gifts up to $50,000 will be doubled to make twice the impact for our penguin colony — but only until midnight on December 1. (2002). ... 6 c Human activities have increased GHG levels and altered global climate patterns . One at a time, ask each group to give their carbon to another group (or groups). The carbon atoms move from one thing to another in what is called the carbon cycle. Students develop concept maps and compare them in a paragraph or a Venn Diagram. BACKGROUND The element carbon is one of the most basic building blocks of life on earth. d. Biogeochemical Cycles of greenhouse gases/Carbon Cycle: The abundance of greenhouse gases in the atmosphere is controlled by biogeochemical cycles that continually move these components between the ocean, land, life and atmospheric reservoirs. How does this impact our planet? While the Academy is thrilled to reopen, the impact of our 7-month closure will be felt for years to come. Encourage students to provide explanations for the processes underlying each of the arrows, focusing on the content appropriate for your grade level. Upper Saddle River, NJ: Prentice Hall. The Academy is now open to the public. 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. Carbon is an important element for life on earth and can be found in all four major spheres of the planet: biosphere, atmosphere, hydrosphere, and lithosphere (the rigid, rocky outer layer of the earth). 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. If working outside, use chalk to draw out the regions shown below. 6-8: Develop and use a model to describe phenomena. Students know carbon, because of its ability to combine in many ways with itself and other elements, has a central role in the chemistry of living organisms. recognize that there is a finite amount of carbon on earth. Skills and concepts that students must have mastered: How the activity is situated in the course: National or State Education Standards addressed by this activity? As they move their carbon, they must say their script lines to explain the carbon movement that they have chosen. Reservations are required for the rainforest and Shake House. Some salient examples: Ask students if they can think of other human activities that might affect the carbon cycle. Explain that humans have not created more carbon on earth, but that we move carbon from one place to another more quickly than would naturally happen and that this has consequences for the climate of the planet. 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. In this active demonstration, students will model the carbon cycle, and consider way in which human actions play a role. Do NOT copy this pattern. But, the amount of carbon in any given sphere of the planet can increase or decrease depending on the fluctuations of the carbon cycle. EP 2.) Can you create a model of how carbon flows between the biosphere, hydrosphere, atmosphere, and lithosphere?
