    Project
    In this carbon cycle project, students will model how a carbon atom makes a round trip from a person through the atmosphere and ecosystem and end finally back in the same person. This carbon cycle project video covers concepts like photosynthesis, consumption, cellular respiration, carbon reservoirs, and the 10% rule for energy flow.

    The Carbon Dice Game Lab

    Free Lesson Plan
     
    Lab
    Students play the roles of individual carbon atoms going through carbon-transforming processes in an ecosystem. Key ideas include (a) carbon-transforming processes in individual organisms (eating, digestion, biosynthesis, photosynthesis, cellular respiration and death/defecation) move carbon atoms from one carbon pool to another, (b) carbon atoms visit some pools much more often than others, and (c) the game is a model of how atoms move through ecosystems—like real ecosystems in some ways and unlike it in others.

    Lab
    In this cellular respiration modeling lab, students act out the three parts of cellular respiration: glycolysis, electron transport chain, and the Kreb cycle. Students at the end of the lab will learn the chemical formula for cellular respiration, how ATP is synthesized using NADH and FADH2, and why acetyl Co-A is broken down and CO2 gas is released as a waste product. This cellular respiration modeling lab is great for visual and kinesthetic learners.

    Worksheet
    In this activity students are reminded of why organisms need to lose carbon atoms: They need to use the chemical energy in organic molecules. All carbon-transforming processes use chemical energy for some cell functions; then lose heat to the environment (this heat is ultimately radiated into outer space). Thus, matter cycles; energy flows in ecosystems.

    Lab
    In this activity students shift to following a pulse of 500 carbon atoms through all the carbon pools in an ecosystem, considering the carbon transforming processes (eating, digestion, biosynthesis, photosynthesis, cellular respiration and death/defecation) that move atoms from one pool to another. They see how the pattern they observed in Lesson 2—the organic matter pyramid—emerges from these carbon-transforming processes.

    Food Chain Lab - Owl Pellets
    Free Student Handout
     
    Lab
    In this food chain lab, students dissect owl pellets to learn how the owl is part of a food chain. Since the owl regurgitates these compact pellets, owl pellets are undigested parts that the owl eats, which contain fur and bones of small rodents. Dry pellets will not smell and are acceptable for students to handle with gloves.
