    Worksheet
    Students label the plants and animals of a food web and food chains for producer / consumer and either herbivore / carnivore / omnivore. Students then create their own food web using the animals provided.

    There are four stations where students practice and build the concept that carbon cycles between reservoirs. Each station represents a lesson, and student cycle through the stations to learn from each lesson.

    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.

    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.

    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.
