Food Chains and Energy Flow Kit (491) In Stock Now

Students are introduced to an aquatic food web diagram that has 3 missing “mystery” organisms. After drawing inferences about those mystery organisms, a microscopic investigation is done to solve a “who eats whom” mystery. Throughout, students seek to construct and refine their understanding of energy flow and matter cycles to answer the driving question, “How does energy flow through food chains in an ecosystem?”

Learning Objectives: Construct a food chain using microscopic observations of 3 microorganisms. Describe the nature of how energy flows through food chains.Use physical and mathematical models to analyze the loss of energy between trophic levels. Explain how the flow of energy through food chains obeys the law of conservation of energy.

Note: This does NOT come with perishables; Didinium will starve to death if not used within 1 day of receiving. You will need to order the following from Carolina: Didimium and Paramecium.
