  1. Description: Goals: Distinguish between food chains and webs. Students create food chains and food webs to interpret energy flow in ecosystems.

  2. Objectives: Design and create food chains and food webs. Explain the flow of energy within an ecosystem.

  3. Warm Up: Watch Video Q = List 10 Facts about food chains/webs from the video. A = vary

  4. Insert Bill Nye video here

  5. Many Food Chains in each Ecosystem

  6. If you take all of the food chains in an ecosystem you get a Food Web

  7. Use the packet of pictures to… • Categorize the organisms into: • Original Source of Energy • Producers • Herbivores • Carnivores • Now make three food chains • Include a primary producer, primary consumer, secondary consumer, top consumer I’ll check these BEFORE we can move on!

  8. Exit Ticket: Q = Which is more complex - food chains or webs? What do trophic pyramids and food chains have in common? What directions do the arrows point in a food web/chain? A = Food Webs Both relate the transfer of energy through means of food. Where the energy is GOING (e.g. to predator)

  9. Objectives: Design and create food chains and food webs. Explain the flow of energy within an ecosystem.
