Divide the class into teams of two students each.
Ask each pair to think of a terrestrial food chain and an aquatic food chain, and create each of these with words on one side of a piece of paper, using arrows to show the energy flow.
Discuss the food webs they created as a class in Part 1, and tell them that they are now going to construct a food web in their pairs using pictures.
Pass out an assortment of nature and wildlife magazines.
Instruct the groups to make food webs on the other side of their paper by either drawing pictures of the living things in their food chains or finding them in the magazines and gluing them onto the paper. Suggest that they use arrows to show the direction of the flow of energy between the images.
Conclude with an informal discussion using the questions and answers provided in the post-activity assessment of the Assessment section.
