Begin again, this time with a selection of plants and animals found near your school. This can lead to a class discussion of how fragile the chains are and how disturbing one species in an ecosystem can affect many other plants or animals, directly and indirectly. Never Break the Chain Create a card game with your students. Make cards with the names and pictures of animals found in the Okavango Delta, as well as grass, trees, and decaying logs. You can print the pictures to color here online or have students sketch their own.
Students can create a food chain one card at a time.
Give each student an equal number of cards and place one face up where all can see it. Taking turns, students can place one of their cards on the pile or they can pass. Some valid chains include grass to lechwe to crocodile and decaying log to termite to pangolin to wild dog. The first student to place his or her last card wins. Help your class create a game for the playground or gym in which each student plays an animal that can be tagged only by animals that would hunt it.
