Students will need information regarding the following concepts:
In your journal write what life would be like without insects. Share with your group and each group list common concepts expressed by group members.
Students remain in their groups. Each group is assigned one concept of ecosystems (Producers, Consumers, Decomposers, and Predators). Each group is responsible in designing and constructing a mobile which reflects their assigned ecosystem concept.
Each group will share their findings with the class. Mobiles will be hung in the class.
Students will construct a class bulletin board reflecting ecosystems concepts.
