We need to cause them to look for alternatives. Children may add the pollution at each step of the way. Students can write or draw about Freddy the Fish and tell how they think Freddy the Fish feels. Rewrite Freddy s story to make a happy ending instead of a bad one. Talk about food chains.
Children make paper chains and illustrate animals and plants to be glued onto the paper chains.
Be sure to include plant life and fish in your example food chain for the children. Use a filtration system to clean up Freddy s habitat. Older students can devise their own filtration system. Students may compete to see which filtration system cleans the water the best. Fill metal tray with loose soil and pebbles.
