What this lesson teaches
This activity helps students understand ecosystems and the interdependence of living things. They will learn about producers, consumers, and decomposers in a hands-on way.

How the activity runs
- Gather materials like paper, markers, and small toys or figures.
- Divide roles: some will be producers, others consumers, and decomposers.
- Draw a large food chain diagram on paper with your roles.
The learning connection
Experiencing the food chain firsthand solidifies concepts better than lectures. Engaging in simulation fosters critical thinking and teamwork skills.
Try it with your learner
1. Draw 3 different organisms on separate pieces of paper: a plant, an herbivore, and a carnivore. 2. Cut out the drawings and label each organism. 3. Arrange the organisms in a line to represent the food chain: plant → herbivore → carnivore. 4. Use glue to attach the organisms to another piece of paper in the correct order. 5. Connect the organisms with string to show the relationship between them. 6. What did you notice about how energy flows in your food chain?
