Students search for checker pieces to simulate the consumption of renewable and non-renewable energy. Red chips represent renewable energy and black chips represent non-renewable energy. before students arrive place chips around the room. There should be less black chips then red chips(this represents the limited supply of resources). Give little explanation to students before they start. Have students search for 15 seconds and then stop to count chips. Then have them repeat the activity. Once students have searched discuss as a class their findings and finish the accompanying worksheets. This is a great activity to get them moving and show them the difference between renewable and non-renewable resources. Checker chips can be purchased at the dollar store.
