Each team lines up at starting line. First player runs to their box, pulls out one item, runs to paper bags and places it in proper bag. Student describes how that item can be kept out of a landfill. Then player runs back to team line and the next player goes. Teammates cannot yell out advice.
Relay continues until trash boxes are empty and players are all sitting down.
Restate the objectives. Ask if there were any items that could have been put into another bag and why.
