Engineering: Crazy Action Contraptions
Turn a pull, drop, or hidden trigger into action with contraptions you build. In pairs, campers use LEGO® pieces to build a do-nothing machine, coat-hanger daredevil, trapdoor cable car, parachute drop, fishing pole, and crane. They also build a wall rocket racer and zipline. Partners find what releases a trapdoor or starts a moving part, then predict and test the results. Even the do-nothing machine has plenty going on inside. The Crazy Contraption Challenge puts their creations to work. Bring a snack and drink for class breaks.
*Exact age/grade availability depends on each district's listing.
What Students Will Do
Learn engineering concepts through crazy machines like a rubber band racer and balloon powered car.
