We showed the students some simple videos/photos of catapults and set them off onto the beach to try and make their own versions. After some playing around, Micah quickly figured out if you put one stick on top of another stick like a seesaw you can flip rocks into the air. Excitement spread and pretty soon launch sites were all over the beach much to the children's delight. ( I apologize in advance if this excitement spreads to your house...)
