In the Exploratorium the Campers have a choice of experiments and equipment that let them explore the science around them with hands-on activities using common household materials. This week the campers investigated gravity and flight with experiments using water and air. While some made rockets and launchers, other campers figured out the best way to drop an egg safely to the floor below. Another group of campers wanted to see which model paper airplane design flew the farthest, and many of the campers made running fans with motors and batteries. Many of the campers also spent some time exploring nature by chasing butterflies and inspecting worms.
