Xpult

Students engage in the scientific process in December by collecting data using the Xpult. This catapult allows students to test four different variables. They can adjust the kind of ping pong ball, the launch angle, the pull back angle, and the number of rubber bands. After writing up a lab report that explains the meaning of four different graphs, the students take the Xpult challenge. They are given 10 chances to shoot the ball into a bucket 3 meters away. Most of the students make a perfect 10 shots after all their hard work in the lab.
