Testing the Xpult

on November 22, 2013

5th grade students have been studying simple machines and levers in science.  Students have spent this week testing four different variables on the Xpult, which is a catapult that can hit a precise target.    The class is looking at the launch angle, pull back angle, # of rubber bands, and the type of ball. Students worked in groups taking accurate data that will be graphed next week.   In December, students will be taking the Xpult Challenge and will shoot a ball into a bucket in the middle of the room.  They will try to get ten out of ten shots into the bucket by adjusting each variable.    The Xpult is a great way to illustrate the difference between kinetic and potential energy.
