Beware the Jumping Giraffe
In Physics, students observed the conservation of energy in the bounce of a small zoo animal pop-up toy. First, they measured the mass of the toy and the length of its compressed and un-compressed spring, then conducted several trials to measure how high it bounced, repeating the trials with additional weights attached to the toy. They used the data in a series of calculations, including the gravitational potential energy, kinetic energy, and spring constant.
