Work & Energy
Why is work and energy different in some ways and similar in other ways? Find out the “how and why” using the demonstrations and hands-on activities in this collection. Experience the ultimate “super ball” – the Dropper Popper -where stored energy is released upon impact, and the popper bounces higher than your head! Witness how energy “loss” is dissipated as heat when our Colliding Steel Spheres convert mechanical energy into heat energy. Have your students design and conduct an experiment to explore energy transfer, the relationship of gravitational potential energy to mass and height, and the transformation of potential energy to kinetic energy. These products engage students' critical thinking and problem solving skills.
