Things can look very similar, but does that make them the same? Hmmmm...
Although the two balls have some similar physical properties, such as size, color, and density, they differ greatly in elasticity. The one which bounces demonstrates an almost perfect elastic collision with a hard surface. Very little of its kinetic energy is converted into heat in the collision. This ball is often referred to as a 'super ball'. The ball which does not bounce demonstrates an almost perfect inelastic collision. Most of the kinetic energy is converted into heat.
Your students may think it's magic, but we all know "It's Science!"
This has great information for teachers on implementing this activity into a course. It contains a full set of directions for a teacher as well as a full student guide to use. It was written by the President's Council of Student Advisors.
Get your kids going with this inquiry activity about collisions.
