Description

These are the largest "Happy-Sad" balls we have seen! They are 1.0" in diameter! These two black rubber balls appear to be identical, but have extremely different physical properties. Dropped onto a hard surface, one ball bounces while the other hits the surface and barely bounces at all. Show students that some properties cannot be observed without experimentation. Set includes two balls (one "yes" and one "no").
