Product Details

What does pressure feel like? In this activity, students hold a small steel ball in one hand and a large foam ball in the other to answer the question—which one is heavier? Students quickly conclude that the small steel ball is heavier. However, when they weigh each ball with a balance, they learn the truth—the large foam ball weighs more. How could this be? Students have misinterpreted their sense of touch as a gauge for weight, when, in actuality, this feeling is a result of pressure. A perfect activity to discuss pressure and density.

Enough materials for five groups of students are provided.
