Using balls to represent wave energy

Today in science class, we used various balls with different densities to represent a wave. Waves act in a similar manner as when a ball is rolled towards a flat surface. We worked with partners to find out if there is a certain way that a ball (wave) acts or behaves.

Create a blog post stating your observations, analysis and conclusion.

How is the angle at which the ball (wave) hits the wall related to the angle at which it bounces back?

Does energy (density or speed of the ball) affect the waves path?

What happens to a wave as it hits a surface it cannot pass through?
