Highlights

DefendingScience-Highlight-02

Strike the plates

The hardness of a material is determined by its resistance to physical alterations when a force is applied. Test the hardness of a material by listening to its pitch after striking it with a mallet. The higher the pitch of the sound, the harder the material!

DefendingScience-Highlight-01

Hover Ball

When one fan has a higher speed than the other, notice how the ping pong ball moves towards the side with the lower fan-speed. Altering the fan-speed on both sides causes changes in pressure, and hence changes in the position of the ball.
