We have been looking at.pitch.

We filled identical glass bottles with different amounts of water and then tapped them with a beater.

We discovered that the less water in the bottle, the faster the glass vibrates and the higher the pitch.

The more water you add to the bottle the slower the glass vibrates, creating a lower pitch.

We enjoyed playing simple tunes on our bottles.
