Make a Xylophone
5-6 glass beakers
Water
Wooden pencil
What you do
Line the beaker up
Pour different amount of water in the beaker
Lowest to highest
Use a pencil and tap to hear the noise
What happened
It makes different sounds
Least water made highest.
Why
The sound waves travel
trough liquid. By chaging the the amount of water, the sound waves change.
