What kids do
“Make a water xylophone! Which glass sings highest?”
- Glass 1
- Glass 2
- Glass 3
- Glass 4
- Glass 5
- Color the water level in each glass. Lowest sound to highest:
- More water makes the sound…
- A song I can play:
How to run it
- Use glass jars or bottles and tap gently with a spoon.
- Add a drop of food coloring so levels are easy to see.
- Blowing across the top gives the opposite result, so try both!
Talk about it
- Why does the water change the sound?
- Where else do you hear high and low sounds?
- Which animals make low sounds?
