Hot Science: The Symphony of Jam
In this fun science experiment for kids, use water to create your own symphony of jam!
What you need:
- - 6-8 empty jam jars (the same size)
- - Water
- - Metal spoon
1. Line up the jam jars next to each other without touching.
2. Gradually add water to each jar until the last one is almost full up to the rim.
3. Use your spoon to tap on each jar. Each jar will produce different sounds based on how much water the jar is filled with. Try different sound combinations and make up a catchy tune!
Sounds are made by vibrating objects. Vibrating means the number of times an object moves back and forth. The amount of water in a glass will affect how much an object vibrates. Therefore, the glasses with more water will produce a lower pitch, and those with less water will produce a higher pitch sound.
