Video Lesson Tutorial
Tools & Materials
Popsicle stick
Two cap erasers
Index card
Scissors
String
Tape
Wide rubber band
Assembly
1. Put a cap eraser on each end of the popsicle stick.
2. Trim an index card so it fits in the space between the two erasers on the stick.
3. Tape the card to the craft stick.
4. Cut enough string to safely swing the bee buzzer. Then tie the string next to one of the erasers, making several knots so it's secure.
5. Once the string is tied to you bee buzzer, stretch the rubber band around the popsicle stick from one eraser to the other, and make sure it's snugly in place.
6. Make sure the area is clear. Then hold the end of the string and swing your bee buzzer in a circle. You should hear a sound like bees buzzing!
What's Going On?
When you spin your bee buzzer, moving air makes the rubber band vibrate. The air flowing over the rubber band makes it vibrate the same way that wind blowing over a flag makes it wave.
Sound is produced by those vibrations, in the same way that vibrating strings on a guitar or violin produce sound. The index card amplifies the sound.
If your bee buzzer doesn’t seem to be working, check to be sure that the rubber band isn’t twisted, and that the string isn’t touching the rubber band. Either of these things could stop the sound.
