Noisy Paper Sound Science Experiment
In this fun and easy sound science experiment, we’re going to explore and investigate sound by making noisy paper. This is a great sound science activity that easily helps visualize the relationship between mechanical vibrations and the resulting sound. You will easily be able to watch the paper vibrate and hear the sound the noisy paper makes.
- Two pieces of printer paper
- Hold the two pieces of paper up in front of your mouth.
- Pull the bottom piece out about a half an inch.
- Blow strongly toward the middle of the two papers.
- You may have to adjust your distance from the paper, how hard you are blowing, or how far out the bottom sheet of paper is from the top.
- You should hear a loud vibrating noise.
How it Works:
As you blow across the paper, a stream of air works its way between the two sheets of paper. The air cause the paper to start vibrating. The quickly moving paper creates sound waves that travel to your ears as sound. Watch the differences in the speed of the paper movement as you change the force at which you blow air across the noisy paper and observe the differences in the sound.
Make This A Science Project:
Use different types of paper like construction paper or cardstock. Adjust the length of which you pull out the bottom sheet of paper. Try adding additional pieces of paper.
