Science of Sound Activity for Kids

This post includes an easy and fun science of sound activity for kids. My five year old is into science. I hope to help him nurture this interest so that he holds onto it for a lifetime. Every day he asks if we can do a science experiment. He live tactile experiences. So we do lots of chemistry experiments with various materials such as baking soda, vinegar, flour, oil, corn starch, glue, milk, and water (not all together!).

Well, to be honest, lately I have not been in the mood for messy no matter which way I look at it. So, we’ve been doing lots of physics and physical science, generally. For example, we did loads of life science activitiestested electricity and made a homemade pulley over the summer.

Make a Kazoo

Steps to Make a Kazoo

  1. Decorate the paper roll (optional)
  2. Poke a hole equidistant from each end of the paper roll
  3. Place the piece of plastic over the end of the roll
  4. Tightly place the rubber band over the end of the roll to secure the plastic

Discussion & Inquiry

  1. Encourage the child to hum through the holes. What happens to the sound of your voice?
  2. Encourage the child to hum different sounds like “mmm”, “llll”, “rrrrrr”, etc.
  3. Hum high. Hum low.
  4. Do you feel anything? Vibration?
  5. Where does the sound come from when you blow through the end? The small hole? Through the plastic?
  6. What happens if we move the placement of the small hole?
  7. Test the membrane: What happens if you use different types of plastic or wax paper for the membrane? Make it tighter. Make it looser.
  8. Test diameter: change the role to be wider, narrower
  9. Test length: change the role to be longer, shorter
  10. Test the size of the small hole: change the role to be smaller, bigger
