Science Experiments for Kids to SEE the Sound

Science Experiments for Kids to SEE the Sound post image

We hear all different kinds of sounds every day. But have you explored sounds with your kids? How is sound generated? Why there are so many different sounds? Many know that sound is certain types of waves. But how to explain the concept to kids? Today we share 7 science activities for kids to “see” the sound. They can be built in units for sound and light, the hearing part of the 5 senses, and any music class.

7 Ways to Help Kids “See” the Sound

Fun science experiments for kids to SEE the sound. It is hard for kids to understand the concept that sound is wave, these activities make teaching easier. Kids can visually grasp the concept and learn science study skills | STEM | five senses unit
Where is sound coming from? How is sound generated? You can do a simple activity to show it to kids. Put a plastic ruler on top of a table, leaving half of the ruler out of the edge of the table. Put a heavy book on top of the part that is on the table. Now quickly push down the end of the ruler that is outside of table edge, and let it go. You will see the ruler quickly swing up and down. Do you hear something? Try move the ruler in or out of the table, so the length sticking out is different. Try to hear the differences in the sound when the length changes.

Another way to show sound to kids is using strings and hangers.

Have you tried music with wine glasses? I love the idea of having two glasses and watching the toothpick moving. It further reinforces the idea that sound is generated with and travel through waves.

A fun extension of the glass experiment is this glow stick xylophone. Have several glasses and fill them with different amount of water, you now have a home-made xylophone. When it is added with glow sticks, it is simply amazing. Make sure to pick small or short glow sticks, so it is easier to fit in the glasses.

The Balloon Amplifier is a fun way to show kids the factor that impact the sound intensity. Make sure to ask kids to hear the sound when they are not holding the balloon next to their ears.

Will louder sound create bigger waves? This sound experiment will show kids with some visual effects. All you need is an empty bowl, a thin plastic film, a rubber band, and some colored sugar crystal.

This cool sound activity is also a good way to demonstrate the relationship between sound and wave, and answer the question will louder sound create bigger waves?

    This page is really helpful for me. I am still in high school but I am taking a child education course and needed to find a science experiment to do with them. Thank you so much for helping me and keep up the good work with your website.

    • Kaden, thanks for the note. You made my day! I am so impressed that you are taking a child education course in high school. So glad to hear this site is helpful.
