How can you see sound? Music science for kids

These fun music science experiments for kids are all about making sounds, how we hear sounds, pitch and music! Set up a speaker, a drum and rice first to see sound in action then make a drum, rainstick, guitar and lots more easy music science activities.

How are sounds made?

Did you know sounds are made when an object vibrates? These vibrations make the air around an object vibrate. When the air vibrations reach the ear they shake tiny hairs, which are connected to nerves. It is these nerves that send a message to the brain telling it that a noise has been heard.

Music Science Experiments for Kids

This activity lets children see the effect of  sound vibrations.

How to see sound vibrations

What you need to see sound

• Bowl
• Thin metal baking sheet
• Cling film
• Tape or elastic bands
• Speaker
• Drum
• Drum stick
• Rice

Instructions

Stretch the cling film over the top of your bowl and secure with tape or an elastic band.

Sprinkle a handful of rice over the cling film.

Hold the drum close to the bowl and beat it hard, the rice should jump.

Investigate how the jumping of the rice changes depending on how hard you hit the drum.

Repeat the investigation using a speaker instead of the drum, is it different?

Things to think about

What do you think would happen if you moved the drum further away from the rice bowl?

What do you think would happen if you made a very quiet noise with the drum?

Does changing the pitch of the music affect how the rice jumps?

Why does this happen?

The clingfilm stretched over the bowl is similar to your ear drum. Sound vibrations from the drum travel through the air to the cling film making it vibrate, which makes the rice jump!

More Music Science for Kids

Tin Can Drum

Try making tin can drums. These are just a tin can with a balloon stretched tightly over the top wrapped in gaffer tape.

Try putting different things inside to see how that changes the sound, or try beaters made from different materials.

Straw flute

Simply cut different sized straws and sellotape them together. Gently blow over the top of each to make a sound? Investigate how the length of the straw changes the sound.

Full straw flute instructions.

Music Crafts and Activities for Kids

Frugal Fun for Boys puts a small speaker inside the bowl, stretches a balloon over the top and adds salt so children can see the sound.

We love this homemade rainstick from The Imagination Tree too.

Try our sound absorption and reflection activities.

The Educators Spin on It has some great music ideas for summer.

We love these paper plate tambourines from Creative Family Fun. Do you think a plastic plate would make a different noise?
