Sound waves are everywhere, but they’re often invisible to the naked eye. However, learning about sound waves doesn’t have to be boring—it can be a lot of fun, especially for primary school children! By turning sound science into playful, hands-on activities, you can help kids understand the concept of sound waves in ways that are engaging and memorable. Here are some fun and simple activities to teach children about sound waves!
1. Water Ripple Experiment
This is a great activity to demonstrate how sound waves travel in waves, much like ripples in water.
Materials:
- A large bowl of water
- A small stone or pebble
How to do it:
- Fill a large bowl with water.
- Drop the small stone into the water and watch how the ripples spread out.
- Explain that sound waves work in a similar way—when something makes a sound, it causes vibrations that spread out in all directions like ripples.
This visual representation helps children understand that sound waves, like water waves, move through a medium (air, water, etc.). For more details on sound movement, check out our blog post What is Audio Wavelength? to understand how wave length impacts sound.
2. Tuning Forks and Water
Using a tuning fork and water can be an exciting way to show children how sound creates vibrations.
Materials:
- A tuning fork
- A cup of water
How to do it:
- Strike the tuning fork against a soft object, like a rubber mallet or your hand, to make it vibrate.
- Quickly dip the tips of the vibrating tuning fork into the water.
- Watch as the vibrations cause ripples to appear in the water.
This demonstrates how sound vibrations create waves that we can’t see in the air but can visualise through the water. It's also a fun way to combine sound and sight!
If your child is curious about what causes sounds to have different pitches, explore What is Audio Frequency? for an explanation on how sound frequency works.
3. Rubber Band Guitar
Making a rubber band guitar is a simple and creative way to show how different sound waves create different pitches.
Materials:
- An empty tissue box or shoebox
- Rubber bands of various thicknesses
How to do it:
- Stretch different-sized rubber bands around the box so they cover the open part.
- Pluck the rubber bands and observe how each band creates a different sound.
- Explain that the thicker rubber bands create lower-pitched sounds, while thinner bands produce higher-pitched sounds.
This is an interactive way to teach children that the size and tension of an object affect the sound it makes. You can dive deeper into the connection between tension and pitch by reading What is Audio Amplitude?.
4. Paper Cup Telephone
This classic experiment is a wonderful way to introduce children to the concept of sound waves travelling through different materials.
Materials:
- Two paper cups
- A long piece of string
How to do it:
- Punch a hole in the bottom of each paper cup.
- Thread a piece of string through both holes and tie knots to hold it in place.
- Stand apart and pull the string tight. One person speaks into one cup while the other listens at the other end.
The sound of your voice travels through the string as vibrations, making this a simple way to teach how sound waves move through different materials. It's a great way to illustrate how sound can travel through solids!

5. Sound Wave Dance
This is a fun, active way to help children understand how sound waves move.
Materials:
- A large open space
How to do it:
- Explain that sound waves move in patterns and travel through space.
- Have the children form a line and hold hands.
- The child at one end will begin by moving in a wave-like motion, passing the movement down the line to the other children.
This activity demonstrates that sound waves travel through air in a similar way to how the "wave" travels down the line of children. It’s a physical way to help kids visualise and feel how sound waves move!
Final Thoughts
Teaching primary school children about sound waves doesn’t have to be complicated or dry. By turning these concepts into hands-on activities, you can help them understand and enjoy learning about the science behind sound. Plus, these experiments and games make it easier for kids to grasp complex ideas through play.
If your child enjoys exploring the wonders of sound, our Science of Sound holiday camps offer a range of fun, hands-on science activities that make learning exciting. Find out more about our upcoming camps and programmes here.
