Science truly surrounds us even in the sounds we hear! Kids love to make noises and sounds and it’s all a part of the physical sciences. This water xylophone sound science experiment is truly a must do classic science activity for young kids. So simple to set up, it’s kitchen science at it’s finest with plenty of room to explore and be playful with it. Homemade science and STEM is a treat for curious minds, don’t you think?

HOMEMADE WATER XYLOPHONE SOUND SCIENCE EXPERIMENT FOR KIDS

Make a homemade water xylophone sound science experiment for kids. A playful way to explore the science of sound with an easy kitchen science experiment and DIY water xylophone activity.

EASY SCIENCE TO EXPLORE

Have you ever heard of the phrase kitchen science? Ever wondered what it means? It’s probably pretty easy to guess, but I will share anyway! Let’s show our kids how cool it is to play with science.

Read more below on how you can extend this sound science experiment, add in the scientific process, and create your own sound science experiments.

Kitchen science is science that can come out of the kitchen supplies you have! Easy to do, easy to set up, inexpensive, and perfect science for young kids. Set it up on your counter and go!

For several pretty obvious reasons, a homemade water xylophone sound science experiment is the perfect kitchen science! All you need is mason jars {or other glasses}, food coloring, water, and set up chopsticks or even a spoon or butter knife.

HOMEMADE WATER XYLOPHONE SUPPLIES

  • Water
  • Food coloring (we used blue, yellow and green for varying shades of green)
  • Wooden sticks (we used bamboo skewers)
  • 4+ mason jars

 

Making Water Xylophone Supplies for Sound Science Experiment

SETTING UP WATER SCIENCE ACTIVITY

To get started, fill the jars with varying levels of water. You can eyeball the amounts or grab the measuring cups and get a little more scientific with your exploration.

More water equals lower sound or pitch and less water equals a higher sound or pitch. You can then add food coloring to make different colors for each note. We made our jars pure green, dark green, blue-green, and yellow-green!

SCIENTIFIC PROCESS: Make sure to have your kids tap the empty jars first to get an idea of the starting sound! Have them predict what will happen when they add water. They can also create a hypothesis surrounding what happens when more or less water is added. Read more here on the scientific process for young kids.

 SIMPLE SOUND SCIENCE WITH A WATER XYLOPHONE?

When you tap the empty jars or glasses, they all made the same sound. Adding different amounts of water changes the noise, sound, or pitch.

What did you notice about the amounts of water versus the sound or pitch that was created? The more water, the lower the pitch! The less water, the higher the pitch!

Sound waves are vibrations that travel through the medium which in this case is water! When you change the amount of water in the jars or glasses, you also change the sound waves!

EXPERIMENT WITH YOUR WATER XYLOPHONE 

  • Does tapping the sides of the jars make a purer sound than tapping the tops of the jars?
  • Try adjusting the water levels to create new sounds.
  • Try using different liquids and compare results. Different liquids have different densities and the sound waves will travel differently through them. Fill two jars the same amount but with two different liquids and observe the differences!
  • Try using different tools for tapping the glasses. Can you tell the difference between the wood chopstick and a metal butter knife?
  • If you want to get super fancy, you can use a tuning app to raise or lower the water level to match specific notes. We tested out this one a little bit although we are not music experts over here, it’s a fun way to take the experiment a step farther for older kids.
