Sound Science Experiments for Preschoolers

We’ve been studying music in our home preschool. The natural thing to explore during science time??? SOUND!

Check out these simple science experiments that helped us explore sound. 

 

Supplies: 

Three bowls of varying sizes

Three jars of the same size

Sugar

Water

Metal Spoon

Plastic Cling Wrap

Directions:

Start by covering the three bowls with cling wrap. My son immediately started drumming on them. We discussed the different tones coming from each drum and way that might be the case.

I wanted my son to visual how sound is really a wave vibrating. So first I tried placing rice on the top of the drum. The rice certainly danced when we drummed on it, but it didn’t move when we just used our voices.

So I switched to sugar.

Oh man did those little guys hop when my son and I hummed! It was so exciting to see the concept click in my son’s head!

 

After that, we switched to the jars. Loopy was very surprised to observe that the jars, though the same size, made different noises because of various water levels! I let him take the lead in this as he poured and emptied jars, trying to get the sound he was looking for.
