Sink float water science is filled with many learning opportunities!

We used items straight out of the kitchen for our sink float water science activity. Grab different fruits and vegetables, aluminum foil, aluminum cans, spoons {both plastic and metal}, sponges. You could also test peeling your vegetables or slicing them. Plus I am sure your child will be able to come with other fun things to test! This is so simple but very engaging for young kids. He loves to get his hands right into our sink float water activities.

Water sensory science experiments and activities really engage the senses.

Can you make the sponge sink? Also check out our easy water absorption activity with sponges.

A couple of interesting things we tested in our sink float water activity were the aluminum can and aluminum oil. We noticed the can floats, but when pushed under will sink. We could see the air bubbles coming out that helped it to float. The aluminum foil floats when it is flat, when it is crippled into a loose ball and even a tight ball. However if you give it a good pound to really flatten it, you can make it sink. Removing the air will sink it.

Sink float water science doesn’t just have to be in the kitchen. Take it outdoors and use natural items. Try out favorite toys. The possibilities are endless and young kids love water play.
