Preschool Science Lesson: Sink or Float?

Sink or Float?

One afternoon we did a fun and easy science experiment. It kept both girls entertained for quite a while. They would have kept playing but I needed to get it cleaned up so I could start dinner.

If you would like to try this you will need:
A large bowl of water (this would also be fun to do in the bath!)
Things from around that house that can get wet!
Towels to clean up the mess ;)


First, I sent Grace on a hunt! Her task was to find things that could get wet but they could not be bigger than her fist.

These are some of the things she found - blocks, toy food, paper clip, straw, toy people, foil ball, silicone cupcake liner, straw, balls.

Before she put them in the water she had to guess (make a hypothesis) as to whether the object would sink or float. She did pretty good but some of the things surprised us!

Some things would float and then fill with water and sink (like the cupcake liner or lego block). And then she saw that the ball floats and the plastic grapes are made similar to the ball so the grapes will probably float. Great logic! 

And our favorite was the Dora from her Dora block set. Her head floated but her feet and legs sank she she was walking on the bottom of the bowl!

It looks like the girls are having a good time learning. And I hope that's warm water! It's too cold to be wet.
