Will it Float? Simple Science with Prediction Chart

Will it float or sink?  My boys had so much fun gathering and testing different objects to see if they would sink or float when placed in water.  Their guesses were not always accurate.

Simple Science: Will it Float?

I love simple science projects that even my youngest scientists can enjoy.  This week’s simple science project we named, “Will it Float?”  We started by having my two youngest boys go throughout the house and find items that they wanted to test in the water to see if they would float or sink.

Will it floatSome of the items they gathered included a banana, penny, toy ring, fork, washcloth, rocks, marbles, bath toy, crackers and a Weeble.   We made predictions as to what would happen, filled a pitcher full of water and let the boys drop them in one by one to see if they would float or sink.

Will it floatI asked my 5-year-old to describe why he thought some things float and some things sink.  His answer was, “Some stuff is really heavy and some has air in it so it can float.”  We talked just a little bit about density and how an object that is more dense than the water will sink and one that is more dense will float.  We also noticed that the washcloth floated on the top for just a few seconds before it soaked in the water and then it sunk.

I’ve put together a simple prediction chart that you can use when doing this experiment with your kids.   You can get it here: Will it float-Prediction Chart

What types of objects will you try?
