Science: Sink or Float Experiment

In this simple science experiment Caden tested various tool related objects to determine whether they sink or float. This was Caden’s first science experiment! He had such a fun time that he cried when it was time to clean up. But I’m sure that had more to do with playing with the water than the science experiment.

To set up this activity I first placed a bath towel on the kitchen table, I then added a small bin of water only about half full. Then I put the test objects (nuts, bolts, screws, nails, screwdriver, sawdust, block of wood) which I collected from Daddy’s tool box next to it. Some of the objects I used are small or pointy, please make sure you carefully watch your child during this experiment. I would also make sure you have a count of each object, so you don’t leave any behind after cleaning up.

Caden quickly placed each object in the water. With each object I asked whether it sank or floated. I think after a few tests Caden understood the difference between sink and float.

After Caden tested all the tool related objects, he tried out other things. Such as the silicone cupcake liner and a plastic bowl.

Then Caden proceeded to observe the water and what happened when he dropped the wood block or tapped it with the screwdriver. He had a lot of fun making waves and splashing in the water and it was a great way to pass the afternoon.

This is the third post in my Tools unit series. We’ve had a lot of fun learning about tools. Check out what we have done so far:

    What a cool way to work tools into a science experiment! I know both my little ones would get a kick out of this. So glad you linked up to Discover & Explore this week!

    […] was already familiar with this type of experiment from the first time we did it about a year ago, and he really loves doing them. But instead of just letting him explore […]
