For our next science unit we will be studying sinking and floating. As an introduction to our unit I picked up a couple of preschool science books from the library. I was surprised to be able to find such great storybooks on the subject of science for preschoolers that explained topics at a preschool level.

The first book I came across was Captain Kidd’s Crew Experiments with Sinking and Floating by Mark Weakland. This is a fun book perfect for preschoolers that teaches all about density and buoyancy through the pirate characters in the story.

The second book that I found and really liked is What Floats in a Moat? by Lynne Berry. It’s a humorous story about a goat and a hen using trial and error to try to get across a moat without using the drawbridge. 

Over the past week, I read Caden these two books and did an sink/float experiment based off of Weakland’s book. I gathered the objects tested in the book and in some cases had to substitute objects (no cannonballs here). 😉 Then I set up the experiment at the kitchen table.

Caden 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 the objects on his own, this time I handed him the objects one at a time and asked him to predict whether the object would sink or float. 

First we tested the “cannonball” aka bouncy ball. A marble would have also worked, but we don’t have any marbles. We tested the rest of the objects, I spare you from picture overload, and then I let Caden play with the water, further exploring the objects how ever he wanted.

These children’s books are a really fun way for preschoolers to learn about science. And this is a really fun way to explore sinking and floating with preschoolers. I am looking forward to our next science experiment and learning about sinking and floating along with Caden.

And now it’s time for the Saturday Science Blog Hop!
