The Preschooler

Sink or Float

Bathtub time can often be a stressful time in our house.  It drives me crazy when water is being splashed onto the floor in quantities large enough to sink a small boat.  I tend to lose my patience when I am required to change my own clothes when I had not intended to take a shower while fully dressed.

However, I have also realized that this free-play time in the water is loaded with opportunities for learning and discovery.  They may not even realize they are doing it, but simple bathtub toys allow them to explore many different concepts in science.  The next time your child is bathing in the tub, conduct an informal experiment where your child will learn about sinking and floating.

Before allowing your child in the water, begin by gathering various items from around your home that are water safe and either sink or float.  Items could include some of the bathtub toys you already have, such as a plastic boat or a rubber duckie, along with items from other areas of your home such as a metal spoon, wooden spoon, or a colander.

As you place each item in the water discuss what happens.  Then, have your child predict what will happen with other items before you put them in the tub.  Ask why she chose her prediction?  Discuss shape, weight (in terms of light and heavy), and even the holes in the colander.

This can be repeated as many times as you wish using different items.  You may even draw her attention enough that she will stop trying to sink your bathroom.  And, if not, at least she will understand why it happened!
