Science Experiments for Toddlers — Sink or Float? (With free printable!)

I’ve had this one on my mind for a while, and after seeing the way L was interacting with the objects I put in her water sensory bin, I knew it was finally time!

We love water works over here — the opportunity to get wet is more than L can resist, and I figure if she’s going to do it anyway I might as well make it educational.  This is our first “science” work, and it’s a hit!

I set up a tray with a bowl full of objects, a sorting chart, and a clear bin full of water.

[I do not keep the bin full of water when it’s just on the shelf — it is very heavy, and N is starting to be able to reach up that high!  I fill it when L asks for it.]

Before we started, I explained the chart to L.  She can’t read yet (she’s only 2!), so I included simple pictures to go along with each category.  I showed her that the triangle on the first side of the chart falls to the bottom of the bin — it sinks.  The triangle on the second side of the chart stays on top of the water — it floats.

When she was finished, L got a washcloth to dry up the water all over the tray and chart.

This is a great first science experiment for young children, as well as an introduction to opposites!

{I laminated mine so it doesn’t get ruined by the water.  If you don’t have a laminator, you can try putting it in a sheet protector and sealing the open end with clear packing tape.}

  1. I have to try this with my 2 year old. Is always hard for me to figure out activities to do with him. As a teacher I want to make sure he is ready for school but since I teach middle school sometimes I am out of touch with what appropriate for his developmental level of learning. Thanks a lot for this idea.
