Water Displacement Activity

A simple but fun activity to teach children about water displacement:

I recently thought it would be fun to do a water displacement activity with the hooligans.water displacement activity - happy hooligans

When I was young, I was fascinated by a fable called The Crow and the Pitcher, a story about a thirsty crow who knew all about water displacement.  He dropped stones into a pitcher half-full of water, to raise the level of the water high enough that he could take a drink.  

We re-created that story using a few items that we had here at home.

Items needed for this water displacement activity:

  • a clear, plastic container
  • stones and rocks
  • plastic turtle
  • permanent marker

How we conducted our experiment:

We experimented with a few different containers, and discovered that the one with the largest opening worked best.

We filled our container with water, and I marked the level of the water on the container so we could monitor our progress.

Then I hooked our toy turtle to the top of the container, and the fun began…

The children worked together, dropping the stones into the container.

They were amazed to see how quickly the level of the water rose.

And they grew more and more excited as the water rose higher.

After using up the small stones, the water still hadn’t reached the top of the container, so we got out our larger beach stones and rocks.

The medium-sized stones still didn’t do the job completely, so the children removed some of them, and experimented with the largest rocks, moving them this way and that, to get them to fit into the container.

It took lots of thought and co-operation to get it just right, and then finally…  SUCCESS!
