Life in the Pond: Sink or Float?

** I receive curriculum from Experience Early Learning (formally known as Mother Goose Time) for honest and authentic stories resulting from my daily experiences using the curriculum. This is my 5th year using Experience Early Learning, and I am pleased to promote quality educational learning experiences through play with Experience Early Learning.

This month we played a game called, “Sink or Float?” This ideas was one of Experience Early Learning’s steam stations. And my students absolutely loved it!

First, we talked about what it means when something sinks in water and what it means when an object floats in water. I wrote the words on the whiteboard. I had the students identify the first letter in each word. Then, each student wrote down on a piece of paper an “S” on one side for sink, and an “F” on the other side for float. Before we dropped an object in the water bucket, the students made a guess as to whether they think that object would sink or float in the water. It was interesting to hear why they made the choice that they did. I’ve got some thinkers in my class!

I wanted to make this a hands on experiment, so I had each of the students grab one item from the classroom that they could drop in the water. They were all so excited that they were going to be able to put something in the water. We made our guesses and a few people told why they made that choice before we dropped each item in the water.

In small group, we did another water activity that also had to do with objects sinking and floating. It was a little different, and the students loved it! We had two bins filled with water. Each bin had a plate floating on the top. The students took turns rolling the cube, identifying the number they rolled, and counting out that many duck counters to put on one of the plates. They repeated the process, but put the new set of ducks on the second plate. We compared plates. Which one had more ducks? Which one had the least amount of ducks? If I add the ducks together, how many will I have? After everyone got a turn rolling the dice and comparing the numbers, we carefully took turns counting the ducks and putting them on a single plate one at a time. Our goal was to see how many ducks we could get on one plate before the plate got too heavy and sank.

These are two fun activities that students could easily do at home with their families.

Next week, we will be learning about insects that live near ponds. Some of these insects you may have even seen in your own backyard!
