Sink or Float?

Mission:  To see what objects sink or float.

The scientist in my classroom performed an experiment to see what items would sink or float.  The results were staggering!!!!

Before my little scientists could begin their experiment they had to learn a few key concepts to develop an understanding of why some items sink and some float.  We discussed what the words heavy and light meant, and predicted what objects on the chart  (MacMillan McGraw- Hill) pictured above would sink or float.  

Each pair of scientists were given a tray with a tub of water and different objects to experiment with.
They recorded their observations of the worksheet pictured above.  

At the end of the experiment I encouraged my scientists to freely explore the objects.

We wrapped up our experiment by watching a BrainPop Jr. titled Sink or Float.
