Denser – the molecules of an object are closer together.
Less Dense – the molecules of an object are not as close together.
Everything in the world is made up of molecules. How close together the molecules are determine the objects density.
I now pronounce that all of you are molecules!
Stand up!

What will happen when you drop a rubber stopper in the cup of water?
A wooden bead?
A cork?
A penny?

If an object floats in water, the object is less dense than water.
If an object sinks in water, the object is denser than water.
Which objects are less densethan water? Which objects are denser than water?

Getters need to get a tray with a small vial, a craft stick, and a rubber band.
Starters will get the cup of water.
The Encourager will assemble the vials on the sticks and practice lowering the empty vial into the cup.
The teacher will fill the vial with hot water that has been dyed red.

What happened to the hot water in the vials?
Why do you think this happened?
