Directions
Before the meeting:
Fill a 17-gallon tub with about twelve gallons of water outside.
During the meeting:
Gather the Cub Scouts and adult partners around the tub filled with water.
Explain to Cub Scouts that some things float, and some things don’t. What makes something float naturally is if it is more solid (called density) than the water. The weight of the object doesn’t matter as much as how solid it is or dense it is. Something can also float based on how it is designed. A big battleship is made out of metal but because of the way a boat is designed it stays afloat.
Show the Cub Scouts the 5 things that float and the 5 things that do not. Take each object and ask the Cub Scouts if they think it will float or sink? Once they respond place the item in the tub of water to see what happens.
