WHICH HAS MORE DENSITY?

  

The students really like this demo!

Find 2 identical boxes. 
(See through is better so they can see what is inside)

Fill one box with feathers and one with lead shot.
(Two 25 lb bags from Cabella's fit in the shoebox size one above)

Ask students to lift each box. The difference is AMAZING!
