The Hoggatt Institute of Math and Science at Neosho Christian School was really busy, last week, experimenting with density. The first pictures below show students collecting different colors at different levels in a straw by using a variety of salt levels. Students were amazed with the results, and it was one of those times when the teacher could see the light come on above their heads as they realized their success.
Earlier in the week, Mrs. Hoggatt did a demonstration of density using the following media, listed in the order of increasing density and pictured from top to bottom:

The next step was to insert solid objects - bolts, a game die, popcorn kernels, beads, and a ping pong ball - to the mixture to see at which levels they would land. They settled where their densities determined they would.
