Matter Experiments

Our most recent science unit focused on matter.  We learned about the 3 states of matter: solid, liquid, and gas.  Our last 3 experiments focused on a property of matter: density.  This can be a hard concept to understand because it would seem that heavy things automatically sink and light things float, but we learned that is not the case because of density.  We defined density as the amount of atoms that are packed into a given volume.  The more atoms packed in, the more dense.  We experimented with sink and float,  rainbow in a jar which was a layering of liquids from most dense to least dense, and using salt to affect the density of the liquids.  We had a lot of fun with these experiments!
