Matter Changes

We've been learning about how matter changes. On Wednesday morning we put water in a plastic container and drew a black line to show the water level. We put the container in the freezer and then looked at the container at science time. The students noticed that the water turned to ice and when we drew the red line we noticed that the water expanded. We had a great discussion on how water changes.
We talked about evaporation and condensation too. The students washed their desk tops and noticed that in about 1 minutes the wet surface was dry. They watched the water evaporate into the air. Our next activity was to see condensation so we added ice cubes to the blue water and waited for the glass to "sweat". We had a lot of great discussions about how water changes from a solid to a liquid and to a gas.
