In class we had a demonstration of evaporation. The problem was to determine what happens to something that is mixed with water when the water evaporates. Does the stuff mixed in the water evaporate too?
I took water and added food coloring in one container and salt in the other. I heated the water and evaporated it out of the container. The students looked at the containers and noticed something was left behind. What does this mean? What was left behind?

Dear Mr.C's class,
We are also lerning about the water cycle. Evaporation is Kaylie's favorite while precipitation is Kasi favorite. Maybe sometime you can visit our class blog at http://lipskymatthews.blogspot.com
Sincerely,
Kaylie and Kasi
