The grade 2's learned about liquids, solids and gases. They had fun playing with bubbles and mixing materials together. They learned that salt makes ice melt and also lowers the temperature of the solution. They learned about temperatures above and below zero and that when a liquid is brought below zero it will freeze, become a solid and expand.
My apologies that there is no picture... the pictures I took all have students in them, so I'm unable to post them here.
