Freezing and Melting

This week Olaf the snowman has visited Reception B. He left us a challenge to find out if different items would freeze. We chose to test playdough, ketchup, Pepsi, water,bread, jam and brown sugar. 

We found out that the liquids froze and the solids didn’t.  We also noticed that the liquids that were solid began to melt because of the heat in our classroom.

The children made ice lollies and talked about how they were  liquid at first but froze in the freezer because it was so cold in there.
