Yesterday we did a fun experiment with chocolate......

First we put a chocolate button into a plastic bag

Next we drew what the chocolate looked like and circled on our sheet whether it was a solid or liquid.

Then we held the the bag between our hands and waited for 2 minutes.....

What is happening.........
Max said, the chocolate feels soft.
The chocolate was changing from a solid to a liquid

Finally we put the bag in the freezer. The freezer was very cold........

Today we looked in the freezer.....

What had happened???

It is hard

"It is solid and I can break it", said Arielle

 Our question.........

What changes chocolate from a solid to a liquid then back to a solid..........

Heating and cooling changed the chocolate.
