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

First we put a chocolate button into a plastic bag

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

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

Today we looked in the freezer.....

What had happened???

The chocolate was hard again

Yum, yum

 Our question.........

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

Heating and cooling changed the chocolate.

We used our 5 senses to describe what happens to chocolate when it is heated....
