Cool it off!
Observations
When things are heated, they become hot. When heat is taken away, they
cool down. Some things cool quickly, others cool more slowly.

Jeffrey baked some cakes in a very hot oven at 180&deg;C. He took them out of
the oven and left them to cool. After ten minutes, he stuck a thermometer
inside each cake. Place a check mark (✔) in the box by the cake that cooled
the quickest.

Record the temperature of just-prepared Jell-O every 30
minutes, until it becomes solid. How does the temperature
change?

The child will learn that some things cool down
more quickly than others. Have the child make a data
table to keep track of the Jell-O’s temperature
change. (This is an opportunity to learn how to take
temperature.)
