Fair Test Investigation

Why do you think Guzzler's hot chocolate keep getting cold?

What could we do to help Guzzler to keep his hot chocolate warm?

1. Cut the same amount of fabric/ material for each cup. Make sure each cup is wrapped in the same way to make sure the results are fair!

2. Fill each cup with the same amount and temperature of water.

3. Take the temperature of the water in each cup every minute for 5 minutes, and record your results.

EQUIPMENT

The tinfoil was the best insulator because the water in the cup wrapped in tinfoil lost the least amount of heat!

Guzzler will be very happy with his warm hot chocolate!
