In this experiment, we are going to wrap cups in different materials to see which one is the best at keeping Guzzler's drink warm. We will pour hot water into each cup and measure the temperature every 30 seconds for 3 minutes.

Before you start the experiment, you need to gather all the things you'll need. These include a kettle, three cups, sellotape, a tea towel, tinfoil and yourself!

To prepare the experiment, wrap one cup in tinfoil, another in the tea towel and leave the last how it is. This one will help us make sure that the test is fair.

Pour the hot water into the first cup and start the timer. Don't forget to take the temperature every 30 seconds!

Repeat the same process with both of the other cups. Make sure that the water starts off at the same temperature in all three tests to keep it fair.

Put all the data that you collected into a graph or chart to help you make sense of it.

The cup that kept the water the warmest had the best insulator.
