Investigation on the effect insulation has on retaining heat
List of Equipment Needed For The Investigation:
Before beginning this experiment we predicted that the insulated cup will retain more heat and the water in this cup will stay hot for a longer period of time.
Fill Kettle with water and boil
Label plastic cups 1&2
Using the scissors provided, cut up pieces of cotton wool and bubble wrap and wrap them around plastic cup one, and secure them with sellotape
Pour the same amount of water into one insulated plastic cup and one non-insulated plastic cup.
Record the initial temperature by reading the thermometer.
Over the next 6 minutes record the temperature of the water in each cup and observe the results.
Once the 6 minutes are up, compare the different temperatures.

Place thermometers in each cup
Watch as temperatures increase and decrease
After completing this experiment we recorded our results on a graph.
