My Fair Test Investigation

Ruled paper

Step 3 : Collect up the data until the temperatures are equal again, and see which insulation has cause the temperature to drop quickest, and which has caused the slowest drop.

In this experiment, we wanted to find out if wrapping a cup of water up in different materials, would change how quickly the water would change temperature.

Wrap each of the 3 paper cups in a different material, and secure with tape.

I found that in my experiment, the fabric cloth was the best insulator, and the water in the cup with no insulation dropped in temperature quickest.

- 3 Paper cups - 3 Thermometers - Kettle - A Jay-Cloth - A Fabric Cloth

Step 2 : Add 50ml of boiling water from the kettle into each of the insulated cups. Use a thermometer in each to measure the temperature of the water at 20 sec. intervals.
