THE EFFECT OF AN ICE CUBE ON THE TEMPERATURE OF WATER
Procedure:
- Observe the ice cube
- Cover 3 different cups with 3 different materials
- Take temperatures of water in the cups
- Place an ice cube in each cup
Once the ice cube melts:
- Record the temperature of the water at 30 second intervals for 2 minutes
- Record results
Observing the ice cube:
Transparent
No smell
Cube shape
Clear/ White colour
Solid
Reflective
We Predict:
The ice cube will make the temperature of the water drop
MATERIALS:
Thermometer
Ice cubes
Paper cups
Cotton wool, tinfoil, cloth
Water
Elastic bands
How to keep a fair test
. We will keep the same:
- the amount of water in each cup
. We will change:
- the material we use around the cup
. We will observe:
- the temperature of the water as the ice melts
OUR RESULTS
. We found that the cloth was the best material to keep the water warm.

. At each 30 second interval, we noticed that the temperature of the water in the cup insulated by cloth dropped the least compared to the other 2 cups.

. We concluded that cloth is the best insulator.
