This experiment will show how water reacts to extreme temperatures of hot and cold. The equipment you will need for this experiment include:

• A small empty beaker
• A bigger beaker with ice
• A flask with coloured liquid, the tube with markings on it
• A kettle
   

Method and observations:

• Place the flask with coloured liquid in the small empty beaker
• Pour the boiling water in the beaker and let it rest for a minute. You will see the level of liquid in the tube rising
• Now remove the flask from the beaker and place it in the beaker with ice
• Let it rest there and observe the level of the liquid in the tube falling as the liquid cools
