Answer :

The water cycle is one of the important natural cycles. In the water cycle water goes into the atmosphere in the form of vapours from the water bodies such as ocean, rivers and comes on the earth as liquid water as rain.

Let’s try to make a model of water cycle which may useful in helping you to understand the process.

Materials required:

A large zip-lock plastic bag, water, food colour, masking tape and a thermometer


i. Put about 250 ml of water into the bag. Add a drop or two of food colour.

ii. Now close the bag and fixed the bag on the window which is receiving sunlight.

iii. Hold the bulb of the thermometer against the bag for three minutes and then record the temperature.

iv. Let the bag hang in the sun for 3-4 hours then observe the bag again.

v. Look for any changes in the bag. Small water droplets will appear on the side of the bag and the level of water goes down.

vi. Hold the bulb of the thermometer against the bag again for three minutes. Record the change in temperature.


Small water droplets on the wall of the bag is due to evaporation and it will condensed to water. Thus, shows water cycle.
