The Water Cycle: Free KS2 Science Worksheet (Ages 8 to 10)

What your child will learn

This worksheet supports the Year 4 Science statutory requirement to identify the part played by evaporation and condensation in the water cycle. Children name the four key stages — evaporation, condensation, precipitation and collection — and describe how water moves between the sea, the sky and the land in a continuous loop that never runs out. The colouring element gives them time to study the landscape closely, while the writing tasks check that they can use the correct vocabulary and explain the underlying changes of state, rather than simply labelling a picture from memory.

Understanding evaporation and condensation

The two processes children most often confuse are evaporation and condensation, so this worksheet keeps them side by side. Evaporation is when liquid water gains heat from the sun and turns into an invisible gas called water vapour, rising into the sky. Condensation is the reverse: as the vapour rises and cools, it turns back into tiny liquid droplets that gather to form clouds. A common misconception is that clouds are made of steam or water vapour; in fact vapour is invisible, and clouds are millions of tiny drops of liquid water (or ice). The curriculum also links temperature to the rate of evaporation — the warmer it is, the faster water evaporates, which is why puddles vanish more quickly on a sunny day than a cold one.

How to use this worksheet

Print the sheet at A4 and let your child colour the landscape first — blue for the sea, river and rain, grey or white for the cloud, yellow for the sun — using the colour suggestions as a guide. Talk through what is happening at each part of the picture as they colour, then move on to the writing task. Encourage full sentences in the answers; saying ‘the sun heats the sea and the water evaporates’ shows deeper understanding than a single word. For a quick extension, ask where the cycle ‘begins’ — a useful prompt, because the answer is that a continuous loop has no true beginning or end.

Ways to extend the learning

The water cycle suits hands-on follow-up. A clear bowl of water covered with cling film and left on a sunny windowsill will show droplets of condensation forming on the underside within hours — a miniature water cycle children can watch. You can also link the topic to weather, rivers and the local environment in Geography, or revisit the wider idea of states of matter (solid, liquid and gas) that underpins the whole unit. Comparing how quickly water dries in warm and cool spots makes a simple fair test for the temperature objective.
