METHOD:
Step 1 – Place tub/box in a sunny position and put the cup/mug in the centre of the tub/box.(NB: a lamp can be used as an alternative to in the sun).
Step 2 – Pour water into tub/box.
Step 3 – Cover the tub/box with plastic cling wrap, securing tie edges down with tape to hold in place – but don’t make the plastic wrap too tight as it needs to dip a littlein the middle.
Step 4 – Place the small stone in the middle of the plastic wrap to create the dip in the centre
Step 5 – Leave for 3-4 hours then check on the tub/box. Record results.
AIM: To create a model of the water cycle.
MATERIALS: You will need –
• 1 plastic tub/plastic box with sides at least 30 cm high
• 1 cup/mug
• Some clear plastic wrap
• 4 cups of water (may vary depending on tub/box size)
• 1 small stone
• Some tape to hold plastic wrap to tub/box

RESULTS:
What happened in the tub/box?
In which part does evaporation occur?
In what part does condensation occur?
In which part does precipitation occur?
In which part does collection occur?
DISCUSSION & CONCLUSIONS:
Why do you think each of the four processes happened to the water in the tub/box?
What was the energy source driving these processes?
