    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 dont 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?
