Wednesday Challenge: 8th July
Make a Water Wheel
Equipment for 1 water wheel
2x sturdy paper plates
Ruler and pencil
Length of dowel longer than the width of the tub
Recycled plastic cups, pots or paper cups
Jug or watering can
To Make the Water Wheel
1. Measure and mark the centre of the two paper plates.
2. Perforate the plates with a pencil at the marks.
3. Push the dowel through the two plates.
4. Staple a minimum of three cups snugly between the two plates.
5. The cups should be evenly spaced and all facing the same direction.
6. Mark one of the cups prominently with a permanent marker.
7. Balance the wheel width-ways across the tub.
Steadily pour the water from a jug into the top cup of the water wheel and watch it begin to rotate as the water flows. Count how many rotations the wheel makes using 1 litre of water?
Make a Prediction
If you have more water, will the wheel turn more times?
