Hypothesis
If you use a non-stopping water source and apply it to a water wheel then energy will be created because the water can cause a rotation thus creating energy.
Independent Variable: Flow rate of water
Dependent Variable: Time for bolt to reach the top of the bucket
Control Variable: Water Wheel
Independent Variable: Flow rate of water
Dependent Variable: Time for bolt to reach the top of the bucket
Control Variable: Water Wheel
As you can see in this excellent diagram this is how hydropower works. The water coming from the reservoir is non-stopping thus creating energy. This energy will then flow into the generator and sent to the powerhouse. The turbine is the device that is used for sending the water into the generator. The generator then uses the water to create energy by power lines.
