power a heater and so on.P. 10
11. 1. We will always need energy. Power plant burn the coal
and oil to make electricity which provides the energy to power a
heater but they are not renewable resources. However, water is
renewable resource can replace over time. 2. This experiment is
useful because using water wheel can reduce the amount of fossil
fuels needed in electricity. It is a renewable resource and will
not be used up. It also does not product air pollution. Air
pollution might affect our health and cause lung cancer.P. 11
