Experiment on solar energy stove

　　Today we spend the break in the noon doing an experiment to show that the water boils on the solar energy stove as quickly as on the ordinary stove to call on people to use solar energy stove which does not pollute the environment. We borrow the thermometer, teapot and water from our teachers. We also design a table to record the temperature of water.
　　In the beginning, we put the teapot on the solar energy stove and then wait. Five mimutes later, we record the temperature of the water. Our teacher corrects our gestures. Then we record the second and the third temperatures of the water. Unexpectedly, it takes 30 mimutes to boil the water on the ordinary stove while only 15 minutes on solar energy stove which not only saves the fuels but also the time. This experiment not only improves our ability to practise but also makes us pay attention to the solar energy stove. There are limited resources on Earth, so we should protect the resources, protect our hometown and protect the human beings ourselves!
