This document summarizes a student's experiment to test the power of water. The student hypothesized that water power would be stronger than human power or wind power. They constructed a water wheel out of recycled materials and tested it against manual and wind powered timers. The results showed that the water wheel was the most powerful, turning four times faster than a manual timer and over twice as fast as a wind-powered one. The student concluded that hydroelectric power is a strong source of energy and that more should be utilized by the government.

3. To understand how water can make
energy, I am going to test it, see it and
examine it!

4. I think the water power will be stronger than
man power and wind power!

5.  1 Soda bottle
 1 Plastic bottle
 4 Wooden chopstick
 15 Tooth pick
 2 cork
 1 Metal bar
 Glue gun, Tape and scissor

6. 1. Cut the soda bottle into three pieces
2. Cut the middle section into eight pieces and become
eight blades
3. Push all the blades into a cork and become a mill
4. Cut the plastic bottle into two half and use the
bottom part for the base
5. Insert a metal bar just below the rim of the base and
also in the middle of the mill
6. Wrap a thread round another cork and insert into
the end of the metal bar
7. Attach a clay to the end of the thread
8. Glue the chopstick and the tooth pick to stable the
metal bar

10. MAN WIND WATER

11. In this experiment, I learned that the water
power is quite strong.

12. Our government should use more hydro
power to generate electricity!

13. THE END
