1) The document describes a student experiment to test the hypothesis that water power is stronger than human power or wind power. 2) The student builds a water wheel from recycled materials like bottles and uses it with flowing water to spin a generator, recording the power outputs. 3) The results support the hypothesis, showing that water power generated continuous force and a higher power output than human or wind power, demonstrating water's ability to be harnessed as a renewable energy source.

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
POWER POWER POWER
12’S 10’S 4’S
Man Power: Cannot give continuous force to the turbine
Wind Power: Cannot give the full impact of the force to
the blades
Water Power: Can give continuous and more impact of
the force to the blades

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

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

14. The Hydro power is something using water to
transform the power into electricity!
The bad thing about Hydro power:
It is because when you make
 It’s hard to find the right Hydro power, you need to build
place and it will destroy a dam. When you build a dam the
you will need a big and wide
the local habitat place to build it and there have
no salmon laying eggs. But that
not all, you also need to tell the
ones that is living near the river,
because the water will rise!

15. No
pollution

16. THE END
