Purpose Hypothesis Materials Procedure Observations Conclusions Big Idea
To understand how water can make energy, I am going to test it, see it and examine it!
Purpose
Hypothesis
I think the water power will be stronger than man power and wind power!
Materials
1 Soda bottle 1 Plastic bottle 4 Wooden chopstick 15 Tooth pick 2 cork 1 Metal bar Glue gun, Tape and scissor
Procedure1. Cut the soda bottle into three pieces2. Cut the middle section into eight pieces and
become eight blades3. Push all the blades into a cork and become a
mill4. Cut the plastic bottle into two half and use the
bottom part for the base5. Insert a metal bar just below the rim of the
base and also in the middle of the mill6. Wrap a thread round another cork and insert
into the end of the metal bar7. Attach a clay to the end of the thread8. Glue the chopstick and the tooth pick to
stable the metal bar
