Hydro-Power

We are learning about Hydro-Power
Hydro-Power is from the mountain that goes to the river then it goes first in a intake then it goes to penstock then goes back to the river and then goes to a turbine then it turns into a generator.The generator is in a power house that the generator goes into the Long Distance Power Lines .
We made a water turbine.
First we prepared the things we need and it was 2 Small Paper Plates,Empty egg carton,Stapler or Tape,Pencil and Scissors.
Then we have make it the first step was punch a hole in the middle of each plate
Next was cut five individual cups from the egg carton.
After we sandwiched them between the two plates by stapling to the 
other side of each cup.
After that put the pencil through the center holes.Tape the plates to the pencil so that wheel makes the pencil spin.
Finally its time to test your water wheel already you can have a  friend to hold the ends of the pencil.
