Wind power - Hurumanu

Aim: To learn about the rate that different materials decompose. 


Image result for test tube rack



Hypothesis: I think that the bread will decompose first because it is the most easy-its to brake down.   

Materials:

  1.   Schott Duran
  2.   cardboard 
  3.   strip of a plastic cup 
  4.   3 coped bananas 
  5.   test tube rack 
  6.  Styrofoam  
  7.   strip of bread 
Steps:
  1. put the bread in the test tube   
  2.  put the banana in the test tube 
  3.  put the paper in its test tube 
  4.   put all of four test tubes in the test tube rack
  5.  put the Styrofoam in the test tube   
  6.  pure a small amount in to the bread 
  7.  and put somewhere where no one will touch it or brake it

Conclusion: 
Field, the Anemometer spun 80 spins per minute. It had a wind speed of 13-20 kph. This speed is 3 on the Beaufort Scale. (Leaves and small twigs in constant motion; wind extends light flag.)


The old J Block site, the Anemometer spun 60 spins per minute. It had a wind speed of 13-20 kph. This speed is 3 on the Beaufort Scale.

Grass Hill in the squad, the Anemometer spun 40 spins per minute. It had a wind speed of 2-5 kph. This speed is 1 on the Beaufort Scale. (Shown by direction of wind smoke drift, but not by wind vanes.)

Tennis Court gate, the Anemometer spun 12 spins per minute. It had a wind speed of 2-5 kph. This speed is 1 on the Beaufort Scale.

According to the data, the most spins on the Anemometer is on the field, with 80 spins per minute and it had a wind speed of 13-20 kph. The least spins on the Anemometer was by the Tennis Court gate, it spun only 12 spins per minute. It had a wind speed of 2-5 kph.
