Testing our helicopters

We each made a paper helicopter. We had to do a fair test to see what would make the helicopter fly taste to slower. We were only allowed to change one thing each time we tested it. We tried removing the paper clip, folding the wings in a different direction and opening it out to a Flat piece of paper. We found it dropped more slowly if there was a wider piece of paper. This is called wind resistance. It is a type of force.


  1. This looks like it was great learning and fun.

  2. This was a good description of the fair test. It looks a load of fun as well!
