Paper helicopter

Week 6:                      paper helicopter.

This week we started our flight rotations. We built a paper helicopter. We used a tutorial on how to build it. My friend Tyler and lily also made me a paper helicopter. 

It went ok because I had a race and i dropped them to see whose would spin the longest. Lily won the competition.

When you drop it, it twirls around and around in circles and it's really cool to watch. I think it was twirling because of the force weight. 

I wonder if i made it from cardboard, whether it would go down quicker because it is heavier. 

I am multi-structure because i know how to  and inference and a gathering data. I know a lot about flight and i know the four forces. They are weight, drag, lift, and thrust.
