Wind Racers
How my group worked together
I think that my group worked quite well considering the fact that there were only two of us, which were myself and Shikobi.
How successful our wind racer was
Our original one worked better than the one with changes.
How I found this activity
I found this activity quite interesting and fun at the same time.

My group didn't really do much research as we already had a fair idea of what we were going to do. However, we did come across a pirate ship looking design to create.
Design
The design we had chosen was the pirate looking one as it looked interesting and was more appealing than the average triangular shaped one. The design was a square which had curves in places.

Build
The sails were made of newsprint and cardboard. Our sail was attached straight onto the metal rod with tape. Each of them were placed evenly at the bottom and top of the rod.

Test
We went outside to race them. We used a leaf blower. Our first try went 70cm.

Redesign/Make Changes
The changes we made were to the bottom sail. We changed it because it was stiff and didn't help as much as we thought.

Test
Our second go didn't go as we planned as it completely failed because it didn't have enough support in the bottom sail.

Evaluate
Overall our original sail worked better than the second one. However, we could have added less cardboard to our original design so it wouldn't be too light or heavier than it was in the first place.

Great work Nelly, next time it would be awesome to include some detail in your evaluation and changes to explain why you made the decisions you did, eg. why would you have less cardboard? what would it do?
