Designing

When we designed our 3rd rocket we changed the fins but left the nose cone and the body the same. We changed the fins this time because for our second rocket we could only change one thing and we changed the body from the thin tube to the thicker tube, but we also wanted to make the fins bigger, so now we can have both on one rocket. We decided to keep the body size and the nose cone size the same because we think that did better.

Building 

When we built our rocket we tried to make it the same exact thing as the design so that it would be accurate to what we wanted. I feel like this time there weren’t as many mistakes, I think that is because we had a lot of experience since we did it a lot. we also made the nose cone hot glued and taped.
