Our group changed the fins of our rocket because most other groups fins were small and went really high. That made our group thought that if we make the fins smaller, our rocket will go higher than the first launch. Also small fins would make the rocket lighter so that would also make it go higher than the first launch.

When we designed our second rocket some things went well and some things did not.. What went well was our whole group agreed to change the same thing right away. We all had the same idea, so it was really easy to decide what we were going to change on our second rocket. What did not go that well is our group also wanted to change some other things, like the nose cone. We can only change one thing though so we desighted right away that we were going to change the fins.

What went well with building our second rocket is we built the body fast, so we had more time to make the things that were harder, like the nose cone. We were able to do that longer, so it is better. What did not go well, is we did not all agree on the fins and which ones we were using. Someone thought we should not use the fins I made and we should use the ones they made. We ended up using both.

We collaborated on our design. We also took the time to collaborate on our fins because we smoothed them out to make them even. Also because we did not want our rocket to be really bumpy when the rocket is going up in the air. Our group compromized when we disagreed. When we did not agree on the fins we used both fins that both people made.
