For the second rocket, my group first struggled on deciding which feature to change. But at last, we decided on one part, and it’s fins.
We chose to change the fins because for the first launching, a group called Flying Saucers’s rocket went the highest and our group realized that their fins are so different than our rocket and we thought if we change our fins, our rocket will go higher. But we couldn’t agree on one still! So what we did was we mixed up our fins that we want for our rocket. Other groups didn’t have the fins we were going to use so we were happy about it. We also did use less tape than we did last time because we realized that the groups that went higher than our group last time didn’t use too much tape like we did. So this time, we used a little bit of tape. We didn’t change our body or our nose cone because we were only supposed to change one feature of our rocket. I think building our second rocket, we did great on changing the type of the fins. I think changing only one feature on one rocket and deciding which part was the most challenging part about building the second rocket.
