We launched rockets that we made from scratch. We built and designed them. I was surprised to see the height it went. Our team worked together on building the rocket, and we were hoping that it would pay off and our rocket will launch really high into the sky. I learned that if you don’t work as a team, your rocket won’t go as high because not everyone’s work would be in the rocket and you have one less person to help you build it. Also you should not talk to your friends instead of helping because then you can say it is your rocket, but only you would no it is not really because you did not help.

 

For the launching part, we got our rocket ready by pumping the pumper to fifty so it had enough air pressure and they started counting down. I was hoping that it would go really high because we worked on the rocket for a while, and it would be sad if it did not even get off the launch pad. When they got to 1 the rocket launched of the launch pad. I thought it would go high but it did not. It went low compared to everyone else’s rockets but at least it got off the launch pad. When everyone else’s came down, they were all really happy and ran to get it. Our group did too, because even though it did not go as high as everyone else’s, it still went high. 

 

I think our group will change the fins because they were really big and I think that that added to much weight and also I think they took up too much space and the air slid down the side of the rocket too soon but if the fins were smaller they would be lower down so the air would not slide down the sides till about a half a second later which might help. Also all the groups whose fins were small got really high so maybe if our group does that, our rocket will go higher than it did in the first rocket launch.

 

I think our rocket group did good because even though our rocket did not go very high, it still got off the launch pad and our work paid off because it worked pretty good and in the second launch, I hope it will go even higher!

Designing and Builded Rocket

 

For the design of our rocket we chose the nose cone to be sharp so that it can cut through the air easier and it can create a path for the rest of the rocket to go through. We choose the fins to be a triangle so the air can slide down the sides. We choose a thin rocket so it can be less weight. We wanted to do the fins with styrofoam so they are sturdy and they can not really flop over like cardboard. We decided to cover almost everything with tape so that everything is more sturdy but we did not want to add too much tape to the rocket so it is less weight and it will get off the launcher.

 

When we were building our rocket, our group did not agree on a lot of things like what tape we were going to use. Our inspiration board helped us because we wrote some materials that we would use so we looked at that. When we were building our rocket, we all wanted to do everything on some things that only one person can do, that the fin templates and taping the rocket. We agreed on somethings though, like how big the fins will be. Sometimes two people wanted something but the other two people wanted something else, so we had to sometimes compromise, and sometimes we had to pick the best way to do it.
