Designing and Building and Launching Rocket #3

In rocketry we are currently building our third rocket. My team has almost finished and we are so excited for the third launch because our parents are coming.

First we designed the rocket, it took longer than expected because we were very slow and didn’t agree much. What we did was copy and pasted our second rocket and then we changed the color and nose cone because we decided the thing we were changing was the nose cone. 

Another team had a pointy tall nose cone and that’s what we wanted so we did what they did. They stacked two nose cones on top of each other. One small and one that actually fit the rocket. Then I taped them separately with black tape, to make them bigger because when I taped them together it was bigger because they already had tape on them. So I taped them with black tape nice and tight. For our rocket body it was the same, skinny and thin. We decided to make it blue with black tape. For our fins we did the same thing as the second rocket’s fins. In our group someone wanted to cut the body in half because in another class they had tiny rockets and they went 218 feet. But we used popsicle sticks and he was also outvoted. 

We didn’t work so well when deciding to change our rocket. Like when someone wanted to cut it in half so it was a tiny rocket, it became a big mess. Then our teacher came around and told him we couldn’t change it again, but he just kept picking popsicle sticks and kept pulling them out until he picked his name. It got annoying at times but in the end it was good and we always have a way to figure it out.

We also launched our rocket #3 at first my class thought we were just building it but then our teacher decided to let us launch it. Our rocket went 153 feet high! The third launch was our highest launch! We were super surprised with the results and didn’t think it would go that high. We tied with team Chicos. Their average was the highest! We were all super happy! 

At the launch, I think it was the best moment from the start of the unit because we knew it would be ending soon and we all challenged each other really well. It helped me because I never knew if we would fight or not and we did, but we always resolved it.

Launching and Graphing Rocket #2

Our second launch was also good and I was surprised that it didn’t go higher than our other rocket because when you looked up it looked a lot higher. Again I thought it would fail but of course I was wrong again which is great! I am very happy with our results. Though because the group that went the highest basically had the same design and our rocket didn’t go higher than that group’s rocket. I was confused about but it’s okay. My team job was pumper because last time I got one of the “good” jobs. But I didn’t really care because it wasn’t “boring”. I thought it was kinda fun and you got to see the pressure of the air go up! 

 

Our teams launch when we launched everyone looked up and it look like it was almost 150 feet high! I had my hopes up when it came back down that it went really high. But when we asked the clinometer readers they said it only went 121 feet high. Our team was still happy but we were also kinda sad that it didn’t go higher than expected.

 

In my class, almost everyone went higher than 100 feet. Except for one group, but it went 96 feet which is still high. My groups rocket went 3 feet higher than last time, which I’m actually pretty happy about. Not every group has wrote down how high their rocket has gone but so far the highest rocket went 136 feet high! Last time, the highest rocket went 192 feet high. I think when everyone changed something it totally made a difference in the rockets.

 

Our team was so happy after the launch and we were such a good team! During the launch we were all happy we could almost hug each other, but we didn’t. I think our teamwork paid off even though we argue sometimes. When we aren’t arguing we are getting along and laughing together. Because all of us but Charles were working on the presentation, he graphed it. He did a good job and that was our final graph.

 

After we had launched we all sat down by a tree to take notes of what we observed.
