Designing and Building Rocket #2

For designing and building rocket 2, we could only change one thing so our group decided to change the shape of our fins. We didn’t copy any of the other groups fins but we did take the groups fins that went highest and combined them together and made a great fin. We did the same body and nose cone but changed the way we added the tape. Instead of doing a yellow piece of paper and a red and yellow tape spiral, we did a black body with yellow ring of tape around it. I think it is going to go higher because there is less tape and smaller fins so there is less weight. I hope that it will go higher this time. Last time, our rocket did not go that high so this time, after experiences, maybe it will go higher!

Launching Rocket #1

Today is 10-4-19 and today is the day that class 5C launched there rockets.

There are 6 groups. The Astro-rockets, The 4 Rocketeers, The Three Musketeers, The Astros, and The Shooting Stars (my group). 

We all went outside to the field and Mrs. Cooper set up the launch pad. The first group was the Astros. They all put on their safety goggles and the air pumpers put the air in the rocket and then the countdown master counted down from ten and then the launcher pushed the button and the rocket went up. There were 4 clinometer readers because the sun could be in someone’s eyes and they would not get a good reading. There were also 2 people taking videos and recording the countdown and launch. This routine went for all of the groups.

The next day, we took the average height of the rocket, transferred it into feet and added the average height of a fifth grader. then, we wrote the data down on a piece of paper, we put our groups rocket with it and everyone walked around and looked at the other groups data.

Designing and building our first rocket had its pros and cons. First was the designing.

We made an inspiration board to help us see what we needed to do. We had to make a nose cone, a body, and fins. We had to decide what shape the fins were going to be, what size body, and what shape nose cone. One of the cons of doing this is that we all have to agree on the stuff to put on the rocket. This is a project all about working together and communicating. The steps to building the rocket are first, we have to take a PVC pipe and wrap a piece of paper around it to make the body then use electrical tape to wrap the body in the colors we want and to make sure it stays secure.

Then, we had to decide on the shape of the fins. Hana and I wanted one shape and Mark and Asher had another idea so we had to come up with a fin that combined all of our ideas into one fin shape.

Then came the nose cone. We all cut out a circle and cut one line to the middle and folded it. It turns into a shape that looks like a party hat. Then, we had to attach the nose cone to the top of the rocket and the fins around the bottom. We did four fins. Our group name is the shooting stars and the colors of our rocket is red and yellow.
