Our Objective
Our Objective
Our task was to work with a partner to create a stomp rocket and launcher. For the first design everyone's rocket was the same but after that we were tasked with using the design process to improve or first rocket and the launcher. When improving the rocket, we had to identify three major problems that had to be fixed about the rocket. Then we had to make sketches of both the original and redesigned rocket. Finally, we shot the rockets and wrote down how we utilized the design process and the results of or newly made rocket vs. the results of the original design.
The original design
The original design
For the original design of the rocket, everyone's design was the same. The design consisted of 3, 2.5-inch fins, a 9-inch body, and a 1-inch tip. The materials that were used to make the rocket were paper and scotch tape. The trial that the rockets went the farthest in was the first trail when we shot the rocket at 35 degrees. The rocket flew 73'2" and 53'9". The second farthest angle was 45 degrees, where the rocket flew 49' and 48'6". Though the rocket should have flown the farthest when we shot it at 45 degrees, it was behind 35 degrees by 14 feet.

Some problems with the original design
Some problems with the original design
One of the problems with the rocket was the fact that when we launched the rocket for the fourth text the entire tip of the rocket blew off. As a result, we were forced to tape over the top of the rocket and continue with that for the rest of the time. There was also a problem with the fins. Because of when we shot the rockets, the ground was still wet. This caused the fins of the rocket to get wet and fold over top each other and start ripping. Finally, another thing me and my partner were trying to do was just make the rocket go father in general.
How we used the design process
How we used the design process
The first step of the design process is identifying the problem. Our problems were that the fins and tip of the rocket needed to be stronger and that the rocket needed to fly farther all together. The second step is to research. I while researching, I found that making the fins a different shape can create less resistance on the rocket and make it fly farther. After we decided what we were going to add to the rocket, we built the final design. Once the design was tested, we took the recorded information and analyzed if the design we made worked better, worst, or about the same as the original design.
Redesigned rocket
Redesigned rocket
In my groups redesigned rocket, we decided to go with the fully taped fins and tip on the rocket. The rocket also had the fins doubled for extra support so that they wouldn't bend over as much. Finally, we made the fins an elliptical, or ovular shape to reduce the amount of resistance the rocket was getting while in the air. The farthest that our design went with the redesign was 79' against the wind, but when shot with the wind, the rocket reached a distance if 164' 4". Then when measuring the height of the rocket when shot with a PSI of 40 and measuring it 50' away from it, the rocket angle was 60 degrees, and it reached a height of 86.6'.

How it relates to math
How it relates to math
It relates to math because when we were launching the rockets we had to use math equations and terms to figure out the highest point the rocket reached by using the angle at which it reached and how far we were standing from the launching area. The math we used was Sine, Cosine, and Tangent. In this case though, you would use tangent.
Reflection
Reflection
The changes that were made to our rocket were a success and they did what they were supposed to do. Going into this project, I didn't really know what to do but working with the design process and designing a new rocket and being able to test out what you made to see if it was successful or not, turned out to be pretty fun. Overall, I really enjoyed this project.
