The rocket project
PRETTY LEGIT RIGHT? XD

Reflection
I thought the rocket exhibition for me and Sean was fun watching our rocket go up and the parachutes deploy. If I could go back and change my rocket I would, I would change our rocket design and use smart water bottles and a bigger pressure chamber. I would like to change it because I would like to have better results and see my rocket go way higher. Also I would recommend this project to different schools because it was a really fun project and I got a lot of learning out of it. I thought this was one of the best projects throughout my school years because we got to build and learn a lot about rockets.
My emotions to this project were good and near the exhibition was kind of sad. My emotions were happy in the first part because our rocket was going good and everything worked on it, it was a pretty good rocket. Also I really liked this project a lot and I was sure we were going to get a good grade. I was kind of worried towards the end of the project because things weren’t really going good for me and my partner Sean. During our third test rocket launch our rocket blew up because the pins wouldn’t come out and the girl ran away. We tried to build a new rocket for the exhibition but it had a lot of errors and we just brought an empty 2liter bottle for our exhibition, that wasn’t good for me and Sean. But we got another couple of days to build a new rocket and just do a mini exhibition, we fired and the rocket was pretty good but we could have done better but it gave us a passing grade. These were my emotions during the rocket project that kind of went up and down a lot.
Conclusion
At the
exhibition me and Sean’s rocket took off at 38% degrees angle and had a maximum
height of 24.1m, the observers were 30 meters away from our rocket. To
calculate the maximum height we multiplied the distance from the observation to
the launch pad in meters by the tangent function of our rocket’s flight angle. To find the average flight velocity, I
multiplied the rocket’s maximum height by two then divided it by the flight time
6.61 seconds. This gave us the average velocity of 7.30m\s. The theoretical flight
time of our rocket was 4.4 seconds. We calculated this by dividing the maximum
height by 9.8(m\s) by 0.5. Then you find the square root of the number and
multiply it by two this gives you the theoretical flight time. After doing the
calculations we figured out that there was a 50.22% error for our rocket. Our
rocket’s flight was good because it almost went straight up and had two working
parachutes that deployed and worked.
