Rocket Project
The Picaso
Rocket Log:
1. Day 6, Entry 1: 9/25/13 Day after 1st test launch. Today we are going to work on our nose cone. We will also work on perfecting the parachute an talk about completing the challenge extension (lifting 1 KG.) 2. Day 7, Entry 2: 9/26/13 We are going to try to launch today and fix our nose cone. We decided to make our rocket bigger by adding a bottle. 3. Day 8, Entry 3: 9/27/13 Today we decided as a team to start over with three smart water bottles. We think this will work better to fly higher because of how tall the rocket is. Also, we are adding detail to make our rocket as perfect as it can be. 4. Day 9, Entry 4: 9/28/13 Our class is launching today, but unfortunately we do not have a completed rocket to launch. We will watch the rockets and sand our bottles in order to glue them together tomorrow. 5. Day 10, Entry 5: 9/29/13 We had a quick 30 minute work day today. So, we used boiling water to mold our rockets to fit together. 6. Day 11, Entry 6: 10/8/13 Today we painting are glued together rocket, and worked on making a more perfect parachute and nose cone for tomorrow's launch. 7. Day 12, Entry 7: 10/9/13 Today we fixed our nose cone and weighed our rocket. Our rocket in 1.70 Newtons and 19cm long. 8. Day 13, Entry 8: 10/10/13 Today we finished up our parachute, nose cone, and design details. We are officially ready for the launch tomorrow! 9. Day 14, Entry 9: 10/11/13 Exhibition day! We are launching at 70 psi. Let's not detonate our rocket today! |
Rocket Reflection
Dylan Williamson The exhibition for my group was an adventure of nerves and a callous subject, through the explosion of The Picaso. It wasn't necessarily mournful, watching your rocket suddenly explode launching the leading part of the rocket off into the azure blue sky, it was more of a comfort. I was done and I was illustrious of my hard work and dedication no matter what occurred. If I could go back and do it all over again I would make sure the glue was secure and ready to launch. I would also make sure that all of our group members are present so we could enjoy the launch to as a collection. I was really disappointed regarding the fact that not all of our group members were there because we went through all of that work together but not all of us got to see our finished project, explosion or no explosion its magnificent to be together through the end. Some advice that I would give other groups is make sure you test your rocket multiple times, to make sure that it is ideal and able to resist your pressure. The test and the launch are much contrasting and what your rocket could withstand at a satisfied pressure, the test may explode it at the launch. Also make sure that you work hard on your parachute so that it deploys effortlessly and creates a secure landing. The challenge extension is also a very significant part of this project, even though are group couldn't execute this, we still tried and it was a challenge. Overall this project has taught me a lot about PAPER: persistence, advocacy, perspective, evidence, refinement. This project especially made me really focus on the Habits of Heart and Mind. Overall this project was a fun academically challenged roller coaster, that showed you what you really know. |
Conclusion:
At the exhibition the launch pad was 174 feet from the observation table. If your rocket were to fly up like ours to your angle would be 15 degrees. The actually hang time was 4.67 seconds, this was recorded by the data team. Our hight was 46 feet, which converted to meters is 14.01. In order to convert feet to meters 3.2808, which is the amount of feet in one meter. The we calculate actually velocity, which is taking The max hight, accelerating upwards and downwards, divided by the actual time. We made the calculation and found our average velocity was 5.99 meters per second squared. Our next calculation was finding our theoretical time which was found by d=1/2at squared which means taking 5.99 (our average velocity) times 4.67 seconds (our actual time) divided by two. Which comes out as 3.499 (Our theoretical time). After we got our theoretical time and our actual time, we can calculate our percent error in flight time. For this calculation we took our actual flight time and subtracted by a theoretical time. Then we divided it again by our theoretical again. Lastly, we multiplied it by 100 and we got the percent 33% meaning the theoretical time was only off by 33%. Over all these calculations really helped me understand our rocket project better, and make my understanding off math increase in this area.
