FC: Rocket Mixbook | By. Varenya Shrikant
1: Our class was working on a project that determined how one would make the highest shooting rocket. We started off with some research. Our class "skyped" with a pilot and he gave us some good tips.
2: Pilot Tips: 1. 4 fins on a rocket 2. 4 forces of a rocket/airplane: weight(weighs aircraft down), drag (moves aircraft back), lift (puts aircraft in the sky), and thrust (moves aircraft forward). 3. No flat surfaces on top of rocket, for smooth airflow and no drag. 4. Round, point nose on top of rocket. 5. Long, narrow tube for rocket's body.
3: Experiments | After our research, we did some experiments. We tried to figure out the dissolving time of solutions. For example, we dropped a tablet into water, vinegar, and oil. We timed how long it took for a 1/4 tablet to dissolve. I also varied with different temperatures. In the process, our class learned that a tablet could dissolve faster in hot water than in cold or room temp water. We also learned that vinegar dissolves better than water!
4: Imagine | With our thorough research and experiment data, we were ready to start. First, we imagined what our rockets should look like. We brainstormed our solvent, solute, and temperature. These would later make the engine for our rocket. I took my research and tips from Captain Rosenstein (the pilot), and used it in my rocket. Later, we went to Google docs and made our first rocket blueprint. Please see my blueprint on the next page!
6: Why | My group chose hot solvent, because tablets dissolve faster in hot solvent. We also wanted our solvent to be vinegar, since tablets dissolve quicker in vinegar, than in water. Of course our tablet size was a full tablet. Since we wanted the tablet to last longer, a full tablet was necessary.
7: Plan | I got into my rocket group and we discussed our blueprints. After everyone had presented their blueprints, my group, Hunter, Cole and Troy, took a little bit of everyone's ideas and used it in our first rocket. Our first rocket was to have 4 rhombus wings. We had a pointed nose on top, and a long tube made out of construction paper for the body. Our group was to put a little canister and stick into the body. We would later fill it with hot vinegar and drop the tablet in, causing the rocket to blast up.
8: Design | Like I had said before, we made a long, thin tube of construction paper for our rocket body. We had four rhombus wings. Our rocket also had a round, pointed nose, just like the pilot had suggested. Hunter stuck in a little, plastic canister. We later poured in some vinegar and dropped the tablet in. On the next page, I have posted our first rocket data. This chart contains info of our rocket and the other groups' rockets.
10: Improve | After we finished our first rocket, we got together as a group and discussed our rocket's performance, along with the other rockets' performances. Each one of us suggested a way to improve. This time, we came up with a MUCH smaller rocket. We thought this would increase our chance of shooting the rocket high. The four fins were still rhombus, but the size decreased. I also put less tape on, to make it less heavier. We were confident about our rocket.
11: On the next page, I have posted our 2nd rocket's picture.....
13: 2nd Data Chart
14: Share | Based on our data charts, group 2 and 3's rockets performed the best. We learned that maybe vinegar is not always the best solvent. Sometimes, it is too extreme and makes it blast off too soon. Hot water is the best choice. Also, a half tablet is enough to make a rocket blast off. A full tablet would just be wasting tablets. One group became even MORE creative and broke a full tablet into halves, then dropped both of them in. Another thing we observed, was that most of the improved rockets were much smaller. The wings were tinier, too. This probably made the rocket shoot up higher.
15: What We Can Do Differently Next Time | I think next time, we should pay more attention to the other groups, especially the highest shooting rocket group. This way, we can steal their ideas and make our rocket successful!
