For the Bismuth lab I worked with Natalie, Kazuha and Annika. We started with doing the research as normal and discovered the melting point of bismuth and also how the oxygen effects the different colors of the Bismuth when you are crystallizing it. Here is a link to our research. During this lab I noticed that the bottom of the Bismuth when it was in solid form was not crystallized like the top and I was curious to why. After talking to Andrew and doing some research I figured out that the answer to this question was the amount of oxygen that that is being exposed. To create the crystals we first had to melt the Bismuth. We did this by using a hot plate. After the Bismuth was completely melted we scrapped the extra stuff off the top and set aside to let cool. Because we wanted blue crystals it needed little oxygen so we tapped the table a few times very genitally and this helped the crystals form. For this lab we got the results we wanted the crystals looked really cool, but I did not contribute as much as I would have liked. I think that. Even know we did two sets of Bismuth with a group of four I and the work wasn't that hard I would have liked to been a bigger part of this experiment. I also think would be a really good idea to do some more research on the background of Bismuth. Looking forward I don't think that I will be exploring Bismuth that much more maybe I could make a piece of jewelry with some of the crystals we made or I think trying to get pink crystals using helium would be a really cool experiment, but other then that I would like to move on.

First Stage:For this project Annika, Kazuha and I worked together. We started out by picking which rocket we would like to build out. There was one of two options, either the Cross Fire rocket or the Pay Loader. We went with the one that we thought looked the coolest, the Pay loader. After deciding which rocket we would like to build we began to do research on all the parts like the parachute and body tube. Here is a link to our research. We organized what we would like our time to look like as we go through this project in order to not get distracted. Second Stage:After we did all the research and got it approved by Andrew we began the building process. We started out by reading the instructions. Then began to piece together all of the parts. It was interesting to me to see how everything fit together, because this gave me a better understanding on how it all worked together in order to launch. A good example of this is the parachute, I saw how it fit inside of the body tube the motor would burn up and hit the ejection charge. When the ejection charges goes off it causes the parachute to eject and this provides the rocket with a safer more stable landing. While we were piecing everything together I was in charge of placing the fins were they belonged. Annika and kazuha took the measurements I cut and clued in order to make sure they stayed in place. This was the longest part of our process, because it took the fins a long time to dry and then we noticed they were crooked, this would cause the rocket to not fly as well, so we took them off and replaced them. After everything was put together we decorated it and waited for launch day. SS BaeBray its name:) Final LaunchFor the final launch we launched it at Fiesta Island. THis was a really cool experience, because I had never seen a rocket be launched. Annika and I went first. We shot off our rocket and it went out of view, so far infact it ended up about 10 feet away from the water which was on the opposite side of where we were. When we found our rocket everything had gone off correctly. The parachute went off correctly which caused the top to come off which is normal. The motor was still intact and nothing had been broken. The only damages was to the body tube which had a few dents, but nothing that made it unable to fly again. Something that I was very curious about after launching my rocket was how far did it go? I am really curious to how height and far the rocket actually went. If i were to do this experiment again I would really to like to document these things. I would also like to build a rocket from scratch, so I can figure out for myself exactly how everything works together in order to for it to fly correctly. I really enjoyed working with Annika and I feel like we make really good partners. I think overall we performed really well in order to make this project work. Taking out of this project I would really like to start taking notes as I go through my experiments, because I don't always blog right away and its hard to remember everything that happened and how I felt. I really enjoyed doing this, a lot more then I suspected and think that more rocketry will be fun to do.
First Stage: For the first steps of our project my group and I did research on lava lamps using the website http://oozinggoo.com/ This helped us to get more background on what we were doing and what the inportant information was. Mostly just about what type of body we would like to use. We also learned that the salt makes the water denser which causes the lava to rise. We then decided what we wanted our lava lamp to look like and Annika drew the first draft. We got in critiqued. The critique we got mostly explained how the light bulb would be touching the bottle and that shouldn't happen. They also suggested super gluing the bottle to the base. We got complemented on our base that we used and how it was the perfect size. Going forward and making our second draft we decided to space the light bulb and the bottle out more so they did not come in contact although we did not end up super gluing the bottom, because we used tape in order to be able to take it off when we would like. This is what our drafted looked like. I found this part pretty boring, but I knew it was a necessary part of the project. |
