One problem we occurred was that we could not just cut out balsa wood and attach them to the side they will get ripped off with the for motors putting out 8000 grams of thrust so what i did for a whole day was i got the tube found the surface area of the whole tube then got the point of thrust on the tube and had to find it for each side once i got that i had to take that and there was a only small amount of surface area i could use for the each fin and i got 30 inchs of total surface area and i ended up with a total of 40 inchs. Above is a video the fins i designed and laser cut The next thing we did was we needed a way to attach the fins on with out just glue so i made little indent slots on the fins so if we made wholes we can make a stronger bond with glue but we tried to cut into the tube but that was eight layers so it would have taken for ever so we got the dremel and cut it out. The holds were loose and i needed something better to hold them together. So what i did was made little metal crossbeams inside the rocket and on opposite fins to increase strength and rigidity. This is the final rocket and is ready to fly and has been fully painted to look just like an x wing this project has been amazing and there is nothing i would change if i could make the rocket bigger i would that the only thing i will regret but still its a bad ass rocket still but i learned alot from this project and hope to do more with rockets. The video of the launch will be posted soon
How do you feel overall about this class? What characterizes your experience?
This class was amazing and it fianly felt like HIGH TECH HIGH again being able to do what you want explore into your passions and just doing projects no homework no exams it was honestly my favorite class i have taken here . I really wish we could have had a full year of chemistry so i could have gotten into more chemistry stuff like with test tubes but everything we did this semester was amazing . What did you learn about yourself as a learner? I learned that i can work with groups but knowing how i am and who i choose i need to be the leader in the group and i need to lead the group if i want to get things done When was a time or what was something you did when you were driven by curiosity? The fermentation project i did i really didn't know much about but my brother did something similar with root beer so i wanted to do ginger beer with carbonation my brother didn't carbonate his root beer but i did with my soda. When was a time or what was something that you did when you weren’t driven by curiosity? The rocket project because i have worked with rockets before but that doesn't mean that i didn't love it i loved how we went through phases of it to clearly understand what was happening Please share any remaining thoughts or feedback. Andrew I want to thank you for everything you have done for me this year and what your class has done the fact that you treat us like adults is great because then i do not feel like i have to do anything but if we dont then we fail so you are giving us that responsibility and teaching us to be mature. You are such an amazing teacher i always waited until after lunch to come to your class and start working. When i was having a horrible day and we sat down and you started telling us story's and making us laugh always helped and working on projects and assignments in your class always got my mind off what was going wrong. I am going to miss being in your class and miss working with you i hope later in time you can be my teacher again For our rocket design we decided we did not want anything to fancy and crazy yet for this rocket we just wanted to see how our motor preforms and to make a good rocket that just goes straight up and doesn't blow up or go out of control. So we drew a basic design and made sure that the fins were symmetrical and proportional to the rocket . What Asheigh drew below is some what our rocket looks like With this rocket we did not wait to start building it we started the first day we could ashiligh made our motor tube and we started cutting out the fins in the same day once we got that and the nose cone all attached we needed paint so we went on an adventure with Andrew to ace and to get paint so we could turn our ugly brown tube into a spiraled american flag once we were there we needed stars if it was going to be a flag so we bought stars and got back and immediately started painting and once the paint dried we got super glue got 50 stars divided them by 4 and put one on each fin. For our launch i was very happy with how it flew the motor started off slow then the trust kicked in .The rocket went straight into the air and went about 400 to 500 ft and once it hit apogee we had a little problem the ejection charge did not go off so the rocket came straight down and crashed into the floor but i ran over there to check on in and there was no problem with it, it was perfectly fine WE MADE GINGER BEER and it was a very fun experience because each one we made we did something a little different and made them taste differently. Our experiment did work and it was really good and one of them was really bad . So what we did was got ginger root, bread yeast,molasses,sugar,water,and jars. We filled the jars with water and we didn't have the tools to boil the water and the ginger so we improvised and filled the jars with water after we did that we put it in the microwave for 2 minuets and once that settled we poured in a lot of sugar then again we put it in the microwave. Once that was done we shredded the ginger and cut it up and divided it into the jars then swirled them around then again we put it in the microwave. Once we had that all done we were ready to put in the yeast but Alex opened the cupboard and found molasses that was one of the ingredients we needed but didn't have so we put a spoonful of molasses in each jar and in 2 of them we took the ginger out and two we let sit and stay in there. WE WERE FINALLY READY for the yeast but then we were told if we put to much yeast the jars might explode with pressure so then we had to measure half of a tablespoon then divide that by 4 and take one of those and put it into the jar once that was done we waited and let it ferment for 4 days. So for the past semester I have been working on shaping rocks and making necklaces and I am not really sure why I enjoyed shaping the rocks but it was interesting. So first I started of with getting a giant chunk of rose quartz and got a hammer and hammered it until it shattered in to pieces . I took that and started getting to work first of I put the rock on the blade and flatten both sides and once I got it to the way I like I started smoothing the sided and I wanted to make a heart for a certain reason and once I got it to an oval shape I needed to get the indent that the hearts have I took of the guard for the labadary machine and used the corners to cut into the rock and started rounding around and once I was finished I really wasn't but at the time I thought it was fine but there were 4 more stages of polishing . What I learned from this project was to be patient and that you can make something so plain and boring into something nice So for this lab braydon walked in and became our teacher for the day. The first thing he asked us was do we know how make snow well its kinda like snow and I was kinda aware already what we were going to do but didn't really get why it would be like snow so i was confused? Looking BackSo for this lab we were all given a red cup with little balls at the bottom of it and we were also given a flask full of water and told to put the water in the cup and see what happens so as we were doing that the water was going away and the balls were expanding and absorbing the water and soon after we all realized we were using the stuff that is used in baby diapers . Which is called Sodium polleycrylate and it is a sodium salt that is able to hold 200 to 300 times its weight. Looking beyond
Looking inwardWe did get what we desired we wanted to find out what happens when water is applied to sodium polyacrylate and we were also instructed on what to do so there was really no way of not getting the results of what we wanted and in this activity i think i acted a lot more different because last time i wasn't really interactive and didn't want to touch it but now i was more into it and messing with it and seeing what was happening. Looking outwardOn this lab I worked with Chiara ,rose, Zach,and emily and as usual we were messing around and talked a lot but we always do get our work done so I think we worked fine because we all know how eachother work and we know when to get ourselves on track. On this lab i was participating more than i have in other labs and was not really taking a charge but I was getting into the work. Looking ForwardIf I were to do this lab again i would like if i worked with a new group to collaborate with other students besides the ones i have been working with all year. I really don't see a way to expand this lab but I did look into it deeper to see what was happening on the molecular level and the phase was called osmoisi
So this semester was very interesting and a lot more open we had already gone through section one so it was easy on knowing what to do just the matter of doing it. For this section i know that i get distracted really easily and there were points in time where i needed to something but i just pushed it to side but next section i know i need to stay on track more. So for the next time you do the rocket project i thought it was fine and everything is given to us and we just need to do it and i like that so i would keep doing that. With the google cardboard i didn't like it to much maybe more on the side i didn't get to do much but it was just kinda something i already done so maybe that's why but overall it was a good way to do something fun
Group : Andrew Ashleigh Miles This is the thrust curve we got from our motor
So for our rocket motor we were deciding between the two choices of black powder or sugar and the both had there perks but we didn't know what we wanted because with black powder the initial thrust is very high and it spikes up really high but only for a period of time and sugar motors may not get that much thrust does not mean its not bad with sugar the duration of the burntime is a lot longer than black powder and it also has less of a chance to blow up on us and why would we want to put so much time into a rocket then it blows up when we launch it .
