Graded Bungy post Three

Today was our test day, Mr.Oksness gave us a random location to drop our barbie. Our teacher chose the stairs in the lower school as our drop.The height was 483cm. Our prediction was that we needed a total of 35 rubberbands. We came to that conclusion by using our equation that we made last class, y=13x+27. So, what we did was plug 483 in the equation as Y. It looked like this, 483=13x+27. Then we subtracted 27 from 483 in order to isolate the X, which would give us the amount of rubberbands we needed. After subtracting 27 from 483, we divided the result of that by 13 and X=35. That meant that we needed 35 rubberbands. When we dropped the Barbie, we only used two tries for the Barbie to get as close as possible to the ground. We literally almost touched the ground in both tries. Our teacher then chose another place for fun, and curiosity. It was aproximently 8 meter high.However, our prediction didn't quite work out that time since it touched the ground a little bit. I think the reason for that was because the rubberbands had expanded since we had used them to test our equation and for the big jump. I believe our group did a great job, we were productive in everyday even though we were a man shy. We did a really good job figuring out the equations, and making good predictions. One thing we need to do better is after we did one test with the rubberbands, we should change each one because the rubber bands were already expanded so they were larger. We did achieve our goal, and that was to keep Mr.Oksness daughters barbie safe, and making it go very close to the ground. I hope we can do similar projects in the future.
