Barbie Bungee Jumping Task

Introduction
In the last few weeks of school we are working on a task called Barbie Bungee Jumping. In this task we are seeing how much rubber bands are needed from a certain amount of height, and coming up with a conclusion. Then in one of the last few classes she will tell us to throw the barbie off a certain height, and we need to adapt to it. My group consists of three other people: Will, Lauren, and Ian. I believe we all have strengths that when combined will be really good.

What we did
We started out by finding the height of the desk and seeing if one or two rubber bands would work. Only one rubber band worked, so then we tried to make it higher. Then, we found out the height of a math book and see if there are any changes to the results, there wasn't. Then we added two books, three books, etc. Each book was a small amount which will be a good thing once we come up with our equation. We ended up finding a difference between when the rubber bands would touch and tried to come up with a solution, though I don't believe we have.

Consistencies
We tried each of the stages multiple times to ensure we have an accurate results. To be consistent we have decided to keep the barbie doll's hand down. This is because we don't want to take any chances with it touching the ground. Furthermore, when making a table we did not count the rubber band tied around the doll's feet because we didn't believe it contributed a great amount, plus we need to be repetitive.

What we found
We have found out that even an inch of extra inch will make a difference. Between book 7 and 6 there are a few inches different, yet the three rubber bands work on book 7, while it doesn't work on Book 6. Book 6 was the point where the switch off between two rubber bands, to three. Our next step is to see when one rubber band doesn't work. We also found out that working together is much better, since I believe that in the beginning of the class we weren't communicating. Furthermore when we came up with what we were going to do we got a lot of work done.

What we will do 
Though we worked slowly, I believe we did achieve a lot, and we did find out a lot of things in our research. I believe that for the next class we should begin testing out our theories with larger heights rather than a few feet. We have not found a pattern yet, so we must try to look at our data and analyze it. Also, we should construct a graph with all of our findings and see if there are any patterns. Additionally, I do believe we should also try to come up with a formula because it would help us immensely.

This video is one of our trials in slow motion. As you can see the barbie hit the floor, which means that the amount of rubber bands was more than needed. 

These two pictures represent how we organized our data as well as what we did last class.
