The Jazzin' Wagon

<---- Press that link to watch the powerpoint.
Overview:
We were asked to creatively create a car design (and prototype) that uses is fuel efficient and
uses no gas. It also had to travel a distance of 5 meters while carrying 250 grams. In our class, all
of the designs were either rubber band or balloon powered, and we
wanted our design to be
something unique; something that no one has ever thought of before.
So after some brief
brain- storming, we came up with the idea to make our car pulley powered.
Terms:
Energy:
Capacity for doing work.
Gravitational Potential Energy:
Energy due to gravity being at its height
Kinetic Energy:
Energy due to movement
Friction:
Force that affects motion
Pressure:
amount of force on a certain area
Entropy:
The degree of craziness in a system
Reflection:
My group and I pretty much new what type of car we were going to make on the first day. But we
had no idea exactly what it would look like. We started in class with a platform and small lego
wheels and a pvc pipe in the middle with a pulley on top. the string wrapped around the back
axle, through the pulley system, and attached to a weight at the other end. We were happy to
find out that the weight we used for the pulley counted towards the 250 grams that the car had
to carry, so we did not have to add any additional weight. After much trial and error, we realized
that our car hardly moved at all, and the due date was coming up. So we scheduled a night to all
work on it at Conrad's houses. At his house, we worked hard on the car in his garage and
listened to music until about 9:00 at night. The reason that this took so long is because we
decided to completely redo our car. We still used the pulley idea, but we made a car that was
more stable and worked better. We made the platform bigger, as well as using C.D,'s as wheels
because they were bigger than lego wheels. We had to keep making the pulley tower higher and
higher, so that the car would travel the distance it needed to go. Our car ended up being taller
than the tallest person in the class, which was a satisfying accomplish. Another great
accomplishment was coming in first place in the race against the other cars. I learned a lot
through this project, and helped create the next BIG (no pun intended) thing, the Jazzin' Wagon.
By the way:
I could not figure out how to put the video of our car here on my website, so be sure to check out
Conrad, Ruby, or Sterling's website through the STEM website. I believe that they posted them
their website.
