I think the most exciting part of building our mousetrap car was when Andrea and I stayed after school one day, and completely rebuilt the model...it went from an unstable cardboard car to a successful sturdy car! We were both very excited and happy because we had put a lot of hard work into building the new model as well as formulating the idea together. There is no photographic evidence of this but I assure you it was very exciting.
In terms of teamwork, I felt our team collaborated together very well. We listened to each others' ideas, while staying on track, and were able to get work done productively. Personally, I feel I helped the group stay positive and on track (I was dubbed captain at some point, but it's no big deal). When our group was really depressed after our car broke for the second time, everyone was sad, including myself, but I turned our frowns upside down and said there was nothing hard work couldn't fix. However, I feel as though I could have helped a little more in terms of learning how to set the mouse trap. That confused me, so usually I was the video recorder, but I think it would've been helpful if I could have set the mousetrap to test it every now and then.
Overall, I think this project really helped me become a great team member as well as learning to listen to other peoples' ideas and opinions as well as contributing my own.

After two weeks of hard work and collaboration, the most exciting moment, to me, about creating our car was seeing it move in a straight line for the first time. I would post a picture or video, but it seems that every time I was in one, I was cropped out. I guess I just did not live up to the beauty of the car, but it was very exciting!! I promise.

Well personally I learned that just because I found an idea for a car, does not mean that it was the right idea. I just assumed that the small car with the cardbord wheels that I learned how to make on wikepedia was the right way to go. I told my team members what to do and in the end our first model fell apart. For our second try we were more strategic in our design, which was much more sturdy and I can't say it was my idea. I learned that I am not always right and even when I think I'm right, the best solution will come when you collaborate with our groups. Two heads are better than one!

Law of Conservation of Energy

The energy of our car starts with the sun. In order for trees to grow they go through the process of photosynthesis which is fueled by the sun. When the trees grow and produce apples from the photosynthesis, the apples are now a product of the sun. Us humans eat apples to get energy to go to the gym. We use our muscles from the gym to build a mousetrap car. So our car is a product from the energy of the sun. We then use our energy pull back the snapper the thermal energy is converted to potential energy which obviously started with the sun. When we release the lever the potential energy turns into kinetic energy which turns the back axle, which turns the back wheels. The back wheels use their energy to move the front wheels. When the car comes to a stop, because of friction, there is no more kinetic or potential energy, but their is thermal energy. The Law of Conservation of Energy says that energy could not be created nor destroyed, so our energy that we got from our food, which was created by the sun, created a car that always has energy.

Calculations

As we finished our car, we were able to calculate the overall energy of our car as well as the effeciency.

Maximum Velocity

After much hard work and dedication, our mousetrap car was able to score 2.98 as its final velocity! We are happy

Moving Car

Well the car is almost moving straight! I was having an issue with the setter because it would either fall off or get stuck so I decided just to hold down the snapper with my fingers instead!
