This was my first time ever being a part of the Mousetrap Race car Challenge, and I must say, it was quite an enjoyment. IT was the first 'project' we actually did over a period of one+ weeks and it involved a lot of design, intuition, and time.
Our team design was just a simple car (4 wheels on axles) being thrust forward by a string attached to the axle and a mousetrap (placed on the car; portraying the body of the car).
Here are some pictures of our Car in creation phase and final product phase:

One of the points of this project was to accomplish the most achievements; We earned Eight (8) total

"Build It" - Build your design. Document it with a photo.
"The Price of Glory" - If each part you use costs $1, generate a total cost for your build  :: Our design used a total of $23
"Competitor" - Compete in the 2nd Annual Mousetrap Race car Challenge.




"Feedback" - Collect feedback from yourself or your classmates.
+ It was a good design, accelerated quick and went quite far
change : the way in which you accelerated the car wasn't the best way (not enough pull on the string)
? Why would you use the mouse trap to pull the string, not as strong as yourself pulling the string.
! Looked sleek and clean, well created

"Game Changer" - Develop a new rule or change to the game that you feel would make the event better. Explain your concept.
I think a new rule would be that everyone needs to move out of the way, and that we must actually make a track to do the race on, because some cars (like ours) got blocked by people's feet who weren't paying any attention - Small space to go in the middle of too.

"Re-work" - Change your build based on your experience with the race/feedback you collected.
 We made changes to our mousetrap racecar by replacing the axel with a better piece of metal, and changing the way the string (powered by the mousetrap) pulled/flung the the racecar.
"Name it" - Invent a name for an achievement that you think is better than what we have currently.
I think a cool name would be "The Big Cheese" for the winner of the long distance challenge.

"Leave It Cleaner Than You Found It" - Did you leave your workspace cleaner than you found it? Explain.
Oh, EZ and I certainly cleaned up our pieces everyday, including the day of the first race without a doubt. We also helped clean up whatever we found on the floors (not only around us)

All in all, this was a fun project, and the classes which do it next year will most likely have a great time, even with minimal changes to the way we did it this year.
