Bam! My mousetrap racer hit the wall! That is the last thing I wanted to happen. That is why I was very careful about the design of my mousetrap racer. I designer my racer so that it wouldn’t hit the wall. My mousetrap had some very strong points yet some faults, an if I could change anything I would have taken more time on the design. Also, if I had to grade myself on my work I would give myself a high grade. My racer functioned almost perfectly.
I designed my mousetrap racer so that it would turn at a 90 degree angle. I made the front end wheels straight, and my back wheels turned a little; which was actually a change from my original design plans because I was going to keep my back wheels straight and my front wheels turned. I also didn’t put the side wheels on the car because I tested it without them and found that they were just unnecessary. I kept everything else the same though. I extended my lever arm and tied fishing line on it. This way, when I wrapped the fishing line around the back axle and set off the mouse trap, it spun the wheels and the mousetrap racer went rolling.
I believe that the design of my car was very good, yet it did have its faults. The best thing is that it does make the turn. It also makes it to the finish line. That was my main goal. Though my mousetrap racer does have so problems. The racer is too slow. I wish I would have created it to go at a little faster rate. Also, my mousetrap cannot make it over the speed bumps. This is partly because it is too long and also because it is too slow. If I could remake my whole mousetrap I would definitely take more time on it. Plus, I would consider not only the turn that the racer needed to make, but also the speed bumps.
If I had too give myself a grade, I would probably give myself ay 25 out of 25. I would give myself this grade because my car design had everything required and my car also made the required 90 degree turn. My car had everything it needed to accelerate. My racer also made it from the starting area, around the 90 degree turn, and all the way to the finishing area, and stayed there. My mousetrap racer did everything that was required of it.
Building this mousetrap racer was a great experience. I never thought I could build it, but it actually wasn’t that hard. I learned how to build and design in a fun and challenging way.
