Day Three

I composed are written test results into microsoft excel today. I had alot of trouble figuring out how to upload it into a blog so I just created a copy and paste box and simply copied and pasted.

 CAR SPEC's
We built are car exactly by the book and we had few personal variations. The only change we made is that we took out the gears that made the car 4 wheel drive. The first day we we're building we forgot to put all the barrings on so it made are times 2 seconds slower so we had to fix that are second day.
 
The lighter the car ther quicker it seems to go. I figured that out while testing the different batteries. The nickel metal hydride was a whole ten grams heavier than the nickel cadium. The car with the nickel cadium batteries trunced the nickel metal hydride by a whole 3 seconds!

second day

Tried to test today but we had several mistakes when we were building. We didnt have the circuit for the batteries connected properly. We forgot to apply are barrings to are car's wheels as well. The few tests we did are speed was extemely low. We're fixing are car today and getting better tests done next class.

first day

I got partnered up with Devonte today. We started building are Tamiya Car but we came up just a little short of finishing. We didnt grease all of are gears like the instructions said so that might affect how are car runs but only time will tell. I personally dont think it will effect the car to greatly. we should be ready to test next class.
