LI : To make a Rube Goldberg machine to complete a challenge

The challenge for our Rube Goldberg machine was to turn on a computer without using our hands (Rube Goldberg did not make the simple machines he used the simple machines). This challenge went on for a few weeks the video is our final results

We used 4/6 simple machines, we used the inclined planes to help travel a marble and car, then a wheel and axle (which is the car) we used it to hit someone so they can do an action. Next was the pulley that had a block attached with it, the block would the hit the power button which will then turn on the computer. The last simple machine we used was the lever (dominos) which will hit me to then make me to turn on the pulley.

We made the inclined planes out of a meter ruler, The wheel and axle or car was just a small hot wheel car. The pulley which was the hardest to create The pulley had weighing bars taped together facing horizontally, Then a string wrapped around to hold the block with a enough string left to make the pulley go up and down. And the dominos was already in the classroom so we did not need to make it 

The hardest part of the challenge was testing it over and over again until its right and also making the pulley, because one of our group mates did not make the pulley so we had to make one with class materials.
