Here is my homework, an essay on The Contraption
I thought the Contraption was incredible, I was amazed at how much work and creativness was obviously put into it. The amount of time and effort put into building The Contraption clearly showed, and it was amazing to see that the Contraption was made with mostly normal little household objects. I beleive the biggest motivation for the creators of The Contraption was how regular, little small things can really mkae up, and effect our lives , I also beleive that fun, and a knowledge of science were motivational factors.
There are seven linked matter and energy reactions in the edited Contraption video. First, the alarm rang when the second hand hit the 12 causing the rod to shake and fall, which hit the standing book down, causing the batteries in the paper to roll down into a small paper box connected to an object with a string. The weight of the batteries caused the object to go up and hit the manakin, like a pulley. The manakin swung, hitting CD dominoes, they all knocked down, and the last one hit a book, which fell over hitting something, and that something swung down and hit a ball. the ball rolled down a set track. At the end of the track the ball hit another ball, which fell off the top of the fire place hitting a blue ball, which swung and hit a yellow ball. The yellow ball hit an orange ball, sending it down a tiny set track connected to a little rod at the end. Lastly the rod hit an eject button on a little TV.
I have never seen a type of chain reaction that occured from The Contraption. However I have created something of this type, by setting up a few books like dominoes, then pusing one over. I have also seen a few videos where a long course of dominoes were set up, then one was knocked over, and the rest went in suit as they were hit. I beleive that most things like The Contraption are worth it, but they are a bit time consuming, and although they are fun, you could be doing better things with your time.
