The pulley is dropped from one side causing the other side with the red solo cup with the marble in it to drop and begin the course. The marble hits the elastic on the incline plane and bounces to a magnetic block going down the remainder of the incline plane. The marble then drops off the incline plane dropping into the ice cream scoop. This causes one of the sides of the ice cream scoop to be heavier causing the other side to go up releasing the Lego car down the second inclined plane. At the end of the second inclined plane the Lego car knocks over a row of dominoes. The last domino with a magnetic marble on top falls over the magnetic marble rolls and hits the bell causing a sound and then is attracted to the magnetic block.

 

 

Gravitational Energy: The energy in the marble when it is in the red solo cup being held above ground levels waiting to drop. The energy in the marble after it lands into the ice cream scoop.

Elastic Energy: The energy in the elastic band as it is being stretched by the red Lego rod.

Mechanical Energy: The energy in the marbles as they move through the course. (As they are rolling)

Magnetic Energy: The energy of push and pull between the magnetic marble and magnetic block.

Sound Energy: The energy transfer from the magnetic marble to the bell to cause the ring.

Science 10- Paper Airplane Experiment

During this first week of science, we performed our first experiment to see which paper plane would go the farthest. Me and my partner chose three different designs of paper planes to see which one of those designs would go the farthest. With this experiment I learned that sometimes our hypothesis can be correct. In our experiment my hypothesis was proven correct, my hypothesis was that the largest plane would go the farthest. I thought this because this plane would have less folded over components to it making it less heavy causing it not to descend as quickly as the maybe heavier ones. Even though we can’t know for sure if that is why the largest one went the farthest it is still very cool to see my hypothesis being correct. I also learned that it can be challenging constructing certain types of paper planes more than others. If I were to do this experiment again, I would like to try it by choosing a different factor to change to see which plane will go faster, for example possibly, testing different weights or even different types of papers. However, if I were to do this exact same experiment again, I would like to try with someone else throwing the planes to see how that impacts the results.
