Roller Coaster Project

In science, we are making roller coasters out of paper towel tubes, milk cartons, and other common items. The requirements of the roller coaster are:

-it has to have at least three hills

-it has to have at least one other roller coaster feature

-it must be completed in the time given

-you must buy all materials using "Omega Money" that you earn from teachers

Our group's roller coaster, which we have decided to name "Sachmokido" for the two first letters of everyone's name in our group, unfortunately does not meet requirements. Though Sachmokido does not meet requirements, my group and I had fun assembling it. While this assignment was a lot of fun, it also related to Newton's laws. For example, the marble does not move until it is dropped into the start of our roller coaster, as stated in Newton's First law of motion. Newton's Second law is demonstrated by the marble picking up more speed at some points, and slowing down slightly at others. Our roller coaster relates to Newton's Third law because when the marble hits the tape we put at the end to stop it, we then tilt the roller coaster the opposite way, making the marble go in the opposite direction it was going before it hit the tape. I think this was a very fun and very educational assignment, and my group and I enjoyed it a lot. If only all assignments were this much fun...
