Roller Coaster reflection

In the 8th grade class at Carolina Day School, we were instructed to build a roller coaster using the lining on pipes.  One failure my group had was that the drop was too steep and so it would keep falling off the track.  After fixing that by putting a tunnel in, we had much success.  One of the skills of success was collaboration.  It was related to a motion unit because we had volocity. We talked about We would then drop the marble down the roller coaster and see if it had worked on the track.  Assigned to two partners, I thought It went extremely well.  My roller coaster met all the requirements assigned and we got a grade of an A-A+.  Our roller coaster, dropped, swerved, looped, and even went over some bumps. Although I was happy with my grade, it took until the last ten minutes of testing for it to finally work.  Overall our roller coaster was entertaining, exciting, and I liked working with my partners.  I am excited to see what next project we will be working on in class.
