This is a project I do with my 7th grade students that involves 110# cardstock paper, tape, and marbles. The goal is for the marble to travel for 30 seconds. Bonus points are awarded for loops, corkscrews, hills, jumps, and openness of track. The elevator is a real pain in the butt, but it's awesome when it works!
