THE PROCESS THE PURPOSE - TO DESIGN A ROLLERCOASTER THAT WILL GO FOR 15 SECONDS THE MEANS – We bought our parts at Wal-Mart: plastic tub, funnel, tubes, tape, popsicle sticks, etc. We spent about $36…(the cashier thought we were making beer bongs…but the marbles perplexed her)

THE ROLLER COASTER A marble is dropped onto a piece of track attached to the top of a plastic tub…it then continues to follow a path carved by a plethora of track When the marble reaches the bottom of the track, it enters a tube attached to a ramp, and free-falls into a funnel which directs it into a labyrinth of tubing At the end of the tubing, it comes to a stop

WHAT HAPPENS At the top of the tube, the marble has potential energy… Energy lost due to collisions As the marble travels downward, its potential energy converts into kinetic energy

CONCLUSIONS PONTIFICATED The project took about 8 hours of physical work…more time went into coming up with a plan, going to Wal-Mart, doing the outline, the power-point, etc. PROBLEMS ENCOUNTERED: CO2 cartridges do not puncture easily…(dropping them on the floor does not work contrary to the belief of some) Spray-painting in cold, windy weather is not very efficient
