To successfully pass this challenge, students had to create a freestanding and stable roller coaster that was at least 6 feet long and contained at least 2 loops, 1 camel back, 1 whirlybird, and any additional maneuver of their choice. Additionally, the marble (aka "the passengers") had to travel through the entire roller coaster without falling out.
I am happy to announce that all students mastered this challenge and all "passengers" arrived at the finish point safely!
