Stretching out to the corners of the gymnasium, the indoor roller coaster at Royal Oak Intermediate School appears gargantuan compared to its creators.

Twenty-four feet tall at its highest point and occupying 10,000 square feet, the fully-functional ride towers over the 135 eighth-graders who are its designers, builders and decorators. Students and four teachers have spent thousands of hours measuring, sawing, constructing, painting and decorating the wooden structure over the last three weeks....

"The nervous part is waiting for it to work," said Jacob Jimenez, 14. "The kind-of not-nervous part is it's ours. No matter what happens, it's still ours. It has to work."

...

Of all the skills used in constructing the ride, such as physical science and math, 14-year-old McKenna Gooden said the most important is to "work with peers" and "connect with friends and get it done."

"It's pretty amazing how us kids - 14-, 15-year-olds - can build a 400-foot roller coaster," she said.
