John Evans on 14 Jul 17"Summer fun. It is the absolute best. Whether you visit Six Flags, Kings Island, a Disney Park, Busch Gardens, or another amusement park, the looping lines of roller coasters offer the perfect lens for getting students to interact with STEM concepts. An old garden hose, duct tape, and a marble: the only materials that you need to build a roller coaster. Cut the hose in half, and then duct tape the two segments together down the back to create a nice groove where the two hoses meet for the marble to ride, on top. Then the materials are ready for students to explore the potential and kinetic energy of roller coasters."
