What keeps you in your seat when you are on a looping roller coaster? In the "Centripetal Force" #physics #science project, students use plastic cups, marbles, and differnet colors of JELL-O® to explore the movement of an object during circular motion. Which way will the marble go? [Source: Science Buddies, http://www.sciencebuddies.org/science-fair-projects/project_ideas/Phys_p018.shtml?from=Pinterest] #STEM #scienceproject
