YOU CAN'T *COAST* THROUGH THIS PHYSICS EXPERIEMENT!

The Bridge building has turned into a real-life amusement park with some new temporary decor: flexible gray foam tubes cut in half lengthwise, molded into wavy shapes, and taped up all over the science lab walls and hallways. There are tape markings and measurements to indicate distances, heights, and calculated slopes of the tube's curves. Physics teacher Simon Wright explains this 3D wallpaper: "They're roller coasters!"
 
During class, physics students hold a marble in one hand and a timer in the other, letting the marble go and timing its journey through the ups and downs of the tube. Then they record the time and repeat the experiment. "We're measuring the potential and kinetic energy of the marble," tenth-grader Alice Hockstader explains. Science experiments are always fun, but you could say this one is a real roller coaster ride!
