SANDPOINT — Sparks flew, reactions simmered and fireballs erupted in the Sandpoint High School gym Friday during the annual Science Circuit hosted by the school’s upperclassmen.
During the event, 125 SHS students enrolled in honors-level physics, chemistry and anatomy and physiology courses showcased scientific phenomena including electric currents, Newton’s laws of motion and ferrofluids to fifth and sixth graders from schools across the district.
At one station, high schoolers demonstrated the conservation of angular momentum with a bicycle wheel and a low-friction turntable. Participants stood on the turntable and held the spinning wheel using two handles attached to its hub. When they rotated the wheel left or right, they found their whole body rotating on the turntable in order to compensate for the wheel’s change in angular momentum.
