Science - Viscosity


Sycamore class carried out an experiment which investigated the viscosity of plasticine through different liquids. We used water, bubble bath, vegetable oil and syrup and dropped each ball of plasticine at the same height and timed how long they took to fall.  The liquid provides a resistive force called Drag. Drag is a type of frictional force that opposes motion. The thicker, more viscous the liquid, the larger the drag force and the slower it falls. The plasticine fell the slowest in the syrup.
