Viscosity of Oil Tube Set
Description
The Viscosity of Oil Tube Set consists of five transparent plastic tubes containing oils of different viscosities. Each tube also contains a white plastic ball and a metal ball. The balls fall through the tube at a constant speed that depends on the oil viscosity, the angle at which the tube is inclined and, to some extent, the temperature. Colored caps identify the type of oil in each tube. Two O-rings may be slid to predetermined locations on the tubes to assist in timing the motion of the ball.
Students gain practice setting up experiments, collecting and graphing data. When given the viscosities of three of the tubes, students can use the processes of interpolation and extrapolation to discover the viscosities of the other two tubes. They may also be challenged to predict the effect of temperature or angle on the travel time of the balls and to design and conduct experiments to test their hypotheses.
