Viscosity of Oil Tubes
By timing the fall of a sphere through different known grades of oil, the student can construct a time vs. viscosity graph. This graph is then used to determine the viscosity of an unknown oil. The set of five tubes of oil are sealed with both steel and Teflon spheres. The instruction manual relates values to SAE Grades of motor oil used in automobiles. This lab stores in a minimum amount of space and requires very little teacher preparation time from year to year. Great for practice in recording data, graphing, controlling the variables, etc.
