Stokes' Law Exercise for "Rocks and Minerals"

Karen Bartels - Northeastern Illinois University - Chicago, IL

Summary

In this laboratory activity, students are led through a qualitative/semi-quantitative derivation of Stokes' Law. Lab groups brainstorm on and hypothesize what factors will affect the settling velocity then time the settling of various objects of known composition and size through different fluids of known viscosity to validate or invalidate their hypothesis. Additional activities that can go along with this exercise are outlined in the Teaching Notes.

Learning Goals

Context for Use

This exercise was developed for second-year "Rocks and Minerals" course for Earth Science majors and minors. Physical Geology was the only prerequisite. The class was usually around 20 students and the activity was conducted in groups of 4.
