Student Activity - Racing marbles

Activity idea

In this activity, students compare the viscosity of common household substances by measuring how fast marbles move through the liquids.

By the end of this activity, students should be able to:

  • set up and carry out a test, keeping variables constant
  • use a graph to communicate their results
  • apply their understandings about viscosity to everyday situations.
