  Lesson Plan: The Right Polymer for the Job Mark as Favorite (19 Favorites)

  In this lesson students are introduced to polymeric materials by exploring polymers (mostly plastics) used in automobiles. Students will learn about the features that all polymeric materials have in common and the features that distinguish one polymer from another on the molecular level. Students will learn how the molecular differences translate into property differences. The selection of a polymer with the right properties for any particular application is of critical importance in an automobile.

  Lesson Plan: The Great Race: A Study of van der Waals Forces Mark as Favorite (9 Favorites)

  In this lesson students will investigate intermolecular attractive forces, van der Waals forces. They will construct models of specified molecules and use the models to identify the van der Waals forces that exist between molecules of each substance (London dispersion forces, dipole-dipole forces and hydrogen bonds). Then, using manometers, teams will perform a series of races to determine which substance has the stronger van der Waals forces.
