Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.

Overview and Learning Objectives

Students can adjust temperature and toggle views of van der Waals and charges to discover the nature of hydrophobic and hydrophilic relations of molecules with water.

Students will be able to:

  • discover the difference between the way polar water relates to nonpolar molecules such as oil, and other polar molecules, such as ions.
