This activity includes a set of directions to assist students in designing an inquiry to explore intermolecular forces. Since this is inquiry, the directions are somewhat limited. One of the solutions used has only dipole-dipole and dispersion forces, another has all three Van Der Waals forces, and a third has ion-dipole forces in addition to the Van Der Waals forces. In addition to the student directions for the inquiry design, I offer a page of ideas to help the instructor guide the students to design tests to reach valid conclusions regarding molecular behavior as it relates to intermolecular forces. Also included is another brief activity exploring similar concepts.
