VSEPR Ball and Stick Molecular Models

VSEPR Balloons of the five basic shapes of molecules,

A parody of one scene in Star Wars Episode IV A New Hope. Obi-Wan Kanobi, Luke Skywalker, C3PO and R2D2 enter Mos Eisley on Tatoonie. They are stopped by Stormtroopers and questioned about the droids they are transporting. In the skit, Obi-Wan Kanobi and Luke Skywalker are tranporting ozone and calcum carbonate.

Students visualize and represent molecules in 3-Dimensions. High quality plastic individual model kits for VSEPR configurations are used to enable students to build molecular models. Using an active learning approacah, given a molecular formula, students draw the Lewis Structure, Identify the total regions of electron domains around the central atom, build the model of the molecule, draw a 3D representation of the molecule, identify the molecular shape, identify the bond angles, and classify the molecule as polar or non-polar.
