The POGIL method of learning uses a learning cycle that allows students to process information, analyze situations, and construct their own understanding of chemistry concepts. Our presentation will discuss how simple manipulatives and inexpensive software can be used for POGIL activities with high school students. The activity we will discuss uses observations from laboratory activities, teacher constructed magnetic molecular models, and Spartan generated models to develop the concept that intermolecular forces determine the physical properties of molecular compounds. Student created animations that demonstrate their understanding of the relationship between molecular polarity and intermolecular forces will be presented. Also, student interpretation of lab phenomena will be discussed.
