Phase, Size, Polarity, and Smell

Chapter 8 concluded with the Lesson 46 PowerPoint and Lesson 46 Worksheet.  Lesson 46 brought together the various concepts needed to understand how molecules with certain properties can be detected by our noses, with our brain recognizing those molecules as having a specific smell.  The entry task (ChemCatalyst) asks students to model why perfume molecules can be smelled from across a room, but paper cannot (both placed near a sunny window).

Students also received a copy of the Chapter 8 Study Guide to use in preparation for the quiz on Tuesday.  Work through the quiz questions on your own, then compare your answers to the key.

Wondering how to determine whether a molecule is symmetrical or asymmetrical?  Work through the slide deck from Dr. Fred Omega Garces and focus in on slide 15.  Look familiar?  Students received a copy of this flow chart in class today.
