Polar Molecules and Smell

Entry Task

We continued our study of polarity, this time exploring how the polarity of molecules might impact our ability to smell the molecule.  Through the Lesson 45 PowerPoint, students learned that polar molecules are more likely to be detected by the nose as something with a scent although there are still polar molecules (like water) that do not smell.  Students worked in pairs to cut out the molecules in the molecules handout and used the molecules to complete the Lesson 45 Worksheet.
