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.

Examples of the explanation (students and teacher versions) are provided below:
After the lesson, students received the Chapter 8 Quiz Study Guide in preparation for the review tomorrow and the Chapter 7/8 quiz scheduled for next Tuesday.
