Special thanks to Mr. Frank for guiding students through the Lesson 29 PowerPoint.  The lesson follows up on learning from Lesson 28, with students working in the same groups of four to hypothesize how unknown compounds will smell based on the properties of compounds studied in the previous lesson.  Students are welcome to retrieve the Lesson 28 worksheet they turned in yesterday in order to complete the Lesson 29 worksheet.  Both should be turned in at the end of class.  For homework, students should complete Lesson 29 textbook questions #3-7.

Reminders:

1. Use the wafting technique when sniffing the new compounds.
2. We do not have access to butyric acid at school, but rest assured, it smells awful (putrid – literally like vomit).  Learn more about butyric acid at wisegeek.org.
3. Please save the tubes for Ms. Schulze’s 4th period chemistry class.
