Matter: Properties, Classification, & Changes Phenomena-Based Lesson: Supercritical Fluid Extraction of Caffeine from Green Coffee Beans Presentation | Chemistry | Grades 9–12

This is the student-facing slide presentation that introduces the phenomenon, walks the class through observations and driving questions, and frames the evidence students will use for the Phenomena-Based Lesson in the high school Chemistry (grades 9–12) chapter Matter: Properties, Classification, & Changes, built around the phenomenon Supercritical Fluid Extraction of Caffeine from Green Coffee Beans. It is sold separately from the other two parts of the set.
