Day 19

Continuation of Lab 2 - Separation of Mixtures; today we analyze the original sample using paper chromatography.  As the chromatograms develop, we also went over the free response questions (FRQs) from Friday's Unit 1 Exam, in a manner similar to how the AP readers assess the FRQ section. 

Homework: Prepare for the start of the next unit on Atomic & Nuclear Structure by viewing the videos posted to EDpuzzle & reading sections 2.1-2.3 in the textbook.
