Spectroscopy Lab Procedures and Concepts

Dr. Liz Hoffman introduces an AP Chemistry lab on spectroscopy, aligned with College Board standards. The lab includes structured activities, safety guidelines, and vocabulary. Teachers receive tips and troubleshooting advice. Students perform experiments to measure concentration using spectrophotometry, followed by assessments and opportunities for further study.
