The September AP Teach session focused on the application of Coulomb's Law in various sections of the AP Chemistry Curriculum and Exam Description (CED) and strategies for helping students write better responses.

What if your students derived the periodic table’s masses before they ever learned about moles? This piece reframes “classic” atomic theory as a data-driven approach to building O:C ratios, uncovering the law of definite proportions, and explaining why oxygen’s relative mass is 16 when carbon's is 12. The result is a historically grounded, quantitative model of Dalton’s ideas that makes atomic theory feel discovered—not delivered.

What if the key to better chemistry review wasn’t more class time—but less lecturing? In this article, Sarah English shares how creating short, targeted videos transformed her exam prep process and helped her meet students where they are. With printed notes, embedded questions, and thoughtful accountability, Sarah's flipped classroom approach turned passive review into active learning—and made her teaching life a lot saner.

What happens when chemistry and illusion collide? In The Disappearing Rainbow, a simple acid–base demonstration transforms into a spellbinding performance. With a single pour, colorless liquids bloom into a vibrant rainbow—then vanish in an instant. Now, with the arrival of the “Assassin’s water bottle,” this classic demo gets a modern twist that makes the magic easier (and cleaner) than ever.

The August AP Teach session focused on beginning a new school year with a review of student performance on the 2025 AP Chemistry exam. Jennifer Cambre shared ideas for how to interpret and analyze the data from the Instructional Planning Reports.
