At our November meeting, Easing your way into CED Unit 4: Low prep, high engagement activities, we focused on low-prep, high-engagement strategies for AP Chemistry Unit 4 (Chemical Reactions), with an emphasis on helping students build conceptual understanding while preparing for AP-level rigor. The session highlights classroom-tested activities for net ionic equations, reaction stoichiometry, and solution stoichiometry, including labs, simulations, particle-level representations, and discussion prompts grounded in Johnstone’s Triangle. Designed to support both new and experienced AP teachers, these resources prioritize student sense-making while easing instructional planning for a traditionally challenging unit.
