In this blog, Michael Jansen considers the significance of using proper units and their role in helping students develop a conceptual understanding of Chemistry.
Light absorbance and fluorescence were studied for a sample of the Chicago River that had been dyed green for St. Patrick’s Day. The sample had weak green fluorescence, showing that the intense green appearance of the river was in part due to the long path length of light through the water. The ability of the green color to partition into 1-octanol was also explored.
AP teacher and exam reader, Nora Walsh, shares tips on how to help your students answer AP Chemistry free-response questions. She provides examples, references, and rationale for her suggestions.

Short descriptions of demonstrations that can be connected to glaciers. Many of these examples are suitable for use in high school and collegiate General Chemistry courses and other courses such as Environmental Chemistry.
In this post, a veteran AP Chemistry teacher explains his rationale for the course's topic order. By using an empirically driven sequence, students build deep conceptual understanding and rely less on memorization of facts. It’s a must-read for any educator aiming to make chemistry more meaningful—and more memorable—for students.
In this post, Kevin Morse outlines an easy-to-implement procedure to help students reflect on teacher feedback for improved understanding.
In this blog post, Anthony Stetzenmeyer describes several ways he has started to use AI (Chat GPT) in this chemistry classroom. Anthony describes, in detail, ways AI can streamline lesson planning and help teachers maximize their prep time.
This post shares some previously posted resources on ChemEd X to help you plan a comprehensive stoichiometry unit.
Egg cartons and beverage holders can be used as models of atoms, with their dimples representing orbitals. Each dimple can hold up to two objects such as milk jug caps, plastic eggs, and cup pieces to represent electrons in the orbitals. Partially overlapping the trays by stacking the dimples represents chemical bonding and produces molecular models resembling Lewis structures. The models can be easily made from materials that can be readily found grocery stores and fast-food restaurants.
