The Chemistry Laboratory Curriculum (CLC) Innovators Program is now accepting applications for the 2026 cohort! This program offers institutional teams from across the U.S. the chance to participate in a week-long summer institute and ongoing virtual support meetings during the 2026-2027 academic year.
Curcumin, found in the spice turmeric, varies from yellow in acidic conditions to orange-red in basic conditions. This enables curcumin to be used in many acid-base demonstrations and incorporate ideas such as hidden messages and mechanochemistry.
Microtitrations can be used as a stand-alone lesson or as an introduction to more complex titrations. Done without expensive glassware and materials, this alternative to buret titrations is easy to implement in most classroom situations.
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.

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 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.
