There are many ways that assessment can be done well. Michael Jansen shares what worked for him.
A trip to see the 2024 solar eclipse provided the opportunity to explore ideas associated with sulfur in petroleum, sunlight intensity measurements, laser interference patterns from eclipse glasses, and large-scale light emission from excited hydrogen.
Have you seen the "salting-out effect"? This interesting demonstration shows a separation of two layers in a solution of water and an organic solvent by adding an ionic salt. Although this concept has important applications in organic chemistry and biochemistry, it can also be visually stunning and engaging for audiences. Read on to learn how to incorporate this demonstration into your chemistry lessons.

Nora Walsh outlines the interactive notebook pages she uses for her unit on Solutions. All of the documents and foldables are available for download.
Part 3 includes further anthocyanin experiments to make a connection between the food we eat and the chemical principles that are employed to ensure that canned foodstuffs can be preserved properly. These recent studies have focused on the reaction of tinplate cans with iodine.
This activity allows for the simple and accurate determination of the heat of vaporization, ΔHvap, of water at 100°C, and ultimately the approximate strength of a hydrogen bond in boiling water, in kJ·mol–1.
Ariel Serkin shares an activity she has explored using natural acid base indicators with her food chemistry elective students.
The new edition of “POGIL Activities for AP Chemistry” is on track to be released next winter. Laura Trout offered a sneak peak of the new activities and improvements that have been incorporated into the new edition in our March 27, 2023 ChemEd X Talk. Watch the recording of the presentation!
