Welcome to the Chemical Education Xchange (ChemEd X)! We hope to strengthen the community of chemistry educators by providing learning resources and forums for discussion and collaboration on our interactive platform. Take a look, and join in.
Check out the schedule for upcoming ChemEd X Talks along with recordings of past events.
It has been claimed that because all water ultimately ends up in the water cycle, we drink water that the dinosaurs peed out. What does chemistry have to say about this assertion?
Try out this though-provoking capstone demonstration for the Chemical Reactions unit!
Tissue paper can be folded and cut with chemistry-related patterns to make decorative paper banners that can be used as Mexican-themed decorations. Chemistry concept connections include lattice energy, bandgap energy, and ionic crystal fracture.
Nora Walsh asks Chat GPT to help create a list of potential phenomena to incorporate into lessons.
Nora Walsh reflects on her experience using phenomena in her chemistry courses and assessments for the first time.
Igniting paper towels that have been soaked in concentrated potassium nitrate and allowed to dry yields a flame reminiscent of that produced by guncotton. Repeating this experiment with other metal nitrates produces flames with different colors, plus a few other chemical surprises! This series of experiments is fascinating and connects to a wide variety of chemical topics including combustion, redox reactions, chemical thermodynamics, and flame tests. You don't want to miss this one!
