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 and ChemEd X ChemBasics Talks along with recordings of past events.
This Nobel Laureate crossword puzzle focuses on prizes awarded between 1901 and 1909. Learn and revisit some historical chemistry, terminology and background on key historical figures in this field.
Short descriptions of demonstrations and props that Dean Campbell has used while teaching his collegiate Environmental Chemistry course. Many of these examples are also suitable for use in high school and collegiate General Chemistry courses.
Exploring science claims found on social media helps students practice applying the claim, evidence, reasoning framework.
Sometimes the obvious is the most difficult to see. Even after teaching for four decades, there is still something to learn from students. What did I recently learn? Check out my post.
Find out how laboratory activities can be used as the starting point for scientific model development rather than as the endpoint, or verification, of concepts presented in lecture. This post deals with density.
Polystyrene foam sticks with a square or rectangular profile will not fit into a round target hole (e.g., the opening of a soda bottle) at room temperature. However, they do contract sufficiently in contact with liquid nitrogen to fit into the hole and produce a simple demonstration of Charles’s Law. Many other polymer foams do not shrink under these conditions, but still provide opportunities to discuss and explore their structure and chemistry.
