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.
Natural food dyes are being sold online and in stores that can be used as acid-base indicators. These dyes open up a host of possibilities for at-home and in-class. For example, these food dyes can be used as indicators in the quantitative titration of the Mg(OH)2 in milk of magnesia.
A simple demonstration for high school chemistry students is described which gives a plausible connection between electrons as waves and the shapes of the s and p orbitals. This demonstration may build a transition from electrons as particles to electrons as waves.
Gas Laws are an essential and easily accessible area of chemistry to understand. They can be an excellent foothold into the inner workings of chemistry. In this ChemBasics Talk, Daniel Radoff will be arguing for moving a discussion of gas laws earlier in the school year. He will provide some labs, handouts, demos, and other ideas for ways of teaching this engaging subject. Register for this (FREE) hour long Zoom meeting to be held December 9th at 8pm EST.
Atomic theory is a common topic throughout any introductory chemistry course. It is likely that Rutherford’s gold foil experiment gets at least some attention in your course. This simple activity gives students an opportunity to replicate Rutherford’s experiment through an analogy experiment that may allow for easier conceptualization of the experiment itself and provide additional support for model development.
Here is a quick and easy yet powerful experiment for para and diamagnetism that helps to provide evidence for quantum numbers.
In this ChemBasics Talk, Nora Walsh offers everything necessary to plan a unit on the topic of chemical bonding and naming including introductory and discovery activities, manipulative activities, practice problems, her favorite online teaching resources and more. Watch the recording and access resources she shared.
