JCE ChemEd Xchange provides a place for sharing information and opinions. Currently, articles, blogs and reading lists from ChemEd X contributors are listed below. We plan to include other items that the community wishes to share through their contributions to ChemEd X.

M&Ms as Isotopes

Use Mega M&Ms, M&Ms minis, and regular M&M’s in this activity to examine the concept of isotopes and average atomic mass. The color of the M&M’s represent that they are the same element and have the same number of protons. The size represents, in a relative sense, the different numbers of neutrons.

26th BCCE (July 2020): Call for Symposia and Workshop Proposals

The Biennial Conference on Chemical Education (BCCE) is one of the best professional development opportunities available for chemistry educators.
