This post describes a simple way to generate blue, green, orange, and yellow copper complexes, and to use these complexes to introduce students to the effect of temperature on chemical equilibria. The protcol avoids the use of caustic agents, allowing the experiments to be conducted by students as a laboratory-based investigation.

The diversification of STEM and STEM education is not going to happen overnight, but we all move it forward with what we do today. It is incumbent to us as educators to acknowledge and celebrate the different identities in our classrooms.

This post addresses concerns about the quality of the future of chemistry education in an online environment. 

The many colors of springtime can be illustrated with photochromic pigments in commercial products. These products include UV beads, and more recently, photochromic glue. The glue can be used as a photochromic paint for paper or even eggs. The resulting colorful, decorative objects can be used to illustrate chemical discussions of aspects of photochemistry.
