Skype with a Scientist Live

This year so many in-person events at school have not been able to happen due to COVID restrictions. One activity that the author's science honor society students have enjoyed greatly is the Skype with a Scientist Live sessions. Students register in advance and then have the opportunity to be face to face with a scientist.

Effect of Temperature on Chemical Equilibrium using Copper Complexes

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.

Representation in STEM Education

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.

Photochromic glue and spring decorations

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.
