Food Dyes as Acid-Base Indicators

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.

Electrons as Waves?

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.

ChemEd X ChemBasics Talk - Gas Laws

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.

Analogy Experiment—Projectile Pennies with Rutherford

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.

Chemical Bonding and Naming with Nora Walsh

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.
