You can perform an orange to black chemistry demonstration using materials commonly found in stores. The reaction appears to be similar to the Old Nassau reaction, but uses greener reagents. This is a great demonstration to do around Halloween time.

Inspired by a recent article in the Journal of Chemical Education, Tom Kuntzleman attempted to extract lithium from a coin battery, and to use the extracted lithium to produce a pink flame.
When introducing acid-base theory, the concept of indicators and their pH color changes is usually discussed. To illustrate some color transitions to students, a classroom demonstration has been devised based on a memorable scene from Disney’s 1964 movie Mary Poppins.
Michael Jansen reflects on a very common empirical formula lab that asks students to determine the empirical formula of MgxOy. He then explains how he continues to use it as a "successful failure", how he demonstrates an alternate procedure and leads his students to an important lesson.
A lab practical with an escape room story turned out to be a great final exam.
Beautiful, metallic mirrors of copper or silver can easily be formed in test tubes. Simply add the appropriate metal salt to a test tube, and heat! These reactions should be performed in a fume hood.
Chad Husting shares a microscale Reactions Lab and outlines his goals and plans for labs in his classroom as he prepares for next school year.
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.
In this lab, students connect the workings of an electrochemical cell in the lab with the symbolic equations used in electrochemistry and manipulate a model representing the particulate level of what is happening during the electrochemical process. Although this lab was previously highlighted on ChemEd X, there are now virtual options offered!
