The purpose of this letter is to evaluate and validate the procedures described by Ford and Mason (February 2018 issue) using a microwave oven and chocolate bar to measure the speed of light.
Why does one attend ChemEd? Welllll (good Texas word!), one just never knows what is going to be shared. At this year's ChemEd in Brookings, South Dakota, at South Dakota State University, we suffered from curiosity.

This is a continuation of the Thought Labs used as review for AP Chemistry. This style of review allows to students to incorporate the skills they have acquired throughout their course experience in AP Chemistry while providing a platform for them to increase their comfort level in situations where they are asked to apply their learning to a new lab setting.

The catalytic oxidation of tartrate ions by hydrogen peroxide has been a staple of the Duke chemistry instructional program for many years. The demonstration clearly and colorfully brings to life the textbook description of what a catalyst is and how it enables a reaction to proceed at a faster rate by becoming involved in the reaction, yet in the end returns to its original state.
In this investigation, students will study the rate of burning of a candle as a function of the mass of the candle and as a function of the concentration, or partial pressure of O2(g).
Heat flow and temperature control are important topics in chemistry and chemical engineering. In a recent paper in Chem 13 News one of us (CM) analyzed the cooling curve of hot water in an insulated cup as an example of a first-order process.
The cost of everything keeps going up! What’s a laboratory science instructor to do when it comes time to place an order for chemicals and equipment for the next year? One solution is to find cheaper substitutes that can still achieve the desired student outcomes.
