The Empirical Formula of Magnesium Oxide Lab: A Successful Failure, Next Steps—and an Important Lesson

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.

Rocketbook Technology

Rocketbook is billed as ¨The last notebook you will ever buy¨. In short, that statement could very well be true. A Rocketbook consists of a notebook of specialized paper. 

Microplastics, Liquid Nitrogen, and Iodine: Polystyrene vs. Starch Foam Packing Peanuts

The differing electrostatic and solubility properties of starch and polystyrene foam packing peanuts are used in various demonstrations to describe aspects of microplastics and their interactions with the environment. Their differing responses to exposure to liquid nitrogen and iodine solutions are also described.

A Highly-Scaffolded Activity for Helping Students Generate Exam Review Questions and See Patterns in Quantitative Problem Solving

Helping students develop abstract understanding is a universal goal. This article describes an activity that involves students developing and then solving novel quantitative chemistry problems following a MadLibsTM style framework.

No Throwing Snowballs

To the point; no fluff. Communication so succinct that the message lands. Pardon the pun to Chemistry, but too many words dilute a message. The result: students remember nothing.
