In 1848 Michael Faraday presented his Christmas Lectures entitled “Chemical History of a Candle” (Hammack and Decoste, 2016).

Heating and cooling curves are important visuals for chemistry students to understand when they are studying phase changes and thermal energy.

Many of us find stoichiometry to be what I like to think of as “the grind” unit in our chemistry courses. It feels like it never ends and the students can get very burned out with what can feel like repetitive practice. To address this, I designed a stoichiometry scavenger hunt to inject some fun into my stoichiometry unit.

Many of us are tasked with planning or teaching chemical quantities and stoichiometry. To support your planning, help you refresh your stoichiometry unit, or provide extra resources to use in your classroom, I have collected some favorite posts on stoichiometry.

The purpose of this article is to show how a microtitration can introduce Honors Chemistry students to titrations.

The disappearing rainbow¹ is a wonderful chemistry demonstration previously featured here on ChemEdX.^2-4 In this experiment, a colorless solution of NaOH is poured into a row of flasks, each containing a different acid–base indicator.

In 2015, I began making chemistry videos to reduce the amount of in-class lecturing during exam review. Some students needed a detailed reteach of specific content, others only needed a refresher, and still others grew frustrated when I retaught concepts they already understood well. Creating videos provided the flexibility to meet all of these needs.

I’m just old enough that I never kept a paper gradebook. When I was a student in school, my grades were on paper and arrived in the mail. As a teacher, my grades have always been entered into the computer and sent off to the world with a click of a button. Parents and students know the grade as soon as I share it. 

Formative assessment questions provide a useful lens into students' minds regarding what they are thinking about chemistry.

Introduction The proper and consistent use of units throughout calculations is of paramount importance in physical science. This should be inculcated in students from the first day of class. As chemistry educators, we must—without fail—model the proper, consistent use of units and significant figures.1

In February 2025 we discussed using particle diagrams, calculations, and titration curves to support student understanding of acids, bases, and buffers.  

I teach an introductory college chemistry course for non-science majors called Chemistry of Everyday Things. Most of my students have little prior science experience, and they often begin the course intimidated by chemistry.
