Acid Base

I try to examine activities an multiple levels. First on the list, I want to know if my students will be engaged and learn something. Second, how difficult is it for me as a teacher to actually pull it off? One of the most important questions...are the students learning chemistry or just having fun?

ChemEd X recently made a Call for Contributions soliciting input regarding the big ideas being put forth by organizations like AP. The first thing that came to mind was a lab I modified that is centered around making connections between topics. Admittedly, this lab is not a "big idea" per se.

I recently stumbled across a blog about the use of BCA (Before Change After) tables for stoichiometry written by Lowell Thomson.  I was thrilled to discover ChemEd Xchange!  I wanted to share my journey, spurred on by my students, into the extensive use of the BCA

I have a first day routine that I am very proud of. I have used it for 25 years and I think I finally have it down pat. I have spoken to students from 20 years ago at reunions and they tell me that they still remember the first day of chemistry so I think it is pretty good.

Congratulations to Andres Tretiakov who solved Chemical Riddle #2. In this particular riddle, we presented a twist on the famous “Disappearing Rainbow” demonstration. You can purchase a

A student of mine, Anthony Shepherd, and I worked together to develop a new chemical riddle.  How do you think we performed the experiment in the video below?
