Stoichiometry Resources
Moles, mole ratios and stoichiometry have been frustrating topics for many of my chemistry students. The MOLE and Avogadro’s number get tangled up in other Chemistry jargon and students have stared at me like I am speaking another language. I have been around long enough to know this is a problem that many of us have faced. I have tried many ideas that have helped and I want to share a few.

Teaching Chemistry With a Whole New "App"titude. Intro Blog 1.0
Allow me to introduce myself, my name is Doug Ragan and I have been a high school chemistry teacher for fourteen years. Three years ago, I was approached by my high school principal and the conversation went like this,
Principal: "You are one lucky guy."
Me: "Really, why?"
Small Research Projects in the Chemistry Classroom
You may have read Sarah Kong's recent blog post on inquiry on this site. I thought I would give a description of one way I incorporate inquiry learning into one of the chemistry courses I teach.
The Half-Life of Facts: Why Everything We Know has an Expiration Date
Samuel Arbesman, a mathematician and network scientist, uses the idea a half-life as an analogy for the changes in human knowledge that science brings. He discusses both the changing rate at which new science is done and the speed at which old results are replaced by newer ones. The analogy is far from perfect, but it emphasizes some critically important aspects of the processes of science.
Who am I and what is Inquiry?
Who is Sarah Kong and why is she starting a blog for Chem Ed X about Inquiry?
Percent Composition of an Oreo Cookie
Whenever possible, I try to begin a topic with something my students are familar with. For the introduction of Percent Composition in my general chemistry course, I brought in bags of Oreo cookies. Seeing the bags upon entering class was a great attention getter. If you are looking for ways to add more inquiry to your chemistry course, this a an example of how you can experiment with giving up a little control. Try it and see how it goes.
