Creating an Organic Chemistry Reaction Pathways Flowchart as a Unit Summary

Student generated reaction pathways flowchart

For a recent unit on organic chemistry for my IB students, I tried something new. I gave them a handout with a list of organic compounds (by class/functional group) and a list of mechanisms and reaction types. Their task (in small groups), using either butcher paper or a large whiteboard, was to create a flow chart of reaction pathways.

CHEM Ed 2017 will be in Brookings, South Dakota on the campus of South Dakota State University from July 23 through 27. Currently the conference program directors are accepting abstract submissions through February 28th.   

Chemical Connections to Climate Change

It is becoming increasingly important for citizens to understand various concepts related to climate change and global warming. This post describes several chemical concepts that are pertinent to these issues, in the hopes that teachers of science and chemistry can introduce the topic of climate change into their classrooms and everyday discussions.

The Case of the Barking Dog

hydrogen test

To grasp the concept of oxidation and reduction reactions, I have my high school students write half reactions to show the loss and gain of electrons by the substances being oxidized and reduced. To help with this concept, I developed a quick lab activity involving the reaction between magnesium metal and dilute hydrochloric acid, which in turn led to the students collecting the hydrogen gas and then testing for its presence.

Mid-Year Reflections

It’s the end of one semester and the beginning of another. Final exam week. For the first time in my teaching career, I had my grades caught up and posted prior to the beginning of final exams. This gave me time to reflect and plan ahead.

Investigating the Effect of Concentration on Reaction Time

Concentration vs Rate of Reaction

Whether you are introducing collision theory or something more demanding like reaction order, the reaction between sodium thiosulfate—Na2S2O3 and hydrochloric acid can provide a consistent, accurate, and engaging opportunity for investigating these topics.

Introduction to the Claim, Evidence, Reasoning (CER) Framework


This webinar will introduce the Claim, Evidence, Reasoning (CER) Framework, implementation strategies, and how it helps create a classroom culture that more accurately reflects the ways progress in scientific knowledge and communication take place in the real world. Free webinar for all AMTA members!
