Chemical Kinetics with a Smartphone
Tom Kuntzleman | Mon, 11/25/2019 - 12:03
This experiment in chemical kinetics can be conducted using materials as simple as a smartphone, hydrogen peroxide, sodium carbonate solution, and blue food dye! The experiment is useful when discussing the order of rate laws with respect to reactants.
NGSS-ify Alka-Seltzer Rockets
Stephanie O'Brien | Tue, 02/19/2019 - 18:50
Given a guiding question, students determined what they wanted to test, did the experiment and got their CER boards ready for review. Instead of a regular argumentation session, we had a glow and grow session, where students had to provide positive and negative feedback for each board.
Are Diamonds Forever? A Chemical Investigation
Tom Kuntzleman | Fri, 11/02/2018 - 14:04
You are likely aware that diamonds are converted - albeit slowly - to graphite under normal conditions. Thus, diamonds don't last forever, in contrast to the popular advertising slogan. However, did you know that you can use chemistry to prove that diamonds are not forever? It's simpler than you think...
Disappearing X Lab

Erica Jacobsen shares highlights from the August 2017 issue of the Journal of Chemical Education that are of special interest to high school chemistry teachers.
An Activity to Demonstrate the Principles of Chemical Kinetics and Equilibria
George Parris | Fri, 08/04/2017 - 11:32
A classroom activity to demonstrate the principles of chemical kinetics and equilibria and the utility of the mole concept is described here. The activity involved no hazardous materials or complex equipment and can be enjoyed and appreciated by general studies students as well as chemistry majors.
Exploring the Diet Coke and Mentos Experiment
Tom Kuntzleman | Tue, 05/09/2017 - 07:39
I think this experiment provides a fantastic vehicle to involve students of all ages in small, hands-on and exploratory research projects. Like many others, my students and I have investigated various aspects of this interesting fountain.
Investigating the Effect of Concentration on Reaction Time
Ben Meacham | Tue, 01/24/2017 - 09:33
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.
Excellent Resource for Teaching Chemical Kinetics
Allison Tarvin | Sun, 01/15/2017 - 11:03
Chemical kinetics is one of the five challenge areas in AP Chemistry. My students and I have been working our way through one of the teaching and learning activities called Concentration vs. Time. The graphical analysis, guided-inquiry questions, and application to past and future content are seriously challenging, and my students report higher levels of understanding than in past semesters.
