Reduction of Permanganate Ion by Acids in Rhubarb, Apples, and Candy
Tom Kuntzleman | Mon, 06/05/2017 - 17:00
If rhubarb stem is placed in a solution of permanganate, the purple permanganate ion is reduced to the colorless Mn2+ ion. It is thought that the oxalic acid present in rhubarb causes this reduction. The investigations presented in this post provide evidence that this may not be the whole story...
Use of Particulate-Level Instruction on Chemical and Physical Changes and States of Matter
Dan Meyers | Wed, 05/24/2017 - 10:36
I will share how I use the Target Inquiry activity, Change You Can Believe In. I have realized that I need to include particulate models within the assessments after the lab to fully evaluate my student's conceptual understanding.

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.
Chemistry in a Bottle
Tom Kuntzleman | Fri, 05/05/2017 - 07:06
Are you familiar with the dynamic density bottle experiment? This interesting experiment was invented by Lynn Higgins, and is sold by various science supply companies. Two immiscible liquids (usually salt water and isopropyl alcohol) and two different types of plastic pieces are contained within a dynamic density bottle. The plastic pieces display curious floating and sinking behavior when the bottle is shaken.
You Are Invited: Chemistry Instruction for the Next Generation
Deanna Cullen | Mon, 04/24/2017 - 20:47
ChemEd X and the Journal of Chemical Education (JCE) are collaborating to offer a virtual conference like most have never seen before. It is not a webinar. You do not have to schedule specific hours to view a live presentation. I think of it as similar to a virtual book/journal club with the added benefit of having the author leading it. In this case, authors were selected from among those who have published recent articles, activities and research in JCE on the topic of student-centered instruction in chemistry. The theme of this inaugural conference is Chemistry Instruction for the Next Generation.
