June 2017 JCE issue

Erica Jacobsen shares highlights from the June 2017 issue of the Journal of Chemical Education that are of special interest to high school chemistry teachers.

Acid, Base, pH and Food Chemistry

Muffins

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? This is the first year I have attempted the following activity.  tudents were engaged in the real world connection, they asked questions, it transitioned into some chemistry concepts and even some parents got involved. The activity involved acid, bases, pH and food.

Time required: 

An evening of baking (about an hour at home) and a day in class.

Reduction of Permanganate Ion by Acids in Rhubarb, Apples, and Candy

Apples

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...

Qualitative Analysis of IONS

Near the end of the school year we are all thinking about what we will do with our AP Chem students until the end of the semester. Last year I wrote about a post AP independent study activity that I use dealing with transition metal compounds. I still like it and use it. But this year I want to talk about a very involved lab that many of my colleagues are ignoring.

A Review of "A Global Warming Primer"

In “A Global Warming Primer”, Jeffrey Bennett provides a template for conversation about the most pressing global environmental issue of our time. The author also recommends a link to the ACS Climate Science Toolkit that offers many useful resources for learning about and teaching the concepts related to climate science.
