I previously wrote about an experiment published in the Journal of Chemical Education called “Hydroglyphics”1.

Chemistry classroom accidents have been in the news too often recently. I hazard to suggest that there are smaller incidents that never make the news because there are luckily no serious injuries. We need to be vigilant in our safety concerns to protect our students and ourselves from any accidents and exposure to hazardous substances. We also need to be aware of theft concerns. Unfortunately, students may be looking for ingredients to experiment with explosives or to manufacture illicit drugs.

Making plans for back to school? Don’t forget the candy! It doesn’t sound like something a nutritionist would recommend, but what about a chemistry educator?

Earlier this week, I saw a tweet showing a compilation of apps entitled the Periodic Table of iPad apps  (https://sjunkins.files.wordpress.com/2014/06/iste-posters-001.jpg).

One day during class I presented the disappearing rainbow demonstration and explained the chemistry behind it. After doing so, I had a student ask me if a particular bartending trick called “rainbow shots” was done in a manner similar to the way the disappearing rainbow demonstration is performed.

I just finished reading in the June 2014 edition of JCE. He hits on a touchy subject between college chemistry instructors and their students...the grade.

Here is something to ponder as you think about your lab experiences this year:  I have been using an excellent inquiry lab for the past few years.  I think it does a fabulous job guiding the students through the amazing (yet often dull to students) world of specific heat equations and learning about calorimetry.  However, this semester, I returned to the old, traditional calorimetry lab.  I wan

I was looking for a new demonstration to initiate a discussion about polarity and related properties to use as part of an exam review. I found a . It is entitled “” (see note below). I have placed both solutions together before, but I had not added the squares. The demonstration fulfilled my needs. I could have used the original video and muted it if I had not had hexane to demonstrate with.

“It sort of started to look kind of like a very pale blue.” A friend who teaches at the middle school level told me about a science experiment he’d done with his students. The procedure suggested to students that a particular solution would turn blue, but also asked them to write down what they saw happen. The thing was, it wasn’t actually designed to turn blue.
