Erica Jacobsen shares highlights from the October 2017 issue of the Journal of Chemical Education that are of special interest to high school chemistry teachers.
The ACS Committee on Chemical Safety has released the 8th edition of "Safety in Academic Chemistry Laboratories". The publication provides advice for first- and second-year university students.
Erica Jacobsen shares highlights from the July 2017 issue of the Journal of Chemical Education that are of special interest to high school chemistry teachers.
HCl and NaOH, a strong acid - strong base titration? Citric acid and NaOH, a weak, triprotic acid - strong base titration? Do your students standardize the NaOH solution as a first step?
You probably know what happens when you place dry ice in water. Do you know what happens when dry ice is placed in acetone or glycerin? Read this and find out!
Have you ever wondered where the cloud comes from when dry ice is placed in water? If you think the answer is “atmospheric water vapor”, be sure to read this post because experimental evidence suggests that this explanation is wrong.
In the lab, students are given a 1.5 gram samples of copper. The copper is taken through a series of five chemical reactions ending with the precipitation of solid copper. After the five reactions, students are asked to return their 1.5 gram samples of copper to the teacher.
Learn a simple and very inexpensive way to build and use an "absorption spectrometer" using a smartphone. This is a great way to implement Beer's Law experiments in your classroom!
Think it’s possible to get nostalgic over paperwork? I just did, spurred by editor-in-chief Norb Pienta’s editorial Thinking about Champions in the December 2015 issue of the Journal of Chemical Education.
