In honor of the International Year of the Periodic Table: A familiarity with the chemistry of some of the elements more commonly encountered in everyday life is a valuable learning experience for all students. Sulfur is the fourth in this series of elements to be discussed as part of the Element of the Month program. #IYPT
It is not known why people develop allergies to nickel and there is no cure. The best course of action to prevent an allergic reaction is to avoid contact with products containing nickel. This article will explain how to make an easy and cheap nickel detection device that will limit or eliminate the risks of exposure to sources of nickel using some interesting classic chemistry.
Read Jason Kong’s career profile describing his background and his current position as a chemical laboratory supervisor for the Ohio Department of Agriculture.
The solution to Chemical Mystery #13: Bye Bye Blue! is presented. This experiment is useful to demonstrate to students when discussing acid-base indicators, neutralization reactions, or the acidity of carbon dioxide when it dissolves in water.
I’ve always been fascinated by advanced polymeric materials; it’s amazing how materials that are generally considered “plastics” have such stunning properties. I recently watched a couple of movies about Batman and it came out that some of his devices and protections are made of advanced polymers. In particular, the suit is almost entirely made of Kevlar.
This activity is designed to determine the concentration of Vitamin C (ascorbic acid) in a produce protector (in this case, Ball® Fruit Fresh) by an iodometric titration method.
If you want to lose weight, you have to burn calories. Anyone who has gone on a diet knows this. But when someone loses weight, have you ever wondered where the lost mass goes?
What happens if you cool a Scrub Daddy sponge in liquid nitrogen (or dry ice) and subsequently strike it with a hammer? Let's find out!
Decorative beads are tested for the presence of iron pyrite, or FeS2, in an activity well-suited for the National Chemistry Week theme of "Chemistry Rocks!"
The authors of the recent Journal of Chemical Education article, PolymerDay: Outreach Experiments for High School Students, offer a collection of interactive polymer activities designed to be part of an all-day outreach event for high school students. For teachers that might use the activities on separate occasions and/or as part of their curriculum, the authors recommend an accessible resource to support that work.
