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.
This is an ACS Authors' Choice article and is open access to all.
A fantastic resource to help you learn more about how to teach climate change and global warming is described.
Students will be engaged in this activity that will help them make the connection between food and chemistry. Acid, bases and pH are addressed.
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...
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.
