The June, 2018 issue of the Journal of Chemical Education contains an article that describes a simple, yet fascinating experiment that you and your students are going to love! It involves the use of butterfly wings from the genus Morpho. I obtained some of these wings and enjoyed experimenting with them. You will too!
Read Dr. Nakita Noel’s career profile describing her background and her current position as a Postdoctoral Research Fellow at the Princeton Research Institute for the Science and Technology of Materials.
Erica Jacobsen shares highlights from the January 2019 issue of the Journal of Chemical Education.
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.
The science behind the incredibly popular Scrub Daddy sponge is investigated. Part of the appeal of the Scrub Daddy sponge is that it changes from soft to hard depending upon temperature. This allows a single sponge to be transformed into a hard scrubber or soft sponge, depending upon the temperature of water into which it is placed.
Years ago, I took some wonderful material science workshops sponsored by ASM International. They did an amazing job of helping me add some more tools to my teaching tool kit. Materials are all around us and the workshop was a week long adventure into either creating a material science course or tying material science into existing curriculum. The chemistry of materials can easily be introduced into any curriculum.
The June 2015 issue of the Journal of Chemical Education is now available online to subscribers at http://pubs.acs.org/toc/jceda8/92/6. This issue includes articles on curriculum; assessment; inorganic chemistry; investigating galvanic cells & exploring LEDs; atomic structure; nanochemistry laboratories; physical chemistry in the lab; synthesis.
In this Activity, students investigate the physical properties of different balls that may look similar, but have very different rebound properties. Students also investigate how the rebound properties change when the balls are subjected to near freezing and near boiling temperatures. This Activity could be used at the beginning of the school year as an exercise in making observations.
In this Activity, students learn the general principles of serial and parallel nanofabrication techniques. Students use nylon spheres, contact paper, and talcum powder to form patterns. Using this macroscale analogy, students explore the parallel fabrication technique known as nanosphere lithography.
This Activity introduces students to the unique properties of nanoscale materials through exploration of size-dependent optical properties of gold nanoparticles. Students first prepare a solution of gold nanoparticles. They then investigate the solution’s use as an electrolyte sensor by adding a non-electrolyte and a strong electrolyte, and observing any resulting color changes.
