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.

Density Bottles can be used to teach a variety of chemical concepts such as density, solubility, and polarity. In this post it is shown that Density Bottles can also be used to differentiate between heterogeneous and homogeneous mixtures, and to explore light scattering.
Polymer Concepts across the Curriculum
The November 2017 issue of the Journal of Chemical Education is now available online to subscribers. The entire issue is focused on polymer concepts across the curriculum. This special issue provides useful ideas and tools for chemistry instructors of all levels.
Links to a webinar and other resources to support the use of the Journal of Chemical Education as a resource for teaching and learning.
Check out the custom made chemistry swag I just purchased.
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!"
Celebrating the Value of Chemistry
The October 2017 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: geochemistry in action; research on effective teaching and study approaches; keeping education and chemistry relevant; communication and writing; spectroscopy; chromatography; synthesis; teaching resources; mining the archive: chemistry rocks!
Every day, one new peer-reviewed research article from any ACS journal will be selected to be freely available and remain open access for all to read. These articles are selected based upon recommendations by editors of ACS Journals and made available as a service to the global research community.
Check out these experiments that are very easy to perform and also related to the themes for National Chemistry Week in both 2017, Chemistry Rocks and 2018 Chemistry is Out of this World!
