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!
JCE ChemEd Xchange provides a place for sharing information and opinions. Currently, articles, blogs and reading lists from ChemEd X contributors are listed below. We plan to include other items that the community wishes to share through their contributions to ChemEd X.
The unit of acids and bases is difficult for most students in Advanced Placement Chemistry. The variety of various calculations can be overwhelming. The Acid Base Speed Dating Activity engages students in completing a series of problems. Each student is assigned a specific solution and then determines their individual pH to complete their personal “Solution Biography.” Then the speed dating begins! For each date, the students need to find a specific match and determine their combined pH value.

Erica Jacobsen shares highlights from the February 2018 issue of the Journal of Chemical Education.
In an effort to align my lessons with the Next Generation Science Standards (NGSS), I have tried to take the content I have traditionally taught, and shift the design to focus on student engagement with the science and engineering practices outlined in the standards. For the topic of heat transfer I re-packaged the ice melting blocks discrepant event as a NGSS investigative phenomena.

Topics featured in this issue include: diversity within the classroom; assessment and curricular alignment; innovations in laboratory curriculum; electrochemistry; analytical chemistry labs; exploring materials science; engaging teaching approaches; historical perspectives; distilling the archives: lab-on-a-chip and microfluidic devices.
The concept of the mole has always been a challenging topic for myself and my students. The challenge comes in part when we try to imagine 6.02 x 1023 of anything. Another challenge for some students is the math and theory behind this number and concept. I have tweaked an activity to help guide my students to an understanding of these concepts.
Do you require your students to learn all the element names and symbols? Do your students struggle with chemical nomenclature, chemical equations, or stoichiometry? You may want to consider getting them back to the basics.
