As I drive home from work every day in Houston, TX I am greeted by the entrancing voice of Dr. John Lienhard, now an Emeritus Professor of Mechanical Engineering and History at the University of Houston.

Curricular Alignment for Student Success
The February 2018 issue of the Journal of Chemical Education is now available online to subscribers. 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.
Whether you are looking to add a bit more scientific inquiry to your labs or simply looking for a great stoichiometry lab that can be added to your collection, I encourage you to try something like this with your students!
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.
Improving Student Perception and Performance
The December 2017 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: functional nanomaterials and chemical detection; improving student performance; peer-led instruction; simulations and computer-based learning; engaging and interactive instruction; synthesis laboratories; NMR spectroscopy and mass spectrometry; innovative physical chemistry investigations; ConfChem Conference on select 2016 BCCE presentations; from the archives: music and chemistry.
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.
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!"
