The process of making beverages from fermented grain is a chemical synthesis slightly newer than human civilization itself. This article descibes the chemistry of the first step- malting the raw mature grain.
AACT has organized eight virtual symposia to provide professional development for teachers this summer. These symposia can truly help teachers plan for the next school year and virtually “see” one another to share ideas and concerns.
Liquid nitrogen is used to visualize the aerosol particles emitted while speaking, coughing, breathing, and sneezing. The ability of various masks to block these droplets was also tested.
The purpose of this variation on the “dragon’s breath” demonstration is to illustrate that face masks can diminish the movement of particles in the air, an important idea in public health.
Metacognition is a learner-focused evaluation of knowledge growth and an essential process for complete and lasting knowledge. Although virtual learning environments pose challenges for facilitating metacognitive activities, student-made videos are effective for increasing metacognition in online chemistry instruction.
Ice core science is truly cross-disciplinary as it draws extensively from chemistry, geophysics, geology, engineering, oceanography, microbiology, statistics, a deep understanding of historical events, atmospheric science, and climate science. And general chemistry topics include solubility, concentration, phase diagrams and changes, and stable isotopes in addition to many others. Let's take a first look at how ice core science can be used in teaching chemistry.
Learning How to Do Chemistry
The June 2020 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: innovative curriculum; exploring kinetics; engaging organic chemistry activities; molecular structure and symmetry; polymer chemistry; technology-based instruction; synthesis laboratories; undergraduate research experiences; from the archives: bath bombs and cosmetics chemistry.
Desmos offers an activity building feature that allows teachers to create and customize activities. The resource is applicable to a variety of science and chemistry topics and useful in whatever learning environment teachers find themselves in next school year.
