German Chemist, August Wilhelm Hofmann first introduced the term "molar" (from the Latin moles, meaning "a large mass") into chemistry, around 1865. The particular use of the term molar gained currency in the physics literature, where it was in common use at least through the 1940s.

An outstanding chemical education system, which begins with educating future citizens and goes beyond the class room, is essential for an educated public, which is central to funding scientific research and technological development for the country. The focus is on the central role of chemical education, and how the ACS can better support…

The ACS (American Chemical Society) plays a major role in the facilitation of the teaching of established knowledge, the extension of this knowledge and public service, which become even more important because they are embedded in society highly dependent in its daily activities on the fruits of science and technology. The president of the ACS and…

This article discusses the author's observation that in his thirty-plus years in academics, many students who, by natural ability, interest, and work ethic, should have performed well in the sciences, but performed poorly. Many of these students are operating at the bottom rungs of Bloom's taxonomy (ladder), while college professors and industrial…

In a 2003 issue of the "Journal of Chemical Education," Kniesel and Bellamy describe a timely and pedagogically effective experiment involving breath-alcohol analysis using an FTIR (Fourier Transform Infrared Spectroscopy) spectrometer. The present article clarifies some of the information presented in the 2003 article.

The STArt! teaching Science Through Art program was developed to help both students and teachers address the new California Science Content standards. An initial presentation of program introduces molecular visualization using narrative discussions, handheld models, visualization software and art workshops and it also emphasize low-cost materials,…

Learning the connection between the roots and the chemical meaning of terms can improve students' understanding of chemistry concepts, making them easier and more enjoyable to master. The way in which using etymology to understand the meanings and relationships of chemistry terms can aid students in strengthening and expanding their grasp of…

Newly discovered biogenic organo halogens with an emphasis on the biologically active examples from marine organisms, bacteria, terrestrial plants and higher life forms, including humans, are focused. Organohalogen compounds represent a valuable and expanding class of natural products, in many cases boasting exceptional biological activity.

The appeal as natural antidepressant is the major selling point of St. John's Wort, which is referred to as "Prozac from the plant kingdom". Hypericin and hyperforin, two major constituents with significant biological activity of St. John's Wort and which are complex molecules with unusual features, are examined.

The fish poisons derived from plants used throughout the world, not only as piscicides but also for a range of other uses, including insecticident and in folk medicines, is presented. The aim of this review is to provide a useful background for students interested in natural products.

Overviews of the observations that constitute a structure proof for penicillin, specifically aimed at the general student population, are presented. Melting points and boiling points were criteria of purity and a crucial tool was microanalysis leading to empirical formulas.

A clinical study was designed and used to show the relationship of health and medicine, in a typical clinical scenario, where many chemical principles are involved and that an integrated knowledge of chemistry and biology is essential to the understanding, diagnosing and treating of illnesses. A case study would be a positive learning experience…
