This collaboratively developed inorganic chemistry-based ethics case study has been designed for use with general science students (not necessarily chemistry or inorganic chemistry students). It could be used as part of a research ethics training program for undergraduates or as a stand-alone research group meeting on ethics or class assignment on data integrity. In this particular case study two data points are suspected of being in error because of a student mistake in labeling samples.
This is written for a freshman seminar course, "Nuclear Chemistry and Medicine," open to all majors. It meets once per week for one hour, and is meant to facilitate the transition into college for first-year students by providing an informal educational experience.
This paper from Chemistry: A European Journal by Manolis Manos and Mercouri Kanatzidis (link provided below in Web Resources) describes the ion-exchange chemistry of a layered sulfide (KMS-1) that exhibits an enhanced preference for soft metal cations (Cd2+, Pb2+, and Hg2+) replacing K+ in between the metal sulfide layers of KMS-1. Not only does this paper provide a practical application of hard-soft acid-base theory (HSAB), but it provides an accessible introduction to the technical literature for undergraduates, par
Several years ago I began using a set of Ligand-of-the-Week exercises in my Inorganic course to encourage (force) students to go outside of our textbook and into the chemical reference materials and chemical literature to find examples of ligands that bind to metal ions. My motivation was to get my students to see the wonderful breadth of known metal-ligand complexes and to develop skills associated with analyzing and classifying ligands. My original paper is fairly complete and can be accessed via J. Chem. Educ. which is now available through the ACS website.
Groups of 2-4 students (depending on class size) are each assigned a different collaborative project that involves using DFT calculations to evaluate some of the principles of inorganic structure and bonding developed in lectures throughout the semester. Each “project” involves comparing the computed properties (spectroscopic (IR), geometric,or relative energies) of a series of molecules and drawing conclusions about the observed differences using concepts developed in class.
This is a document that I hand out to every student I have, outlining what I
Students in the courses I teach (primarily general chemistry) have struggled with understanding the three representations of matter: macroscopic, particle, and symbolic. This is particularly evident when these representations extend into reactions. Additionally, students struggle with understanding basic concepts of aqueous solutions and, by extension, reactions in aqueous solution. This activity is designed to help the students recognize different types of representations and then generate these for simple systems.
I designed this lab experiment to introduce students to the uses of powder X-ray diffraction in the context of the synthesis of a technologically relevant material. Zinc oxide nanoparticles can be synthesized readily with reagents that are inexpensive and relatively benign with regard to student use and waste disposal. Two experiments described in J. Chem.
This is written for a freshman seminar course, "Nuclear Chemistry and Medicine," open to all majors. It meets once per week for one hour, and is meant to facilitate the transition into college for first-year students by providing an informal educational experience. It should be adaptable to a lecture-format course, and I will try to do this for my Junior-year Inorganic Chemistry.
