Teaching General Chemistry: A Materials Science Companion

Submitted by Maggie Geselbracht / Reed College on Mon, 07/26/2010 - 18:15
Description

This book was originally written (full disclosure: I am one of the co-authors) for college teachers as a resource text to encourage and support the incorporation of more solid state and materials chemistry into the general chemistry curriculum.  The Companion, as I refer to it, is filled with background material, demonstrations, laboratory experiments, and end-of-chapter problems that will aid the non-specialist in enriching their teaching with examples from the world of solid state materials.  Although intended for a general chemistry audience, several of the chapters present fairly sophis

Battery in class activity

Submitted by Sheila Smith / University of Michigan- Dearborn on Wed, 05/26/2010 - 13:10
Description

This is an in-class exercise to be used at the end of General Chemistry (II).  I use it as a capstone exercise at the end of my second semester genchem course, but it would also make an excellent introductory review exercise at the beginning of a junior level inorganic course.  It provides an excellent review of topics from the entire semester (electrochemistry, acid-base, thermodynamics, colligative properties, solution chemistry and calculations) and shows how they are inter-related in a real world application (a car battery).

The Chemmies: A Descriptive Chemistry Audio/Video Research Project

Submitted by Neal Yakelis / Pacific Lutheran University on Mon, 03/29/2010 - 01:31
Description

This project was initiated as a way to enhance the descriptive inorganic chemistry unit presented in our General Chemistry II curriculum.  As the time available in the term prohibited the amount of lecture time needed to cover this vast array of material, the idea of a research project allowed for students to investigate an inorganic chemistry topic of keen interest to them over the course of the semester.  A previous term's attempt using a research paper project was quite unpopular, so the idea of a multimedia presentation was devised as an alternative to achieve similar learning goals.  S

Basic Chemistry Review

Submitted by Adam Johnson / Harvey Mudd College on Mon, 07/13/2009 - 14:32
Description

This website is a self-paced review of concepts for gen chem and includes test questions (and answers) for the reader.  It would be a great site to point your intro chem students to if they want/need extra review.  It is a set of 10 units, covering things like stoichiometry, unit conversions, and basic acid-base chemistry.  

Materials Chemistry: UW MRSEC Library of Slide Shows for Class Presentations

Submitted by Maggie Geselbracht / Reed College on Mon, 04/13/2009 - 17:43
Description

The Interdisciplinary Education Group at the University of Wisconsin Madison Materials Research Science and Engineering Center (MRSEC) has a fabulous website with a wide variety of great resources for teaching about materials and the nanoworld at all levels.  A favorite "corner" of this website that I refer to a lot in my own teaching is the library of so-called Resource Slides on a variety of topics.  These Resource Slides are divided up into 36 topical Slide Shows and include wonderful graphics to use in class presentations.   Slide Shows include:

Open-ended Recrystallization Addition to the Traditional M(acac)3 Laboratory

Submitted by Hilary Eppley / DePauw University on Fri, 04/03/2009 - 10:14
Description

In this open-ended activity, students design crystallizations to can see who can grow the biggest crystals of their colorful products. This addition is something that I add to the standard M(acac)3 syntheses that many of us do as an introductory lab in an upper level course or as a final lab in an introductory type course. Syntheses of the M(acac)3 starting materials are available in most published inorganic laboratory manuals.

Polarizing Power of Cations

Submitted by Nancy Williams / Scripps College, Pitzer College, Claremont McKenna College on Tue, 02/24/2009 - 20:08
Description

This is a handout which I use in an advanced general chemistry course, but which could be used in an inorganic course as well. It is a mini-periodic table with common cations and their charge to size ratios expressed as Q/r2, where Q is in integer charges (+1, +2), and r is in Angstroms. Conveniently, Na+ is an easy to remember 1.0, and Al3+ and Be2+ are easy to remember values of 10. This corresponds to the polarizing power of these ions, and is a crude proxy for how covalent their interactions with a given anion tend to be.

Identifying residual solvents

Submitted by Joe Fritsch / Pepperdine University on Thu, 06/26/2008 - 14:50
Description
Identifying residual solvents is important in helping students to interpret their NMR spectra and in the preparation of elemental analysis samples.  I have found the NMR work of Gottlieb and Nudelman to be valuable in my research and the teaching lab. The tabular data for many residual solvents in common NMR solvents for both proton and carbon spectra has been extremely valuable. Interpreting an NMR spectrum containing a residual solvent becomes  easier when the chemical shifts and multiplicity for the solvent are known.
