Dye-Sensitized Solar Cell 2010

Submitted by Simon Garcia / Kenyon College on Tue, 08/03/2010 - 16:37
Description

In this laboratory experiment, students construct a solar cell from a combination of synthetic and natural materials. It touches on a variety of chemical principles (kinetics, photochemistry, electrochemistry, intermolecular forces, material properties); however, the primary aim is the experience of turning materials into components and then assembling them into a working device. This experiment is unique in that it emphasizes each material's function, and how its properties affect this function. Students can seal these solar cells and take them home afterward.

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

12 Slides About African American Contributions to the Chemical Sciences

Submitted by Sibrina Collins / College of Arts and Sciences at Lawrence Technological University on Wed, 07/21/2010 - 23:53
Description

This presentation provides a brief overview of the contributions of five AfricanAmerican chemists, including two inorganic chemists. George Washington Carver is quite often themost celebrated African American chemist (soil chemist), but he is only one individual! There are many other African Americans that have made important and significant contributions to the chemical sciences. The profiles include inorganic chemists, namely, Professor Gregory H. Robinson, University of Georgia and Dr. Novella Bridges, Pacific Northwest National Laboratory (PNNL).

Molecular Origami: Precision Scale Models from Paper, by Robert M. Hanson

Submitted by Randall Hicks / Wheaton College on Tue, 06/29/2010 - 11:54
Description

This book called to me given my fascination with both origami and molecular model kits. While not a textbook in the true sense, the content of the book is pertinent to topics of molecular structure and symmetry and is therefore potentially valuable in both general and inorganic chemistry courses. In addition to the plans for constructing all the models (~125), there is a small amount of background information. Granted, many of these models could more easily be made using traditional model kits, but I had fun building them from paper.

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

Periodic Table of Haiku

Submitted by Adam Johnson / Harvey Mudd College on Thu, 03/18/2010 - 16:45
Description

This is a great website that was forwarded to me by a friend.  Broaden students' scientific communication skills by condensing the descriptive chemistry of an element down to a haiku.

Video explanations and practice problems of basic chemistry and math topics

Submitted by Lori Watson / Earlham College on Wed, 02/24/2010 - 15:34
Description

This is a website which links to a wide variety of good quality YouTube mini-lectures on basic topics in chemistry, mathematics, physics and a variety of other sciences.  Each video is about 10 minutes long and many go through example problems slowly and completely.
