A Visual Isotope Effect (a YouTube video)

Submitted by Dan O'Leary / Pomona College on Wed, 04/24/2013 - 17:46
Description

We have prepared a YouTube video demonstrating a visually accessible kinetic isotope effect in the Cr(VI) oxidation process, a reaction commonly encountered in introductory organic chemistry. The demo provides students with an opportunity to see an isotope effect and then understand how it can be used to provide mechanistic evidence for the identification of a rate-determining reaction step.

General Chemistry Electronic Study Aids

Submitted by David Kreller / Georgia Southern University on Sun, 04/21/2013 - 13:14
Description

At this website students can access interactive game-like learning resources that cover a wide range of topics in general chemistry.  These learning activities, which are in the form of flash cards, quizzes and matching games, will help student learn and review/drill important general chemistry topics.

Description

This website is a free and comprehensive resource that is a collection of open college courses that spans videos, audio lectures, and notes given by professors at a variety of universities. The website is designed to be friendly and designed to be easily accessed on any mobile device.

Energy Content and Properties of Fuels

Submitted by Matt Whited / Carleton College on Thu, 03/07/2013 - 10:59
Description

This is a group activity I developed for my "Introduction to Chemistry" class, which is set up primarily to cover the topics we consider to be prerequisites for the first course in our chemistry sequence at Carleton.  However, it covers aspects of thermodynamics (e.g., particularly Hess's Law) that are core topics for most intro courses.

Solid State Models with ICE Solid State Model Kits

Submitted by Nicole Crowder / University of Mary Washington on Mon, 01/07/2013 - 15:56
Description

In this in-class activity, students are broken up into teams of 4, which are then sub-divided into two teams of two for the building of the structures. The activity makes use of the ICE Solid State Model kits, and each group should have their own full kit.

The activity has 6 sets of structures for the teams to build; depending on the length of your class, you could have each team build all six sets OR have each team build one of the six sets to then share with the rest of the class.

A - HCP and CCP

B - Primitive cubic and CsCl

Atomic Orbital Display

Submitted by Flick Coleman / Wellesley College on Thu, 10/04/2012 - 12:26
Description

This is a jmol display of the atomic orbitals from 1s to 4f that can be rotated in space. They are plotted relative to the x, y, and z-axes.

Using the curated data sets from Wolfram Research in Inorganic Chemistry

Submitted by BoB LeSuer / The College at Brockport, SUNY on Wed, 09/19/2012 - 10:56
Description

Recent versions of Wolfram's Mathematica software have access to a variety of curated data sets that are relevant to Chemists.  This activity is an example of how one can use the ElementData dataset to develop an on-line tool to explore periodic trends.  Wolfram provides a free web-based platform (the FreeCDF plugin) to view and interact with specifically designed Mathematica files.  The activity can be accessed in one of three ways:

keeping a lab notebook

Submitted by Adam Johnson / Harvey Mudd College on Thu, 09/13/2012 - 23:19
Description

I found this great website linked from somewhere a few days or a week ago and already forgot where. But I am teaching organic lab this semester and convinced one of the students to do a little research. As a reward, I am going to buy her, and the whole class, gelly roller pens for keeping their notebooks.

This is a GREAT site that has so much detail on keeping a lab notebook. There is a lot of great stuff in there.

Home Built Equipment Links

Submitted by Chris Bradley / Mount St. Mary's University on Thu, 07/19/2012 - 15:09
Description

I am always interested in building/modifying equipment and glassware, and the following C and E News article led me to an interesting website, also linked, where details on building homemade rotators and stir plates are in place. Both models can be constructed with materials for less than $30. As I'm always looking to keep costs down for equipment like this, I thought I would share it. If anyone knows of other links, please let me know.
