Safety is job one

Submitted by Alice / Villanova University on Fri, 09/16/2016 - 13:12

This five slides about came to be from a discussion that happened after Marta Guron and Jared Paul gave a talk at the Philly ACS in Fall 2016. This is a modified version of a presentation given to all chemistry students regarding the proper handling and disposal of chemicals. Certain details will need to be modified to fit your individual institutions. The particular focus of the slides is for students to learn to turn to SDS sheets before using chemicals and to be able to read the labels on chemicals and understand the associated safety concerns.

Symbolize It All

Submitted by Fabiola BL / The Cooper Union for the Advancement of Science and Art on Wed, 07/27/2016 - 13:58

This is an HTML program that helps you spell with symbols of chemical elements for anything you want. Just cut and paste the text, paragraph or list of names you would like to "symbolize" in the left field. The program automatically displays the words that could be spelled with chemical symbols in the right field. When a word has more than one possible spelling, all of the possible combinations are displayed on a single line.

Developing a rubric for a learning object

Submitted by Joanne Stewart / Hope College on Fri, 07/08/2016 - 15:46

A rubric articulates the expectations for an assignment and enables faculty to assess student work in a rapid and consistent manner.

This Five-Slides About was developed for the TUES 2016 workshop Organometallica at University of Michigan. It was presented in conjunction with Chip Nataro's modeling of the development of a literature discussion learning object (Ligand effects in titration calorimetry from the Angelici lab).

Chemical Information Available on the Web

Submitted by Matthew Riehl / Minnesota State University, Mankato on Thu, 06/30/2016 - 22:21

This exercise introduces students to many chemical resources found on the internet.  Rather than being geared for upper-division chemistry majors, much of the material introduced is appropriate for freshmen and sophomore level students (although more advanced students will also benefit from the exercise).  The “web guide” contains links to many search engines and resources with brief descriptions of each while the “web report” has a number of exercises that asks students to search for chemical information.  The assignment is self-guided; students are encouraged to choose topic of interest t

Cyclic voltammetry animations

Submitted by George Lisensky / Beloit College on Thu, 06/30/2016 - 07:17

This is a question based approach for a discovery activity about cyclic voltammetry. The slider bar on a movie can used to control a variable and the displayed graph is updated to show the results. (You could also just play the movie to get an idea of what changes.)

The questions to be answered are

What is the shape of a cyclic voltammogram?

How are cyclic voltammograms affected by E0?

How are cyclic voltammograms affected by concentration?

How are redox equilibria affected by scan rate?

What if there are two reductions?

Close Packing Activity

Submitted by George Lisensky / Beloit College on Tue, 06/28/2016 - 11:47

Many extended structures can be viewed as close-packed layers of large anions, with the smaller cations fitting in between the anions. Larger holes between close-packed anions can hold cations with octahedral coordination. Smaller holes between close-packed anions can hold cations with tetrahedral coordination. The online jsmol resources show these layers and their holes.

Online Homework for a Foundations of Inorganic Chemistry Course

Submitted by Sabrina Sobel / Hofstra University on Mon, 06/27/2016 - 18:08

The Committee on Professional Training (CPT) has restructured accreditation of Chemistry-related degrees, removing the old model of one year each of General, Analytical, Organic, and Physical Chemistry plus other relevant advanced classes as designed by the individual department. The new model (2008) requires one semester each in the five Foundation areas: Analytical, Inorganic, Organic, Biochemistry and Physical Chemistry, leaving General Chemistry as an option, with the development of advanced classes up to the individual departments.

Solid State Stoichiometry Activity

Submitted by George Lisensky / Beloit College on Mon, 06/27/2016 - 17:11

The goal of this activity is to have students calculate the empirical formula of a compound given the contents of a unit cell. 

A repeating building block, or unit cell, is used to represent extended structures since shifting a unit cell along its edges by the length of the edge will exactly replicate the extended structure.
