Helping Students with Visual Impairments See Colors

Submitted by Doug Balmer / Warwick High School on Fri, 05/31/2019 - 12:05
Description

I have had some students in class have a hard time identifying colors (flame tests, solution color, acid-base indicators, etc.) because of a visual impairment. There are many cell-phone apps that are helpful in aiding these students. "Pixel Picker" allows the students to load a picture from a device (cell phone, ipad). This is helpful because students are now dealing with a "frozen" image. Moving the cross-hair to different parts of the picture changes the R-G-B values. The "Color Blind Pal" app uses a more qualitative approach.

Teaching Computational Chemistry

Submitted by Joanne Stewart / Hope College on Thu, 05/23/2019 - 14:10

This is a series of in-class exercises used to teach computational chemistry. The exercises have been updated and adapted, with permission, from the Shodor CCCE exercises (http://www.computationalscience.org/ccce). The directions provided in the student handouts use the WebMO interface for drawing structures and visualizing results. WebMO is a free web-based interface to computational chemistry packages (www.webmo.net).

Inorganic Chemistry

Submitted by Anthony L. Fernandez / Merrimack College on Wed, 05/22/2019 - 10:42
Description

This course introduces the chemistry of transition metals and main group elements. Topics include theories of bonding, kinetics and mechanisms of reactions of transition metal complexes, oxidation-reduction reactions, hard-soft acid-base theory, and solid-state chemistry. Applications of inorganic chemistry to other areas (organic, analytical, and physical chemistry, as well as biology and biochemistry) are highlighted throughout the course. The laboratory portion of the course involves the synthesis and spectroscopic investigation of inorganic complexes.

Supramolecular Chemistry Videos

Submitted by Shirley Lin / United States Naval Academy on Sun, 03/03/2019 - 08:08
Description

The Rebek Laboratory homepage contains information on and molecular visualizations of a variety of host-guest systems developed by the research group over several decades. The theme behind this set of examples is the use of hydrogen-bonding to achieve self-assembly. Under the "Research" tab, one can find four videos with narration: an introduction to molecular assembly and three videos of specific examples of self-assembled host systems (the cavitand, the cylinder and the volleyball).

Advanced ChemDraw (2019 Community Challenge #2)

Submitted by Chantal Stieber / Cal Poly Pomona on Tue, 02/12/2019 - 12:12
Description

This in-class activity was designed for a Chemical Communications course with second-year students. It is the second part of a two-week segment in which students learn how to use ChemDraw (or similar drawing software to create digital drawings of molecules).
