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).

CompChem 02: Introduction to WebMO

Submitted by Joanne Stewart / Hope College on Mon, 05/20/2019 - 10:11
Description

This is the second in a series of exercises used to teach computational chemistry. It has been adapted, with permission, from a Shodor CCCE exercise (http://www.computationalscience.org/ccce).

It was tested on WebMO Version 18 but should work with minimal modification on earlier versions. WebMO is a free web-based interface to computational chemistry packages (www.webmo.net).

Description

Part 9 of the Flipped Learning in General Chemistry Series. This video explores the concept of reaction rate and shows how the rates of change of reactant and product concentrations vary during the course of a reaction.

Hess's Law

Submitted by Kerber / Bucknell University on Wed, 05/15/2019 - 09:52
Description

Part 8 of the Flipped Learning in General Chemistry Series. This video shows students how to calculate the enthalpy change for an overall reaction by combining a series of individual steps.

Oxidation States

Submitted by Kerber / Bucknell University on Wed, 05/15/2019 - 09:45
Description

Part 7 of the Flipped Learning in General Chemistry Series. This video introduces the concept of an oxidation state, which is a tool used to keep track of electrons in chemical reactions.

Molar Mass

Submitted by Kerber / Bucknell University on Wed, 05/15/2019 - 09:35
Description

Part 6 of the Flipped Learning in General Chemistry Series. This video reviews the concept of the mole and shows how to use atomic masses of individual elements to calculate formula masses of covalent and ionic compounds. The video also introduces the concept of stoichiometry conversions.

Molecular Structure and VSEPR Theory

Submitted by Kerber / Bucknell University on Wed, 05/15/2019 - 09:22
Description

Part 5 of the Flipped Learning in General Chemistry Series. This video introduces valence shell electron pair repulsion (VSEPR) theory and teaches students to predict the geometry of a molecule from its Lewis structure.
