Molecular Orbital Theory: Flash Review

Submitted by Chris Durr / Amherst College on Thu, 06/06/2019 - 16:28
Description

This presentation is meant to be a review of constructing and utilizing an MO diagram, in this case O2. It's designed to be viewed as a powerpoint and printed out to keep for the student's notebook.

It can be used at multiple levels: as a review immediately after learning MO theory in general chemistry, or as a refresher before starting upper level inorganic chemistry. The instructure could add text or voice over the slides to add more detail or leave the presentation as is for students.

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.

Rates of Chemical Reactions

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.

Lewis Structures

Submitted by Kerber / Bucknell University on Wed, 05/15/2019 - 09:16
Description

Part 4 of the Flipped Learning in General Chemistry Series. This video introduces the Lewis structure, which is used to show the connectivity between atoms and the location of valence electrons.

Chemical Nomenclature

Submitted by Kerber / Bucknell University on Tue, 05/14/2019 - 15:50
Description

Part 3 of the Flipped Learning in General Chemistry Series. This video teaches nomenclature for basic inorganic compounds

Atomic Orbitals and Quantum Numbers

Submitted by Kerber / Bucknell University on Tue, 05/14/2019 - 15:44
Description

Part 2 of the Flipped Learning in General Chemistry Series. This video introduces the concept of the atomic orbital and the parameters that describe them.
