2023 Content Building Workshop - Morgan State University

Submitted by Chip Nataro / Lafayette College on Tue, 06/27/2023 - 10:56

This is a list of all of the learning objects developed in association with the 2023 content building workshop. Prof. Robert Gilliard was the featured speaker for this workshop, so most of the LOs will focus on his work.

Inorganic Chemistry

Submitted by Daniel Ashley / Spelman College on Thu, 06/22/2023 - 16:48
Description

Rigorous treatment of the chemistry of inorganic compounds, including structure, properties, and reactions, and their interpretation in terms of quantum chemistry, and solid state chemistry; analysis with modern instrumentation.

Examination and Classification of Molecular Symmetry

Submitted by Ben Lovaasen / Wheaton College (IL) on Thu, 06/22/2023 - 11:19
Description

This is a hands-on introduction to molecular symmetry and point groups. Students are not expected to have any exposure to molecular symmetry before this lab. Students work in pairs to identify symmetry elements in molecules and assign molecules to appropriate point groups.

Advanced Organic Chemistry (Spectroscopy)

Submitted by Fasil Abebe / Morgan State University on Wed, 06/21/2023 - 18:45
Description

The course covers the principles and methods at an advanced level in modern chemical analysis. Topic includes chemical structure determination, separation of mixtures, chemical methods, infrared spectroscopy (IR), mass spectrometer (MS), nuclear magnetic spectroscopy, and ultraviolet-visible spectroscopy (UV/vis).

A Strategy for Group Discussions of a Literature Paper: Roles That Rotate and Foster Different Skills

Submitted by Laurel Goj Habgood / Rollins College on Wed, 06/21/2023 - 12:12
Description

The "Lit Masters" concept is inspired by and adapted from one of my colleagues, Jenn Manak, in our education department. Students who are novices to reading the literature often are overwhelmed when assigned a paper to read and may struggle in group discussions. The strategy is to assign students to a semester-long group with designated roles for each paper that require them to produce a low-stakes artifact prior to class. During class time groups discuss the paper and it is followed with a debrief. 

Balloon Built Molecular Orbitals

Submitted by Darren Achey / Kutztown University on Wed, 06/21/2023 - 11:58
Description

In this activity, students will collectively build molecular orbitals for homonuclear diatomic molecules using balloons as models for atomic orbitals. This activity gets students up and moving and involved in the building of an MO diagram and allows for 3-D visualization of the core concepts of building molecular orbitals from atomic orbitals.

Inorganic Chemistry

Submitted by Jaime Murphy / Harding University on Mon, 06/12/2023 - 11:04
Description

CHEM 4310 is an in-depth review of modern inorganic chemistry. Topics will include symmetry, acids and bases, reduction-oxidation reactions, periodic trends, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and material chemistry. The course will meet for three hours of lecture and three hours of laboratory per week.
