Comparing Homonuclear and Heteronuclear Diatomic Molecules with WebMO

Submitted by Catherine McCusker / East Tennessee State University on Wed, 11/04/2020 - 13:07
Description

Students first learn the basics of WebMO by building and optimizing 2 small molecules. They then calculate and visualize the molecular orbitals of two diatomic molecules (N2 and BF) and observe how going from a homonuclear to heteronuclear molecule changes the shape of different molecular orbitals. 

As written this activity uses the WebMO demo server so no computational chemistry software/licences are required.

d-Orbital games

Description

This is a great site for chemistry fun while you learn. They have multiple games, most free if you want to print your own.The card game that I am using is 18.  It is played like 21 or blackjack but uses metal centers and ligands to get to 18.  A fun way to teach 18 e- rule and familiarize students with ligands. My husband suggests using Dove squares instead of the optional benzene "chips" for "betting" which I think will make it very competitive.

Slap count also teaches counting 18 electrons.

Chemistry Icebreakers

Submitted by Anne Bentley / Lewis & Clark College on Sat, 08/15/2020 - 22:37
Description

We have developed a set of icebreaker activities that could be used at any course level, either in an online video chat or in a classroom. These are based on the popular Mad Libs game in which some words are left out of a story and players are asked to provide words to fill in the blanks without knowing much about the story. We've provided an introduction to the game, definition of typical parts of speech that are requested (ie, adverb, noun, adjective, etc), and three starter activities.

First Day Discussion - What Is Inorganic Chemistry?

Submitted by Amanda Reig / Ursinus College on Fri, 08/07/2020 - 21:21
Description

In 2019, the journal Inorganic Chemistry updated it's scope (https://pubs.acs.org/page/inocaj/about.html).  This updated scope inspired me to update my first day of class activity for Inorganic (which was typically a version of the excellent first-day LOs from VIPEr).  

I asked students to read the journal scope (web link or hard copy provided) and answer a few questions in small groups:

Easy and Inexpensive Conversion of Lab Safety Goggles to Face Shields

Submitted by Amanda Reig / Ursinus College on Thu, 08/06/2020 - 13:30
Description

In the time of COVID-19, a need for additional PPE in the form of face shields was deemed required for safe laboratory work when in the presence of other students and faculty.  An inexpensive method was devised to convert standard laboratory safety goggles into a face shield through the use of commercially available plastic report or presentation covers (sometimes called binding covers). This LO describes the fabrication process along with chemical compatibility and flammability testing of the purchased plastic sheets.

This is a short set of slides I use to introduce aspects of coordination chemistry for my foundation level inorganic chemistry class. 

Pre-Modern Chemistry: A Brief World History

Submitted by Shirley Lin / United States Naval Academy on Fri, 06/19/2020 - 10:40
Description

This Powerpoint presentation was developed to support diversity, equity and inclusion (DEI) in the chemistry classroom. One of the challenges of modern chemistry (and other modern STEM fields) is that the history discussed in general chemistry textbooks often focuses on achievements by Western scientists. While the most prominent chemists in the area of modern atomic theory were privileged, Western white men, their ideas were influenced by centuries of chemistry practiced by peoples across the globe.

Fostering a Growth Mindset: Inspiring Belief

Submitted by Anne Bentley / Lewis & Clark College on Tue, 06/09/2020 - 13:25
Description

I developed this short class component in response to reading Saundra Yancy McGuire’s book, “Teach Students How to Learn.”  One chapter focuses on the importance of mindset, a concept developed by Carole Dweck. Students with a growth mindset believe that they can learn how to learn challenging material, while students with fixed mindsets believe that ability is innate and unchangeable.

s-p Mixing and the Order of MOs in Diatomic Molecules

Submitted by Michelle Personick / Wesleyan University on Fri, 06/05/2020 - 20:13
Description

These slides provide an introduction to s-p mixing in diatomic molecular orbital diagrams appropriate for students in a general chemistry course.
