Introduction to Strong and Weak Acid Ionization

Submitted by Sheri Lense / University of Wisconsin Oshkosh on Tue, 12/19/2023 - 17:09
Description

This is an in-class activity that introduces students to the concepts of ionization of strong and weak acids in aqueous solutions and equilibrium constants for acid ionization using two of the domains in Johnstone's triangle of chemistry knowledge, submicroscopic particle level illustrations and symbolic representations.

 

Atomic Orbital Representations and the Orbitron

Submitted by Andrea Van Duzor / Chicago State University on Fri, 06/09/2023 - 16:37
Description

This POGIL based activity is intended to review general chemistry concepts of atomic structure and to further those concepts with additional attention to d orbitals and radial distribution graphs.  The primary model in the activity is The Orbitron website (https://winter.group.shef.ac.uk/orbitron/) with students examining the isosurface and radial distributions for a variety of orbitals.

The Potential and Cost of Lithium-Ion Batteries

Submitted by Michael Drummond / Saint Mary's College on Thu, 08/04/2022 - 14:19
Description

These slides were originally developed as a part of an Earth Week presentation for a general audience, but can also be used as part of a general chemistry course or any course with electrochemistry. They provide a modern context and relevance to how lithium-ion batteries are produced and function. 

VIPEr Fellows 2022 Workshop Favorites

Submitted by Barbara Reisner / James Madison University on Sun, 06/26/2022 - 14:31

The second cohort of VIPEr fellows pulled together learning objects that they've used and liked or want to try the next time they teach their inorganic courses.

Basics of Redox Reactions

Submitted by Austin Scharf / Oxford College of Emory University on Wed, 05/26/2021 - 13:56
Description

This worksheet was designed as an in-class, group activity in a flipped classroom. It relies on an understanding of the octet rule and common charges of various elements, as well as basic nomenclature of ionic compounds.  The worksheet teaches students to balance simple redox reactions (in which only the oxidized and reduced atoms are present) by identifying half-reactions, counting electrons transferred, and multiplying half-reactions to "cancel" electrons.  

Basics of Qualitative Molecular Orbital Theory

Submitted by Austin Scharf / Oxford College of Emory University on Wed, 05/26/2021 - 12:23
Description

This is a worksheet designed for a flipped-classroom, in-class activity during the first course in our chemistry sequence.  It teaches the basics of Molecular Orbital Theory from a semi-qualitative standpoint, by showing the constructive and destructive overlap of s-orbital "wavefunctions."  The activity  illustrates the formation of the bonding and antibonding molecular orbitals in H2, shows its molecular orbital diagram, and introduces the concept of bond order.

SLiThEr #17: Demonstration of a Transition to a Remote General Chemistry Course

Submitted by Chip Nataro / Lafayette College on Mon, 04/19/2021 - 12:22
Description

Professors Kari Stone and Dan Kissel fro Lewis University describe the transition to a remote general chemistry course through a flipped curriculum using mastery-based grading. In particular, the development and implementation of a element project is discussed as part of the 17th SLiThEr (Supporting Learning with Interactive Teaching: a Hosted, Engaging Roundtable) on 3/4/2021

All Science is Either Inorganic Chemistry or Stamp Collecting (Rabinovich)

Submitted by Shirley Lin / United States Naval Academy on Thu, 04/01/2021 - 10:19
Description

This LO consists of some web resources for discussing chemophilately, the study of chemistry through postage stamps.

This LO is part of a special VIPEr collection honoring the 2021 ACS National Award recipients in the field of inorganic chemistry. Daniel Rabinovich was the recipient of the ACS Award for Research at an Undergraduate Institution for a career involving outstanding supervision and mentorship of undergraduate chemical professionals in synthetic inorganic chemistry
