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
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)
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

Buffer solutions Virtual Lab
Description

This is a virtual adaptation of a buffer capacity lab experiment using the chemcollective digital workspace.  Students learn to make buffers in different ways and then test the capacity of their buffers to understand what makes an optimal buffer.
