Introduction to reactions of ions with water

Submitted by Michelle Personick / Wesleyan University on Wed, 06/23/2021 - 12:08
Description

This is an in-class activity that I use in my advanced general chemistry course right before I start teaching about the relationship between the Bronsted acidity of cations and their hydration/hydrolysis. This is the first topic in the course (reactions of ions in aqueous solution), and we would have just spent a lecture reviewing intermolecular forces. 

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.

Recorded by VIPEr Fellows Tendai Gadzikwa, Kari Young, and Dean Johnston with Hilary Eppley (moderator) on April 9, 2021.  The full nanoCHAt playlist can be acccessed at https://www.youtube.com/playlist?list=PL2wnHWA8OaA5Y6pPaOk2zt6wwrd2HK6kP

nanoCHAt #4: Leveling the Playing Field, part 1

Submitted by Shirley Lin / United States Naval Academy on Wed, 04/28/2021 - 13:26
Description

A nanoCHAt conversation about ways that instructors can level the playing field for students coming into a course with a variety of academic backgrounds. Recorded by VIPEr Fellows Kate McCusker, Abdul Mohammed, Janet Schrenk, and Andrea Van Duzor with Shirley Lin (moderator) on April 2, 2021.  The full nanoCHAt playlist can be accessed at https://www.youtube.com/playlist?list=PL2wnHWA8OaA5Y6pPaOk2zt6wwrd2HK6kP

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

nanoCHAts: Informal conversations about teaching

Submitted by Hilary Eppley / DePauw University on Wed, 04/07/2021 - 14:33

A collection of all of the IONiC VIPEr NanoCHAts. These are short discussion on a teaching topic by 4-5 faculty members from different institutions. Each of these events is recorded and posted to the IONiC VIPEr YouTube Channel.

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

Submitted by Kyle Grice / DePaul University on Thu, 02/18/2021 - 18:09
Description

Dr. Sabrina Sobel of Hofstra University Presented the 16th SLiThEr (Supporting Learning with Interactive Teaching: a Hosted, Engaging Roundtable) on 2/17/2021. The topic was scaffolding and oral exams in general chemistry. 

The SLiThEr was recorded and posted on YouTube. The link can be found below. 

Introduction to batteries

Submitted by Abby O'Connor / The College of New Jersey on Thu, 01/07/2021 - 13:56
Description

A little more than 5 slides.... but hey batteries are important! Often there are not good slides available to introduce batteries, broadly, so I went a made them! These slides were also created to accompany the LO on redox flow batteries. This set of slides reviews alkaline batteries introduced in general chemistry and transitions to more modern approaches to batteries including lithium ion batteries and redox flow batteries. This work highlights the 2019 Nobel Prize work for lithium ion batteries.
