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.
This is the link to the 14th SLiThEr (Supporting Learning with Interactive Teaching: a Hosted, Engaging Roundtable), presented by Sydney Towell and Reilly Gwinn and Hosted by Chip Nataro. The SLiThEr was recorded and posted on YouTube (see the web resources link).
This particular roundtable was presented by two senior undergraduate on their experiences during the pandemic. In addition to talking about the challenges or remote learning and research, they also discuss applying to graduate school and the apprehension they face making a decision without visiting the schools.
For our virtual offering of inorganic chemistry laboratory at Harvey Mudd College in Spring 2021, I made some videos and collected some high quality data (IR, 1H NMR, MS, UV-Vis, mp, and X-ray diffraction) that I will make available for my students. The videos show the synthesis of Co and Mn acacs, the difference between as-prepared and recrystallized compounds, making solutions for UV-Vis and Evans method NMR, and making Evans method capillary tubes. The procedures for the synthesis of these compounds is found in Woolins (either the first or second editions).
In this literature discussion, students are asked to explore the chemistry behind a eta-1 to eta-2 linkage photoisomer of sulfur dioxide bound to pentammine osmium. There are questions that tie to chemical structure and the nature of the two bonding modes of the ligand as well as an examination of the spectroscopic properties of the complex in the solid state. Two of the questions ask students to draw some conclusions based on their knowledge of periodic trends and the sigma donor ability of ligands.
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.
The activity allows students to present the results and analysis of a lab experiment in the form a research brief. Students have the option to create a written brief or record themselves giving the brief as a PowerPoint presentation.
This multi-part LO is a hybrid consisting of an in-class activity and a literature discussion. It utilizes the article "How to Review a Paper" by Igor V.
This paper in Chemical Science written by Ellen Matson and co-workers describes a structure function approach to improving the properties of non-aqueous redox flow batteries based upon polyoxovanadate-alkoxides (POV-alkoxides). Given the importance of battery technology on society and sustainable chemistry, this article allows students to engage with a paper that could have broad implications in society.

This particular roundtable focused on a reimagination of chemistry lab courses in the Age Of COVID and how to make chemistry relevant to non-chemists.

This particular roundtable was presented by Dean Johnston from the Otterbein website focusing on how the Otterbein website can be used in numerous courses for teaching symmetry.
