Abstract

In this work we discuss our experience implementing six hands-on wet-lab experiments designed specifically for at-home use during the pandemic. The experiments cover the concepts of classification of compounds, limiting reagents, spectrophotometry, equilibrium constants, and osmotic pressure. Student survey data on a method of presentation of the experiments using two cameras, and on the effectiveness of demonstration videos of the experimental techniques, which could be viewed by students asynchronously, are presented and discussed. Also discussed are considerations of cost and logistics in the development of hands-on at-home wet-laboratory experiments, and the potential importance of simulations or videos to complement them.
