Discovering Beer's Law by a Simulation-based Laboratory
Uses the PhET Beer's Law Simulation to derive Beer's Law. Students are instructed how to use the sim including a link to a video. Students then proceed to investigate pathlength, wavelength, and concentration. A link to a prebuilt Google Sheets spreadsheets allows for rapid plotting of the data and provides linear regressions and r-squared values. Post-lab questions use data collected in the lab to see if students have grasp the concepts in the activity. This data is provided by another link to a second Google Sheets spreadsheets.
The PhET project at the University of Colorado creates "fun, interactive, research-based simulations of physical... see more
