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
