Osmosis Lab Walkthrough

Mr. Anderson guides students through an osmosis lab, also known as the potato lab. The lab involves using potato cores and different concentrations of sucrose solutions to observe changes in mass over time. Students are instructed on the materials needed, how to set up the experiment, and how to collect and analyze data. The goal is to measure the percent change in mass of the potato cores after 24 hours. Mr. Anderson provides tips to ensure accurate results and explains the importance of labeling and covering the test tubes to prevent evaporation.
