Osmosis and Potato Experiment Questions

Mr. Anderson guides students through an osmosis lab, often called the potato lab. The lab involves using potato cores and different sucrose solutions to observe changes in mass over time. Students learn to prepare potato cores, set up the experiment, and measure mass changes. The lab emphasizes careful setup and measurement to ensure accurate results, with a focus on understanding osmosis through percent mass change.
