Teaching Guide | Osmosis and Medicine: Why Is Saline Used for Intravenous (IV) Fluids?
This teaching guide helps educators integrate the Osmosis and Medicine simulation into an advanced high school biology lesson. Students investigate how osmosis drives water movement across semipermeable membranes by collecting and analyzing experimental data, determining unknown solution concentrations, and applying their findings to explain why isotonic saline is used in intravenous (IV) therapy.
