Engage your students with this hands-on, inquiry-based lab exploring surface tension, capillary action, and the molecular forces behind them. Students test distilled, tap, salt, and soapy water on coins, then compare capillary action in different materials — modifying variables and drawing real-world connections. Includes: Pre-lab questions & hypothesesTwo adaptable experimentsData tables & analysis promptsCritical thinking extensionsPerfect for Chemistry, Biology, AP/IB Science, and NGSS-alig
