Lab: Unique Properties of Water
Students will rotate through seven different stations during this lab to discover the unique properties of water including surface tension, cohesion and adhesion, polarity, density, capillary action and water's role as the universal solvent. This lab reinforces key concepts and scientific terms from your study of the Chemistry of Life and gives students the opportunity to practice laboratory procedures and become more familiar with common lab equipment.
