Making "Cents" of Surface Tension
Students explore the unique behaviors of water. They investigate surface tension using water drops on a penny and pennies dropped in a cup.
Curated OER
Surface Tension
Students study surface tension and determine if soap and heat will affect surface tension. In this tension activity students complete a lab, make a hypothesis and answer questions.
