Water Drops on a Penny Lab Mr. Which side of the penny will hold more drops of water: heads or tails? Worksheet will open in a new window.
This laboratory experiment (How many drops of water fit on a penny?) allows students to directly experience the abstract concepts of cohesion and surface tension.
As drops of water are added onto a penny, the adhesive force between the water and the penny keeps the water from falling off.
A helpful worksheet describes an interesting demonstration on the surface tension Learners guess how many drops of water the heads side of a penny will hold. I started this coin and water experiment by placing one of each coin (penny, nickel, dime, quarter) on a paper towel and asking the kids which coin they thought would hold the greatest number of drops of water. The oxygen end of water has a negative charge and the hydrogen end has a positive charge.
