Pennies and Water

This activity is pretty straight forward, each competitor will take a turn dropping water droplets onto the penny. Be sure the penny has no nicks on the edges. Count the number of drops for each competitor the person that gets the most drops wins! Science is interesting, we make sure that we try experiments more than once. If you follow the score sheet you will see that each player should get at least three turns. This is a great example of surface tension. Surface tension is the property where water will actually form a convex layer bending upwards and will act like a magnifier. Good luck! Click here for a score sheet.
