Take a Guess: How many drops of water can fit on one side of a penny? Part A: Perform a CONTROL test for comparison with later results. Step 1: Rinse a penny in tap water and dry …
We added an extra dimension to this classic lightning-fast science experiment by comparing how many drops of water fit onto each coin (penny, nickel, dime, and quarter) and tracking the data on a free printable table.
You can do this by adding soap, which is a surfactant, or material that decreases the surface tension of a liquid. In this experiment, you will prove that soap decreases the surface tension of water by putting water droplets on top of a …
