Drops on a penny lab worksheet answers. Drops on a Coin - Science World Place a coin on a table or desk. Holding the eyedropper close to the surface of the coin, carefully squeeze water droplets onto the coin, one at a time. The droplets should pool up on the coin, creating a big droplet of water. Get the students to count the drops. Stop squeezing when the droplet on the coin breaks up and overflows. How Many Drops? - Lesson - TeachEngineering When water is dropped carefully onto the surface of a penny, it can pile up into a dome shape before spilling over the small lip around the penny's perimeter. Rubbing alcohol can pile up as well, but spills over before forming a well-rounded dome. Oil will not pile up much at all, as students discover.
