Greendale Second Graders Show Their Cents!
Greendale second grade students participated in a science experiment to find out how much water the face of a penny will hold. No one thinks of a penny as holding water, but did you know they will hold several drops of water on their face? Students were asked to first come up with a hypothesis about how many drops of water would stay on a penny before it began to run off. Many guessed 5, 6, 10 drops. They were amazed when they were able to put 20, 25, 30 drops on a penny. They ended up learning that it is the surface tension of the water that allows such a large amount of water to sit on the face of a penny before spilling off. The students thoroughly enjoyed the experiment and left wanting to do more! They found out that science truly is FUN!!!!
