Penny Lab

While studying the Scientific Method we looked at the miniscus on the surface of a penny when we added liquid to it. We wanted to discover how many drops of liquid could sit on the surface without overflowing. The variable was water, and then we added liquid detergent to the water to see if it changed the number of drops that could be added to the penny. Just ask one of our sixth graders to see wwhat the results of this experiment were.
