Penny Lab.

Today in class we experimented with surface tension. We counted how many drops of water would fit on a penny. That dome shape the water takes on as you add more water is due to water molecules sticking together and not wanting to let go. It was a fun lab with lots of smiles and good learning. At the end of the lab you were given a ‘mystery substance.’ Let me  know what you think the substance is below! Feel free to comment on other student’s comments. Have a great day.
