Fifth and sixth graders learn about surface tension

March 1, 2017

Hands on act ivies are always the most fun! Fifth and sixth graders started off their surface tension lab by making charts and predicting how many drops of water would balance on a coin before the surface tension broke. They noted what coin they were trying, if it was heads or tails up and how many drops of water they thought it would hold. Then came the fun part. Using eyedroppers they very carefully added water to the coin, counting each drop as they went. As they worked up from dimes to pennies to nickels to quarters their ability to predict the number of drops improved. Students agreed that the lab was a great way to learn.
