Science Buddies do Drops on a Penny

We have a special time with each of the 2-3 classes to do science! They are learning about water too.

For this late October/early November series, we did drops on a penny with them. They did several trials, considered variables, and described what they observed.

Drops on a penny illustrates two important properties of water: water is cohesive– it sticks to itself and water is adhesive– it sticks to other things. Water’s stickiness is responsible for the way life on earth evolved. It has also driven the need for some inventions like towels and windshield wipers.
