Drops on a Penny
In this surface tension worksheet, students predict how many drops of water they can put on a coin. They test their hypothesis and repeat their experiment three times. They record their data and average their trials.

Paper Clip Sailing
Young scholars explain that some things can float on top of water because of what we call "surface tension." They see that if something happens to disturb these water molecules from tugging on each other, the skin-like surface breaks up.

Surface Tension On Coins
Students drop water onto clean coins to determine the tension of each coin and then to graph their findings.
Curated OER
Liquids and Gases
In this liquids and gases worksheet, learners will review the basic characteristics of water including surface tension and evaporation. This worksheet has 1 fill in the blank and 6 short answer questions.
