Penny Perfect Properties (Solid-Liquid Interations)
I can get more water to stay on a penny than you can! Collaborative pairs determine the volume of liquids that can be contained on the surface of copper pennies and plastic coins. The pairs analyze their results using graphs and go on to...
Curated OER
Drops on a Penny
In this surface tension activity, 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.
Curated OER
Walking Magic
Students investigate surface tension using water striders. In this inquiry lesson, students develop a researchable question about the topic. They explain the environmental consequences of lowering water surface tension.
Curated OER
Surface Tension-Driven Flows
Students learn how surface tension changes can cause fluids to flow.
Curated OER
Surface Tension Grabbers
Students explore why surface tension is such a very important biological concept. Determination is made on why the myriad of biota that interacts at the air-water interface are vital components of aquatic and marine ecosystems. They...

Propel a Toy Boat with Chemicals
A simple cardboard or plastic boat is propelled across the surface of water when the surface tension is disrupted by adding detergent. Once youngsters see this in action, explain about the properties of water that make it possilbe:...
Curated OER
Surface Tension
Students examine the concept of surface tension. In this surface tension lesson students complete several experiments to allow them to better understand surface tension.
Curated OER
Pepper Scatter
Young scholars discover the forces that affect the surface tension of water. In this surface tension lesson plan, students use pepper, soap, and liquid detergent to discover the forces.

Surface Water and Groundwater
Students examine distribution of water and minerals. In this surface and groundwater lesson, students conduct an experiment with fresh and salt water making hypothesis and drawing conclusions about minerals.
Curated OER
Liquids and Gases
In this liquids and gases learning exercise, students will review the basic characteristics of water including surface tension and evaporation. This learning exercise has 1 fill in the blank and 6 short answer questions.
Curated OER
How Many Drops?
Seventh graders hypothesize about the number of drops of liquid that can be placed on a penny before it spills over. They examine both the concept of devising a hypothesis and the idea of surface tension. They determine the difference...
