Experiment with water drops to see how molecules stick to themselves! Delicate Water Striders take advantage of surface tension.
Introduce students to a characteristic called cohesion. This is when water molecules stick to each other. Invite students to experiment with water molecules to personally observe what happens.
Students cover their work area with recycled newspaper. Instruct them to fill a cup of water to the top. With a plastic dropper, add a few drops of water. Students observe how the water bulges over the top without spilling! Surface tension holds those additional drops. Keep adding drops until the tension breaks and water spills over.
Invite students to compare how water tension reacts on different surfaces. Thickly color a small area of paper with Crayola Twistables® or Construction Paper Crayons. Pile up water drops on the colored area and also on the plain paper. Which holds more drops before the surface tension breaks? Ask students to explain what they observe.
Insects called Water Striders use the surface tension of water to their advantage. They hunt prey by skimming the surface of still water. Challenge students to find a picture of a Water Strider. Look at how its delicate feet pads rest on top of the water. Can you see how the water’s "skin" actually sinks under the insect’s light weight? Students draw a Water Strider to show how it stands on the water’s surface.
