Wear-Away and Wandering Water

Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule. 

Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a lesson that stresses the importance of controlling all variables. The second activity allows...

When you have a cold drink and you notice the water forming on the outside, it is literally pulling the water from the surrounding air to form the condensation. After watching a demonstration of condensation forming on a glass,...

A drop of dew holds a sphere shape even when sitting on a seat thanks to the surface tension of water. Learners observe the phenomena of surface tension in water. Through demonstrations, hands-on activities, and discussions they explore...

How does food coloring work? Classes watch a demonstration showing liquids dissolving in liquids. In groups, they then explore the ability of other liquids to dissolve in water (alcohol, mineral oil, and corn syrup) by setting up and...

Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...

A water strider is a bug that taps into the attraction between the positive and negative ends of water, allowing the bug to walk on water. Learners view short videos showing polar characteristics of water. Pairs then discuss what polar...

Discuss the availability of clean, plentiful water and the causes of water pollution. In groups, sixth graders discuss problem-solving methods for keeping water clean. They explore the function of water treatment plants and perform...

Here is an essential lesson for an essential molecule! Immerse seventh graders into a comprehensive two-week journey through one of Earth's most important cycles, the water cycle. Dive into activities that illustrate the movement of...

Elementary kids read and color the story of Willy Wetsworth, a drop of water, as he describes the journey that he and his friends take to provide fresh water to houses. He tells his story to Martha Merriweather, a little girl, and...
