Properties of Fresh and Sea Water

Investigate how temperature affects the density of water and stratification that occurs in bodies of water when temperatures vary. Water of differing temperatures is given different colors to see the layers that form. The activity is...

As amazing as James Bond is, the surface tension of water does not allow him to walk on it! In this series of little lab activities, physical scientists play with the properties of water due to the hydrogen bonds and resulting polarity....

A micro-unit on the phase changes of water includes three laboratory activities. Junior scientists compare the densities of ice and water, and then they do the same for cold and warm water. They examine freezing and boiling temperatures....

During a unit on density, pupils ponder whether or not temperature affects this property. By carefully inserting blue cold water and yellow hot water into a room-temperature sample, they will see the answer. Make sure to have done the...

Water is powerful! Because it expands as it freezes, if it does so in a closed system, tremendous pressure can be created. All it takes is a little break to cause the system to explode! It's unlikely that you would submerge a pipe full...

Being essential for life is only one of water's many amazing properties! Why is water so versatile? Biology scholars discover the myriad of uses for water and the properties that make them possible. Content includes density, surface...

Why do bricks make terrible windows? Learn about how the different properties of matter, including transparency, reflectivity, and freezing, boiling, and melting points can help you observe what they are, as well as indicate their...

Challenge your sixth graders with this instructional activity about the freezing and boiling points of water. In these activities learners graph temperature data, read and analyze information, and identify the freezing and boiling points...

Students explore the properties of water. In this cross curriculum art and physical science lesson, students experiment with a variety of materials to demonstrate the cohesive forces and adhesion of water. Students create a water color...
