Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains multiple...

The optimist sees the glass half full. The pessimist sees the glass half empty. The chemist sees the glass completely full, half with liquid and half with air. The viewers of this video will see the many ways liquids, like the one the...

How can you effectively provide detailed concepts of water properties to your high school class in a way they find exciting and challenging at the same time? By letting them play, of course! Through a variety of experiments, pupils...

Water is common? Not really! Learn how the polarity of the water molecule gives it tremendous properties that make is quite unique in the universe. Learners will understand surface tension, adhesion, and cohesion, as well as why these...

Get close up and personal with a drop of water to discover how the polarity of its molecules affect its behavior. Elementary hydrologists split and combine water droplets, and also compare them to drops of oil. Much neater than placing a...

Five fabulous procedures introduce physics or chemistry classes to special properties of matter. They discover adhesion and cohesion, solubility, melting and boiling points, and viscosity through hands-on experiences. Tests are...

How attractive is your intermolecular forces lesson plan? Draw your class in with an activity that includes research, presentation, and demonstrations. Chemistry scholars work together to create claims about the each intermolecular...

Let knowledge of chemistry flow like water. Future scientists conduct two different experiments to investigate the properties of water. They learn about surface tension and cohesion as they see how many drops of water they can place on a...

Not all water is the same! Young scientists investigate and compare properties of hard and soft water. They focus on properties of surface tension, density, and the ability to mix with soap during their experimentation.

Black inks have identifying signatures. Using chromatography, learners decode these signatures. They practice their chromatography skills while exploring the differences between the inks.

What colors exist in the rainbow? Pupils explore primary and secondary colors in one part of the series called Christa's Lost Lessons series by mixing colored water and creating a walking rainbow. They perform an experiment to learn...

How do properties of water change in space? Learners explore the concept of chromatography in the installment of Christa's Lost Lessons series as they learn about capillary action. They compare findings from an in-class experiment or...

Did you know many insects use cohesion or surface tension to walk on water? Using a presentation, scholars learn the more important properties of water. It extends into the concepts of solutions, suspensions, pH, and more.

To tape or to glue? Finally, an answer to a very sticky question. The narrator of a short, entertaining video offers insight into the science of adhesion.

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...

Your plants will survive without you. Scholars create a device that can water plants using a coiled string. Along the way, they learn about adhesion and cohesion of water. The challenge is to keep the plants alive for at least a week.

You won't regret being stuck with this activity. By mixing a variety of household items, pupils create their own glue. They test the tensile strength of their glue and compare it to that of other adhesives.

Use science to help you walk on water! Young scientists explore the properties of liquids including cohesion, adhesion, and surface tension. They use graphs to compare different liquids and make predictions about their molecular attraction.
