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...

Make your own crystals. Learners can use borax, water, food coloring, and a string to make a colorful crystal. This is a great way to explore chemical reactions, crystal formation, or evaporation.

Steve Spangler plays a sneaky trick on Mark by giving him a rubber ball that doesn't bounce! Video viewers learn that different types of rubber have different properties. Show this in your physical science unit when teaching the...

Have your class explore how a hot air balloon works. Through a simple demonstration, learners can see the process up close, and discuss why this occurs. They can then perform related experiments on their own.

Using a step-by-step explanation of the process, this film shows how to use a wooden skewer to pierce a balloon without popping it. Your learners will love this demonstration and they will learn that polymer molecules can stretch and...

Wave properties are fully explained in this easy to follow highly comprehensive video. Matt describes the differences and provides concrete examples of a pules, periodic wave, transverse wave, and longitudinal waves.

Hawaii Preparatory Students, Julia and Rachel, teach viewers about topographic maps. They use great visuals and clear narration to help explain topography.

Now this is a very good demonstration of the Doppler Effect and how it works. A police car with its siren blazing is filmed as it travels closer and then farther away. The effect is explained through text and an illustration. Good video.
