These slides summarize the properties that define materials. The categories of physical and chemical changes that are used to describe substances are listed and students will find the examples of those changes useful. You could set the...

This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse...

The tension of the 236 strings in a grand piano exert a combined force of 20 tons on the cast iron frame. The presentation includes topics such as work, forms of energy, conservation of energy, gravitational and elastic potential energy,...

Teens often display potential energy in class and kinetic in the hallways. This third presentation covers the six types of energy, each in potential and kinetic form. It also covers the Law of Conservation of Energy and Einstein's...

A fun slide show which illustrates different size bugs hitting car windshields. Your junior highers should be amused while they learn the relationships between mass, velocity, and force of an impact. Scientific terminology is used, but...

Why did lightning shock the man? Because it didn't know how to conduct itself. Presentation covers electric charges, insulators, conductors, electroscopes, lightning, generators, grounding, static electricity, and more. Presentation...

Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...

Be impulsive with your high school physics class. Emerging physicists review the slide presentation and learn about impulse, momentum, collisions, and how each variable may be affected. They complete practice problems and conclude with a...

Moving from its definition to how it moves and its different types, scholars see different examples and then move into its application and use in everyday lives, in an energy-based presentation.   

This lesson explains the law of conservation of mass within chemical reactions. It is 3 of 4 in the series titled "Conservation of Mass."
