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...

Here's a presentation that not only covers momentum, impulse, conservation of momentum in both one and two dimensions, angular momentum, torque, and the moment of inertia, but offers many applied guided practice problems as well.

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...

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

An extremely thorough presentation walks new chemists through the basics of matter. There really isn't a unifying theme, however So many topics are covered: forces, elements, atomic structure, chemical properties, compounds, quarks,...

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...

Wow! This comprehensive collection of slides will walk your chemistry class through the foundation of chemical reactions, teach them to balance equations, differentiate types of reactions, and calculate stoichiometry problems. This...

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...

Find out about FDR's vision and the New Deal plan that helped pull America out of the Great Depression. The presentation focuses New Deal programs such as the Works Progress Administration, Agricultural Adjustment Administration, and the...

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...

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...

Balancing equations is a foundational skill for starting chemists. There are a few slides in this PowerPoint with colorful diagrams that help to explain how. Unfortunately, the presentation begins with an unrelated table of contents and...

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."
