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,...

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...

Wow! Colorful and simple, these 160 slides introduce the various forms of energy, along with a relevant image. Some of the images are animations, which help beginning physical scientists to visualize the flow of electrons or energy! This...

Graphic organizers, photos, diagrams, and text bring the world of chemical reactions to life. By viewing this presentation, young chemists learn how to recognize when a chemical reaction has occurred, and how to balance chemical...

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...

In this PowerPoint, students compete in a quiz show game similar to Jeopardy in which they generate questions to match science facts in a number of categories. Science concepts covered include plants, animals, and matter. Due to the vast...

Here's a terrific Jeopardy-style game that's designed for 3rd and 4th grade students of science. The topics include living things, animals, plants, matter, and "hodge-podge." The questions are all age appropriate, and there is an...

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.
