How does one exactly illustrate the principle of chaos? Well, fortunately for budding physicists and other interested parties, a very nice animation demonstrating chaos (and other such processes and phenomena) are made...

Richard Feynman was one of the great communicators and scholars within the field of physics, and his very accessible lectures remain the stuff of legend. While Professor Feynman is no longer with us, physics teachers can...

This site explains why three percent is a fundamental limit of X-ray detectors that use the conventional method of conversion to electric charges, and if a higher spectral resolution is required astronomers have to...

At this site students are reminded that the study of atoms and their characteristics overlap several different sciences and that chemists, physicists, and astronomers all must understand the microscopic scale at which...

This resource describes special properties of light that can help us to understand objects that are millions and billions of light years away. Students explore some of these properties and how they can use them to...

This activity describes the basic structure of an atom using an edible model and explains the quantum mechanical nature of the atom. For example, originally, each electron orbital was pictured as having a specific...

This activity introduces two different representations of spectra: the photographic representation, such as the rainbow, and the graphical representation used more often by astronomers. A rainbow is often given as an...

Visit this Web site from the National Teacher Training Institute (NTTI) for a set of engaging lesson plans for middle and high school students. The latest life science offerings address DNA and RNA, pika camouflage,...

A collection of some 25,000 historical photographs, slides, lithographs, engravings, and other visual materials, focusing on American physicists and astronomers of the twentieth century, but including many scientists in...
