An instructive lesson provides the basics on how to perform rotations on the coordinate plane. The handout also covers rotating about a point other than the origin and how to perform a series of transformations. 

Young geologists piece together the puzzle of plate tectonics in an earth science lesson. Given a physical map of the world, they search for land formations that indicate the location of different types of plate boundaries.

Here's a resource ideal for independent learners who need extra reinforcement or would like to work ahead. These textbook chapters and practice problems cover many basic physics concepts, starting with potential and kinetic energy and...

Magnets don't grow in fields, but magnetic fields are important to understand. The lesson covers the effect electricity has on magnetic fields. Scholars use a compass, magnets, and electrical wire to test magnetic fields and energy...

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Science rocks! Explore three types of rocks and the rock cycle with an igneous rocks experiment. Pupils discuss textures, composition, and learn how melts are formed from the Earth's crust. They weigh materials using a scientific scale...

An exhaustive set of "lecture notes" on various topics in thermal physics (including thermal expansion). Explanations are well done and more interesting than most. Includes both a mathematical and conceptual treatment of topics. Humor,...

Provides a long list of physics formulas for easy reference.

Find out about the essential role energy plays in cell function and in sustaining life. Trace energy transformations as they pass from one living thing to another.

Explains what protoliths, i.e., parent rocks, are and gives examples of protoliths and the metamorphic rocks they transform into. Each example is accompanied by photographs.

This site is from the Physics Department at Georgia State University. The reliance upon the law of conservation of energy as an approach to problem-solving is presented and encouraged. It is modeled through a problem involving a...

A lengthy set of lecture notes on the topics of thermal expansion and heat absorption. The concept of specific heat capacity is explained and numerical examples are discussed. Heats of transformation (fusion, vaporization) are explained...

A very comprehensive site organized well with many topics dealing with AC circuits.

The first telegraphs are constructed and Michael Faraday produces much of his brilliant and enduring research into electricity and magnetism, inventing the first primitive transformer and generator.

Albert Einstein publishes his special theory of relativity and his theory on the quantum nature of light, which he identified as both a particle and a wave. With ever new appliances, electricity begins to transform everyday life.

Paul Adrien Maurice Dirac was an outstanding twentieth century theoretical physicist whose work was fundamental to the development of quantum mechanics and quantum electrodynamics. He was awarded the Nobel Prize for Physics jointly with...

A university-level discussion of what inductance land resistance does to electricity travelling long distances.

Information about the element, Nitrogen, atomic number 14. Covers common chemical transformations, its physical properties, atomic properties, how abundant it is on the Earth, and details about health-related regulations. Also discusses...

Official Nobel biography of Chen Ning Yang. Emphases on where and when, and on his scientific publications. Little description of his actual scientific work here.

This site has links to tables of mathematical formulas. To view them, the student must download the formulas in pdf format.
