Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

This is a fun mapping activity that will have your class knowing the ins and outs of the battles in the War of 1812. Your young cartographers will not only plot decisive attacks, but will analyze their purpose, goals, and impact on...

What is reflectivity, and what does it have to do with the Earth's climate? As reflectivity is measured by albedo, scientists can gather information on Earth's energy balances that relate to global warming or climate change. Budding...

An in-depth discussion on reflection of light can be found here. Among the topics discussed include are the difference between specular and diffuse reflection, concave and convex mirrors, facets, total internal reflection, and much more....

See how light knocks electrons off a metal target, and recreate the experiment that spawned the field of quantum mechanics. Describe how the results lead to the photon model of light.

Make waves with a dripping faucet, audio speaker, or laser. Add a second source or a pair of slits to create an interference pattern.

Learn about mechanical waves, which transfers energy from one place to another through liquids, gases and solids, with this interactive lesson.

[Free Registration/Login may be required to access all resource tools.] How visible light interacts with matter and classifying matter in terms of light.

[Free Registration/Login Required] In the scenario shown here, the laser cannot shine through the black barrier but can hit all three targets by reflecting off of the floor. Use the red dot to change the angle of the laser generator and...

The Sound and Light interactive investigates these two forms of energy. Students will enjoy exploring how sound and light are created, travel, and can be controlled.

[Free Registration/Login may be required to access all resource tools.] Ways that waves can interact with matter and examples.

[Free Registration/Login Required] Explore how Snell's Law arises out of the principle of least time; understand how light rays change direction at interfaces between materials using this interactive simulation. A PDF worksheet and a...

Learn about the properties of materials in their interactions with light, including whether they are opaque, transparent, or translucent, and which of these produce shadows.

[Free Registration/Login Required] Move the light source to see what happens to the reflected ray as you change the angle of the incident ray.

[Free Registration/Login Required] Learn about the interference and diffraction patterns that result when a wave passes through one or two thin openings using this interactive simulation. A PDF worksheet and a video tutorial are also...

This digital textbook covers core physical science concepts and includes interactive features, real world examples, and videos.
