Colm Kelleher describes the physics behind colors- why the colors we see are related to the period of motion and the frequency of waves. [3:09]

NASA provides a nice blending of the achievements of three scientists, Oersted, Ampere, and Maxwell. This done by NASA-sponsored International Solar-Terrestrial Physics group. Lots of pictures, diagrams, and scientific explanation. Good...

A series of thought-intensive, multichoice questions concerning pendulums and provided for by the University of Maryland. A downloadable software program on pendulums is also included.

This tutorial investigates the motion of a mass on a spring and how a variety of quantities change over the course of time. Such quantities will include forces, position, velocity and energy - both kinetic and potential energy. Take the...

Extend students' learning of fundamental physics concepts (reflection, refraction and transmission of energy) through a real-world application.

This tutorial investigates pendulum motion and how a variety of quantities change over the course of time. Such quantities will include forces, position, velocity and energy - both kinetic and potential energy. Take the interactive...

Take a special trip to the Atlanta Symphony Orchestra with GPB Education! This interactive virtual exploration offers students a behind-the-scenes experience as they learn about the science of sound and the preparation it takes to put on...

This is a five-question quiz related to the passage "The Effects of Ear Canal Acoustics on Hearing Ability."

This resource provides a concise overview of the speed of light and the Ole Roemer, the first man to measure it.

[Free Registration/Login Required] An informational text about electromagnetic radiation and the effects it creates. A question sheet is available to help students build skills in reading comprehension.

These labs provide examples of using very open-ended questions to guide learners in exploring a simulation and designing their own experiments. These labs can lead to a high level of quantitative thinking about data analysis.

[Free Registration/Login Required] An descriptive text about the sounds a person would hear at a baseball game. A question sheet is available to help students build skills in reading comprehension.

A good explanation of basic quantum theory.

This lesson will describe how the doppler effect is created by moving sound waves. It is 2 of 4 in the series titled "Doppler Effect."

This lesson will describe how the doppler effect is created by moving sound waves. It is 1 of 4 in the series titled "Doppler Effect."

The universe produces a broad range of light, only a fraction of which is visible to our eyes. Gamma rays are nonvisible light, which also includes x-rays, ultraviolet light, infrared radiation, and radio waves.

Illustrated diagrams and interactive practice problems show constructive and destructive interference occurring at sound beats.

Students investigate an example of interference that provides further evidence in support of the wavelike behavior of light.

Through illustrated practice problems and video clips, students learn about polarization of light.

Through illustrated example problems, and some interactive practice, students learn about color addition and color perception.

Students will focus on the interaction of sunlight with atmospheric particles to produce blue skies and red sunsets.

Students learn how the eye responds to visible light, and how that function ultimately allows us to see.

[Free Registration/Login may be required to access all resource tools.] Students investigate the fundamentals of light including its source, how it is defined for measurements, how we perceive color, and the situations that make an...
