Resource	Grade Level	Media Type
Airplanes: Designing for Stealth Explore this NOVA interactive activity to see how engineers have modified a military plane's sound, shape, and heat emissions to minimize detection.	6-12	Flash Interactive
Amplitude This interactive activity adapted from the University of Utah's ASPIRE Lab shows how a pendulum's amplitude changes as you set it swinging from different distances from its axis, and how the amplitude of a sound wave changes as you adjust the volume.	6-12	Flash Interactive
Astronomical Images in Different Wavelengths Visible light is just one portion of the electromagnetic spectrum that a telescope may detect. This collection of images produced for Teachers' Domain features radio wave, infrared, visible light, and X-ray images of distant stars and galaxies as well as images of the telescopes designed to detect the various wavelengths of radiation.	6-12	Flash Interactive
The Electromagnetic Spectrum: FRONTLINE This video segment adapted from FRONTLINE introduces the electromagnetic spectrum and explains how the various types of electromagnetic waves are distinguished by the amount of energy each wave carries.	6-12	QuickTime Video
The Electromagnetic Spectrum: NASA From radio waves to gamma rays, this video segment from NASA introduces the seven categories of the electromagnetic spectrum and how each type of radiation is part of our everyday lives.	3-12	QuickTime Video
Frequency In this interactive activity adapted from the University of Utah's ASPIRE Lab, investigate frequency in terms of trampoline jumps, pendulum swings, and electromagnetic waves.	6-12	Flash Interactive
How Is a Radio Wave Emitted? This illustrated essay from A Science Odyssey Web site explains the science behind radio waves, including the role of electrons and electromagnetic fields.	6-12	HTML Interactive
Imaging with Radar This interactive activity from NOVA features synthetic aperture radar (SAR), which uses radio waves to create high-quality images. Examine SAR images of Washington, D.C., and learn about this technology's unique advantages.	6-12	Flash Interactive
Inverse Square Law This animation from KET's distance learning physics course demonstrates the mathematical formula for a scientific law as it applies to light.	6-12	HTML Interactive
Making Waves with the Electromagnetic Spectrum Students explore various types of electromagnetc waves to better understand the electromagnetic spectrum.	9-12	Lesson Plan
Pulsars: Jocelyn Bell In this video segment adapted from the NOVA, we meet Jocelyn Bell, a graduate student responsible for the discovery of pulsars.	6-12	QuickTime Video
Pulsars: Little Green Men The story behind Jocelyn Bell's role in the discovery of pulsars is told in this colorful, comic-book-style resource from A Science Odyssey Web site.	6-12	HTML Document
Radio Transmission This interactive activity from A Science Odyssey tracks the journey of a sound wave from the moment a musician sings into a microphone until his voice reaches the vibrating speakers of an AM Radio.	6-12	Shockwave Interactive
Radio Waves & Electromagnetic Fields In this interactive simulation adapted from the University of Colorado's Physics Education Technology project, explore how a radio transmitter broadcasts electromagnetic radiation.	6-12	Java Web Start Interactive
Radio Waves: FM vs. AM This brief essay from A Science Odyssey Web site describes the difference between FM and AM radio waves.	6-12	HTML Interactive
