Students learn the basics of the electromagnetic spectrum and how various types of electromagnetic waves are related in terms of wavelength and energy. In addition, they are introduced to the various types of waves that make up the electromagnetic spectrum including, radio waves, ultraviolet waves, visible light and infrared waves. These topics help inform students before they turn to designing solutions to an overarching engineering challenge question.

The electric field lines from a point charge evolve in time as the charge moves. Watch radiation propagate outward at the speed of light as you wiggle the charge. Stop a moving charge to see bremsstrahlung (braking) radiation. Explore the radiation patterns as the charge moves with sinusoidal, circular, or linear motion. You can move the charge any way you like, as long as you don���������t exceed the speed of light.

Students participating in Storm Signals play a critical role in the overall process of the Student Observation Network (S.O.N.). They are able to confirm the predictions of the Sunspotter's Sunspot Suspect, and they will predict magnetic storms around Earth, issuing Space Weather alerts that tell other students to begin monitoring the Magnetosphere for magnetic storms. By collecting and analyzing real-time data from their radio antennas, professional observatories, and NASA satellites, they can carry out the same duties as NASA researchers! The Space Weather alerts issued by the Space Environment Center (SEC) of NOAA (National Oceanographic and Atmospheric Administration) are essential to protect satellites, power grids and astronauts.
In Storm Signals you will learn:
1. How to instruct students in the construction of a simple device to detect radio emissions from the Sun.
2. How to enable students to obtain and interpret radio emissions from ground-based professional observatories.
3. How to enable students to obtain and interpret radio, x-ray and ultraviolet emissions from NASA satellites.
