Students begin by studying the electromagnetic spectrum and come to understand how astronomers study the sky by detecting invisible light. After learning the types and properties of visible and invisible light, students are ready to investigate the massive and violent waves of radiation in space called gamma-ray bursts.

[WEB SITE] Ripple Tank Simulation : For Light and sound :  It demonstrates waves in two dimensions, including such wave phenomena as interference, diffraction (single slit, double slit, etc.), refraction, resonance, phased arrays, and the Doppler effect.  To get started with the applet, just go through the items in the Example menu in the upper right. You can also draw on the screen with the mouse.

KIT: The outside detector [realia] : ultraviolet detector. - Contains UV Detecting Beads inside of a clear plastic bottle preform. When the detector is shielded from UV radiation, the beads are white. When exposed to UV radiation (between 360 and 300 nm wavelength), the beads turn purple. This detector can change color thousands of times.

KIT:Wave apparatus model-Crank the handle and will generate longitudinal and transverse waves.  ... students will generate transverse and longitudinal waves and describe their differentiating characteristics. They'll immediately see the wave forms and how they propagate. Apparatus can be used to demonstrate sound, light and heat waves; wave forms; and interference and propagation of wave forms.
