At this site students are reminded that the study of atoms and their characteristics overlap several different sciences and that chemists, physicists, and astronomers all must understand the microscopic scale at which...
This lesson is based on the concepts of frequency and wavelength, how they relate to each other, and how they correlate with the colors of the visible spectrum. The students will examine these concepts through a hands-on...
This activity demonstrates how white light, such as that from an overhead projector, is broken up into its component colors by a diffraction grating. Students will learn the relationships between light's wavelength,...
This collection of activities and information teaches students about Gamma ray bursts by having them follow exactly the same procedures used by today's astronomers. Students will review some basic physics concepts about...
This resource will demonstrate the inverse square law to students and will show that this law applies to both the intensity of light and the force of gravity. The relative amount of sunlight received in the vicinity of...
This article provides information on the theory of operation and terminology associated with optical light curtains. The site is produced by Omron, and provide crucial safety tips about the process of using this...
The WorldWide Telescope (WWT) is a Web 2.0 visualization software environment that enables your computer to function as a virtual telescope. This brings together imagery from the best ground and space-based telescopes in...
Hands-On Astrophysics is a flexible set of hands-on educational materials, activities, and investigations. These materials are based on the AAVSO's unique electronic database of variable star measurements. By carrying...
This online encyclopedia explains the terms and principles of laser physics and technology. It also includes content from other topics such as general optics and optoelectronics, nonlinear optics, quantum optics, fiber...
This site, provided by the Center for Science Education at the University of California Berkeley, contains an activity to experiment with shadows and light sources and to understand the relationship between the angle of...
