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.

This video from NASA describes the GLAST satellite, which is equipped with a gamma-ray telescope, and shares some background about the kinds of extreme universal phenomena indicated by the presence of gamma rays.

This video segment from Swift: Eyes through Time introduces and explains theories of the origin of gamma-ray bursts.

Build your own miniature "greenhouse" out of a plastic container and plastic wrap, and fill it with different things such as dirt and sand to observe the effect this has on temperature. Monitor the temperature using temperature probes and digitally plot the data on the graphs provided in the activity.

Make your own miniature greenhouse and measure the light levels at different "times of day"--modeled by changing the angle of a lamp on the greenhouse--using a light sensor. Next, investigate the temperature in your greenhouse with and without a cover. Learn how a greenhouse works and how you can regulate the temperature in your model greenhouse.

In this video segment adapted from Shedding Light on Science, observe demonstrations of the fundamental idea that light travels in straight lines.

In this lesson students will use UV beads to observe and draw energy. Students will describe how light can be produced, reflected, refracted, and separated into visible light of various colors.

Students will learn the difference between an insulator and a conductor and why conductors help to close electricalcircuits. This is important content to better understand how energy and particularly electrical energy works.

This animation from KET's distance learning physics course demonstrates the mathematical formula for a scientific law as it applies to light.

In this video from the Encyclopedia of Physics Demonstrations, observe how a laser beam is trapped in a water jet because the light reflects against the surface of the water.

This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they are introduced to Einstein's life and work with four engaging and kid-friendly areas. Equation Invasion, a look at the world's most famous equation about the relationship between energy and mass. Web Master, the scientists whose ideas and discoveries shaped Einstein's career. Light the Way, an introduction to "the fastest thing in the universe" and the waves it travels in. Everyday Einstein: LASERS, a comic strip that illustrates how Einstein's work led to the development of lasers.

Students are introduced to the correct technical vocabulary for lighting, which is different than layperson's terms. They learn about lamp (light bulb) technology and how to identify the various types of lighting in their spaces. They are also introduced to lighting controls as a means for saving energy- reducing costs, human energy consumption, and greenhouse gas emissions on the environment. Using an accompanying worksheet, students embark on a guided audit in which they survey the lighting in their classroom and identify the potential savings from using controls.

This video segment adapted from Shedding Light on Science describes how astronomical distances can be measured in units of light-years, and how the finite speed of light allows astronomers to study how the universe looked long ago.

This video segment adapted from Shedding Light on Science demonstrates the law of reflection by showing how light energy is reflected off both smooth and rough surfaces at predictable angles.

This video segment of Swift: Eyes through Time provides concrete examples to explain the concept that distance in space equals distance in time.

Learn about an important physics experiment that uses an invention that manipulates light in this interactive activity adapted from NASA.

This video segment adapted from Shedding Light on Science illustrates how light changes speed, and thus direction, in a process known as refraction.

Solar energy in the form of light is available to organisms on Earth in abundance. Natural systems and other organisms have structures that function in ways to manage the interaction with and use of this energy. Using these natural examples, humans have (in the past) and continue to design and construct homes which manage solar energy in passive and active ways to reduce the need for energy from other sources. In this storyline, students will explore passive and active solar energy management through examples in the natural world. Students will use knowledge gained to design a building that maximizes the free and abundant energy gifts of the sun.

No other chemical process is as crucial for the existence of life as photosynthesis. Photosynthesis is the process of converting light energy to chemical energy. This Mini Lecture deals with the basic processes taking place in the chloroplasts of plants with lecture snippets of John Walker, Hartmut Michel, and Steven Chu.

The People's Physics Book v3 is intended to be used as one small part of a multifaceted strategy to teach physics conceptually and mathematically
