Have you ever wanted to break the speed of light from your backyard? Something seemingly impossible, and technically improbable, looks impressive thanks to the "magic" of science. The brief video explains how photons can travel from your...

Where did our sun come from? Scientists believe that the sun and our solar system was born from a supernova. Part two of this five-part series explains the sun's plasma, magnetic field, sunlight, and something called flux ropes. This is...

This collection of animated slides offers an explanation of the photosynthesis process. It must be homemade as the sounds of dishes clanging, a television commercial, and computer mouse clicks are heard in the background. You will need...

This video segment adapted from Shedding Light on Science illustrates the dispersion of light through a prism and how raindrops refract sunlight to form rainbows. [3:55]

An explanation of the absorption and emission of energy using shell models. [10:30]

Video lesson studies the Calvin Cycle, or the light-independent (dark) reactions of photosynthesis. [13:27]

Video lecture focuses on light-dependent reactions that use photons from the sun and includes the structure of the chloroplast, the photosystems, and how ATP is synthesized. [20:15]

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. [2:58]

A tour of radio waves in the electromagnetic spectrum. [3:38]

Physicists and astronomers have different views of photons, what they are, and how they behave. Watch as three University of Nottingham scientists discuss the nature of photons and why the study of light is important. [8:32]

In the following video Paul Andersen explains how light travels in photons which can be described as both particles and waves. Einstein showed that photons can be described as particles using the photoelectric effect to show that the...

Provides an introduction to light and the electromagnetic spectrum, and how light behaves as both a wave and a particle. [9:36]

Looks at the history of atomic theory and ideas about atomic models that have evolved over time. Covers models put forward by John Dalton, J.J. Thomson, Earnest Rutherford, Niels Bohr, and the work of Schrodinger and Heisenberg. Also...

Revisiting a theory from 1934, scientists are investigating whether it is possible to develop a photon-photon collider which theoretically could convert light into matter. Aired May 23, 2014 [11:50 min]

This video gives an overview of photosynthesis by breaking it down into 2 stages: light-dependent reactions and the Calvin cycle. [4:47]

In this video, David (and surfer Dan) explain how to determine the momentum of a photon.

This lesson discusses the light spectrum and its influence on living things. It is 1 of 3 in the series titled "Radiation and Energy."
