Bbc: Gcse Bitesize: General Properties of Waves
Light travels as waves. Waves can be described by their amplitude, wavelength and frequency. The speed of a wave can be calculated from its frequency and wavelength.
Optical Society
Optical Society of America: Optics for Kids: Mirrors and Images
An experiment to investigate how many images appear as the angle between two hinged mirrors is increased. Accompanied by an explanation of what is happening, questions for students to consider, and a link to an article about reflection.
Khan Academy
Khan Academy: Eye Disease and Contact Lenses
Punctate keratitis is an eye disease that results in abrasions on the epithelial cornea. One of the leading causes of the disease is the overuse of contact lenses. A research team is investigating the optical properties of four new types...

The Physics Classroom: Blue Skies and Red Sunsets
This high school resource shows how the blue of the skies and the red of the sunsets can be explained by the interaction of sunlight with atmospheric particles which causes scattering of light.
Florida State University
Florida State University: Molecular Expressions: Basic Concepts in Optical Microscopy
This site explores the microscope in great detail. Content includes a focus on the microscope's basic functions (including a general diagram), the history of the microscope, each feature of the microscope, differing objectives,...
National Gallery of Art
National Gallery of Art: The Elements of Art: Color
Students will be introduced to color, one of the basic elements of art, through analysis of works of art by Monet, Matisse, and Kandinsky. Class discussion focused on these paintings will help students understand how artists use color to...
University of Chicago
University of Chicago: Reflector and Refractor
From the Yerkes Observatory Virtual Tour web site. Compares and contrasts reflecting and refracting telescopes. A link from the page leads to a second page which explains why most modern research telescopes are reflecting telescopes.
ClassFlow
Class Flow: How We See Things
[Free Registration/Login Required] In this unit children learn that mirrors and shiny surfaces alter the direction in which light travels and that when they see objects light enters the eye. Children contrast reflection and shadow...
PBS
Pbs Learning Media: Earth's Albedo and Global Warming
In this interactive activity adapted from NASA and the U.S. Geological Survey, learn about Earth's albedo (the ratio of reflected vs. incident solar radiation), how pollution alters albedo, and how ice-albedo feedback may accelerate...
