Life is only a reflection of what we allow ourselves to see. The lesson includes three experiments on light reflection, light refraction, projection, lenses, and optical systems. Each experiment builds off the ones before and...

Did you see that or did I imagine it? Optical illusions are often created with mirrors and lenses, and here is a presentation that covers many different types of mirrors and lenses and how they work. Flat, concave, and convex mirrors, as...

Apply the concept of similar triangles to design a space in a room. Scholars use similar triangles to determine how a spotlight reflects from a mirror. After drawing the path of the spotlight, individuals find the smallest possible width...

Step aside, fancy glasses... it's time to create a solar eclipse viewing camera of your own using nothing more than a milk carton. 

Students participate in this skill-building activity where they explore how the location of an object in front of a curved mirror affects the characteristics of the projected image.

You've probably noticed the colorful patterns "reflecting" from the shiny surface of a CD disk. What you are seeing is actually diffraction of white light, and the rainbows of color are diffraction patterns. In this project you'll learn...

Several short descriptions of demonstrations which illustrate principles of geometric optics (many of which focus upon refraction).

This website, from the University of Edinburgh, provides a lengthy glossary of computer graphics terms written by Olin Lathrop, author of "The Way Computer Graphics Work". This site provides simple definitions of basic terms; no graphics...

Exploratorium's snacks aren't edible, but they are good! Use your science skills to discover gravity, learn about biology, do fun experiments.
