Blue Sky
Use a container full of water as a prism and show that as light is bent, the individual colors from different wavelengths become visible. This explains why the sky appears to be blue midday, and why as the sun nears the horizon, it looks...

Measuring Star Temperatures
In this measuring star temperatures, students find the temperature of a star using Planck's curve and the Wein Displacement law. Students also find the peak wavelengths for given stars using Planck's curve.

Stargazers
Young scholars discuss the light spectrum and light waves as well as how the properties of light and color have contributed to important discoveries about properties of the universe. They research the term redshift and the redshift...

Color, Computers, and Math
Students visit a web page that gives a brief introduction to two color models and experiment with mixing different color intensities to create different colors. They visit links that give more detailed information on color.
