In this science fair project, use an infrared thermometer to measure the temperature of differently colored paper exposed to sunlight, and calculate energy emission using the Stefan-Boltzmann equation. Find discussion questions, a list...

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.

Students test whether the color of a material affects how much heat it absorbs. Students will place an ice cube in a box made of colored paper (one box per color; white, yellow, red and black), which they will place in the sun. The...
