Glowing in the Dark

In this activity, students will learn about phosphorescence and how certain materials can absorb and store energy from a light source. Students will use critical thinking skills to hypothesize which type of light -- incandescent, ultraviolet, infrared or fluorescent -- will produce the brightest glow from a glow-in-the-dark star. Students will perform an experiment using cameras to observe the intensity of the resulting glow from each type of light source.
