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.

Stream Table

In this activity, students will use a stream table to investigate river formations in two different landscape scenarios. Students will compare and contrast how the formation of the river differs if the topography of the land is changed from a flat plain to a terrain with hills and valleys.
