Kids learned the basics of visible and invisible light during a presentation from the Challenger Learning Center of Alaska on Monday, Jan. 16, 2017 at the Soldotna Public Library in Soldotna, Alaska. There wasn’t much sunlight, but the kids attending the event heard about the electromagnetic spectrum and learned how to use a spectrometer to see the types of light in the world around them. Summer Lazenby, the director of educational operations at the Challenger Learning Center, brought filters and spectrometers for the kids to see firsthand how light moves and is split into its different components of color.
