The "Laser Days in the Classroom" Activity Kit is sponsored by Lockheed Martin and LaserFest. It includes a series of easy-to-demonstrate laser-related educational activities that are targeted to middle-school students. The demonstrations illustrate how regular light differs from laser light; how to use a laser to transmit sound; and how to measure a hair's width with a laser. Other classroom materials include posters, stickers, comic books, and playing cards.
