Light pollution (LP) is one form of environmental pollution less known than most others. It affects the visibility of the night sky, but also alters the balance of the ecosystem and affects human health, since it breaches the biological clocks that are coordinated with periods of light and darkness. To be alert on this subject, learn to recognize the problem, warn others of the consequences, and find solutions, are objectives of the present work.
The LP as subject of study can be also a good point to teach and learn about the uses of light in general, including the problem to rich the starry night from the schoolyard.
The Network for Astronomy School Education (NASE), proposes a set of simple, non expensive and funny activities, especially designed no only to understand the three types of light pollution: glow, intrusion and glare, but also to explain the problems associated to the over- consumption, to show why the public light produces strong and bad effects on the astronomical observation, including the radio region of the electromagnetic spectrum, and affects the human health. NASE workshop on this subject is devoted to the Natural Sciences teachers and professors and for this reason the activity cross over all the secondary school level spaces.
