The Optical Society of America operates this creative site where children can learn all about optics and its applications. Entertaining chameleon characters guide users through many sections of the site, explaining various concepts and suggesting activities. There is a large selection of educational articles about common phenomena, such as holograms, kaleidoscopes, reflection, and refraction. Examples of everyday occurrences of optics are also explored. The Optics/Laser Lab goes to two offsite resources; one requires free registration and the other requires downloading a special plug-in. Lesson plans for teachers are given on the site as well.
