In March the Explorers investigated the relationship between light and color—and found that you can not only split white light into all of the colors of the rainbow, you can also turn the rainbow back into white. Well, sort of, anyway.
Having made our space age color wheels (from such high-tech materials as posterboard, construction paper, scissors, and glue) during our previous session, it was now time to put the finishing touches on them and get them to spin.
In February 2009 the Explorers spent a session investigating the nature of light. They learned that white light is actually anything but white, and that nearly every beam of light has a secret rainbow hiding inside it.
