The Explorers spent a session in October 2012 investigating invisible light. Just because we can’t see it doesn’t mean it can’t affect us—and with some cleverness we can force the invisible to reveal itself. Indirectly, at least!
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.
