In honor of our Young Reader's League selection for 2016, Circus Mirandus by Cassie Beasley, our science program for tweens for November was about light like the Light Bender character from the novel. We learned about our sun, turned CDs and poster tubes into spectroscopes and analyzed various light bulbs for their absorption spectra, played with color filters and wrote secret messages, and played with color LED lights and made shadows of various colors. I had one more activity planned about demonstrating the Inverse Square law of light but we ran out of time. I got most of my activities from a wonderful website: exploratorium.edu/snacks.
