Light: The Physics of Art and Visual Perception
A diffracting grating shows the colors within light like a prism. The tiny slits that make up the grating bend entering light into different directions according to their wavelength, which shows the different colors.

In this activity you can look at the spectrum of light from a candle. Make sure to have adult supervision while working with flames. Diffracting gratings can be purchased cheaply online. Also, you can use your grating to investigate light produced by other light sources in your house.
