Like water drops in falling rain, a CD separates white light into all the colors that make it up.

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.
