This is an activity about spectroscopy. Learners will build a spectroscope and use it to observe various types of lights. This activity requires spectroscope kits and diffraction gratings available from the Stanford Solar Center... (View More)

In this activity, learners will build a structure using a shoebox, aluminum foil, paper, rubber bands, glue, tape, and other common materials that will meet the following criteria when tested: 1) protect an ice cube from melting under a hot lamp or... (View More)

This is an activity about wavelength and frequency. Using a 30 to 50 foot rope and two volunteers, learners will observe as one end of the rope is shaken and wavelength patterns are created. They will estimate the wavelength, the distance between... (View More)

This is an activity about seasonal variations in day length. Learners will graph the number of daylight hours in each month in cities around the world and compare results. They will also gain an understanding of the meaning of the term equinox... (View More)
