Description:

In this lesson, students will be introduced to how the Doppler effect changes our perception of wavelengths of sound (pitch) and light (color). Students will model how astronomers use the line spectra of stars to identify elements in the stars and the speeds of galaxies in the universe. Requires some special equipment for spectral analysis and a darkened room for viewing spectra. Suggestions are included for introducing the Doppler Effect for students unfamiliar with this concept. This activity is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1929 Cosmic Times Poster.
