Stellar Fingerprints: the Spectra of Stars

Young scientists observe the spectra of elements and compare that to the Doppler effect. Hook scholars from the beginning all the way to the extension activities in this 5E-format lesson. 

In this spectral composition of stars activity, students use data collected by a spectroscope to compare the stellar spectra to a standard for 5 stars. Students compare the spectral lines to the temperatures of the stars.

Young scholars investigate white light. In this science instructional activity, students participate in a variety of experiments in which they study light. Young scholars use spectroscopes to view the components of light.
