Explain: Definition, Examples, Graphics, and Uses (astronomy connection) for each type of spectrum.
Explore: Using absorption spectrums of specific elements and mystery stars, students will identify all the elements they can detect in each star's atmosphere.
Elaborate: Concept reinforcement. Link to video clip. So far we've learned about how atoms can absorb the light of particular colors (absorption spectrum), or when heated up, emit light of those same colors (emission spectrum). But how does it do that? And why is it only certain colors?
Extend: Using a set of Star Spectra and Line Plot Cards, students will match each spectrum with its correct line plot.
