What educators are saying
This resource helped students see that spectra can be used to tell what elements are present in stars, and the last two problems showed what the shift in light frequencies due to motion looks like. They found it easy to do but it was a good learning experience.
Description
Contains Printable Reference Spectra for 6 commonly found elements- along with ten mystery star spectra. Students are asked to use references to identify the elemental composition of the mystery samples.
Mystery Stars contain 1-3 elements. Also, there is one blue-shifted and one red-shifted spectra to introduce students to the idea.
Suggested to have students use highlighters to keep track of each element they find.

NGSSHS-ESS1-3
Communicate scientific ideas about the way stars, over their life cycle, produce elements. Emphasis is on the way nucleosynthesis, and therefore the different elements created, varies as a function of the mass of a star and the stage of its lifetime. Details of the many different nucleosynthesis pathways for stars of differing masses are not assessed.
NGSSHS-ESS1-2
Construct an explanation of the Big Bang theory based on astronomical evidence of light spectra, motion of distant galaxies, and composition of matter in the universe. Emphasis is on the astronomical evidence of the red shift of light from galaxies as an indication that the universe is currently expanding, the cosmic microwave background as the remnant radiation from the Big Bang, and the observed composition of ordinary matter of the universe, primarily found in stars and interstellar gases (from the spectra of electromagnetic radiation from stars), which matches that predicted by the Big Bang theory (3/4 hydrogen and 1/4 helium).
