The Physics of Astronomy : Spectroscopy of Stars - Wonders of the Universe

This lesson plan focuses on the following standards.
Construct an explanation of the origin, expansion, and scale of the universe based on astronomical evidence.

● The study of stars' light spectra and brightness is used to identify compositional elements of stars, their movements, and their distances from Earth

Plus HS+Phy.P4U1.6 Analyze and interpret data to quantitatively describe changes in energy within a system and/or energy flows in and out of a system.

HS+E.E2U1.12 Obtain, evaluate, and communicate scientific information about the way stars, throughout their stellar stages, produce elements and energy.
Construct an explanation about the relationships among the frequency, wavelength, and speed of waves traveling in various media, and their applications to modern technology.

● The wavelength and frequency of a wave are related to one another by the speed of travel of the wave, which depends on the type of wave and the medium through which it is passing.
