This assessment is aligned to Next Generation Science Standards for high school Earth and Space Science. It assesses one piece of evidence for the Big Bang Theory (HS-ESS1-2): red-shift of galaxies light and its implications for the movement/expansion of galaxies. Because the spectra are in COLOR, access to a color printer (or a projector) is important.
HS-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.
Students should be able to:
- explain how scientists use galaxy spectra to determine the movement of galaxies.
- observe absorption lines to determine the "shift" of the galaxy and its implication for the galaxy's movement
- explain how the red-shift of light from distant galaxies supports the Big Bang Theory
