Below are sample questions representative of the exercises included on this worksheet and related 9.149 Big Bang Evidence skill assessments:

Problem 1Difficulty: Mastery

Which final synthesis best matches the grade 9 Big Bang Evidence skill?

ARedshift, CMB, and abundance are useful only if they all come from the same object.

BGalaxy redshifts show expansion, the CMB shows cooled early radiation, and hydrogen-helium abundance shows early light-element formation.

CGalaxy spectra show no motion, the CMB shows a nearby lamp, and hydrogen-helium abundance shows Earth is the universe's center.

DGalaxy redshifts show plate tectonics, the CMB shows ocean tides, and helium abundance shows weathering.

Solution & Explanation:This synthesis correctly connects each major evidence type to the Big Bang model: expansion, cooled radiation, and early light elements.

Problem 2Difficulty: Mastery

A new data table for distant galaxies shows no relationship between distance and redshift after errors are checked. How would this affect a Big Bang evidence argument?

AIt would have no effect because evidence never changes models.

BIt would weaken the redshift-distance part of the argument and require scientists to re-evaluate the model or data.

CIt would strengthen expansion evidence because no trend is always better.

DIt would prove the CMB and abundance data cannot be measured.

Solution & Explanation:Scientific models are tested against evidence. If reliable data removed the redshift-distance trend, that part of the Big Bang evidence argument would be weakened.

Problem 3Difficulty: Mastery

A visual compares a rest spectrum and a galaxy spectrum. The galaxy row has the same absorption-line pattern shifted to the right on a wavelength scale. Which statement is best?

AThe visual gives no information about wavelengths.

BThe galaxy has no identifiable elements because the line pattern matches.

CThe galaxy light is blueshifted because the lines moved toward longer wavelengths.

DThe galaxy light is redshifted because the matching lines moved toward longer wavelengths.

Solution & Explanation:On a wavelength scale that increases to the right, a rightward shift means longer wavelengths. Matching lines shifted longer are redshift evidence.
