Below are sample questions representative of the exercises included on this worksheet and related 8.106 Structure of the Universe skill assessments:

Problem 1Difficulty: Mastery

Which final summary is most accurate for Grade 8 structure of the universe?

APlanets contain stars, stars contain galaxies, and kilometers cannot measure any distance

BStars can be organized into galaxies; galaxies can be organized into groups and clusters; light-years describe the enormous distances involved

CThe observable universe contains only Earth and the Moon

DLight-years measure how many years a planet has existed

Solution & Explanation:This summary correctly states the organization of stars and galaxies and uses light-years as distance units.

Problem 2Difficulty: Mastery

A diagram labels Earth as the center of the observable universe. Which correction should be added?

AThe diagram is centered on Earth because it shows what we can observe from Earth, not because Earth is proven to be the center of all space

BThe diagram proves all galaxies orbit Earth

CThe diagram means the Milky Way is outside the universe

DThe diagram should label every star as a planet

Solution & Explanation:Observable-universe diagrams are observer-centered because light reaches the observer from all directions. That does not prove a physical center.

Problem 3Difficulty: Mastery

A table uses kilometers for Earth-Moon distance and galaxy diameter, making the galaxy number extremely long. Which improvement is most reasonable?

AUse liters for every distance

BUse kilograms for the galaxy diameter

CUse no units because space distances cannot be measured

DUse light-years for very large star and galaxy distances while keeping smaller solar-system distances in smaller units

Solution & Explanation:Different scales often need different units. Light-years are helpful for large distances to stars and galaxies.
