8.8(A) describe components of the universe, including stars, nebulae, and
galaxies, and use models such as the Hertsprung-Russell diagram for
classification
8.8(B) recognize that the Sun is a medium-sized star near the edge of a
disc-shaped galaxy of stars and that the Sun is many thousands of times
closer to Earth than any other star
8.8(C) explore how different wavelengths of the electromagnetic spectrum
such as light and radio waves are used to gain information about distances
and properties of components in the universe
8.8(D) model and describe how light years are used to measure distances
and sizes in the universe
8.8(E) research how scientific data are used as evidence to develop
scientific theories to describe the origin of the universe

revolves around the Earth.
3. Starting with the moon closest to the Sun, order the moons using numbers
1-8. Write the number in the gray box next to the moon.
4. Imagine you are standing on Earth at the X positions. Shade the moons to
show what you would see from your view on Earth.
5. Next to each moon, write the name of the lunar phase.
