1. I can define and use unit vocabulary terms.
Complete the puzzle below. Created with Discovery Channel School's PuzzleMaker.
_________________________________________________ has reviewed for the size and scale test.
_____5. compare the size of the Solar System to the size of the Milky Way galaxy; the size of the Milky Way
galaxy to the size of the known universe.
Objective – Understand the scale of size, distance between objects, and movement of objects in the universe
Across
4. A group of about 100 to 400 billion stars formed in a disk-shaped spiral that contains our solar system.
7. Spherical balls of rock and/or gas that orbit a star that have enough of their own gravity to become round.
8. How far one object is from another.
9. Huge balls of gas held together by gravity.
10. An instrument used to view distant objects.
12. About 186,000 miles per second (300,000 kilometers per second)
Down
1. A group of hundreds of billions of stars held together by gravity.
2. Used to measure relative distances in space; in light years
3. The distance light travels in one year.
4. Amount of matter in an object.
5. The force (-push or pull on an object-) that causes objects to fall to the ground and also the force that keeps the
Moon circling Earth instead of flying off into space in a straight line
6. Everything that exists; all matter and energy; also includes all of space and time.
11. A push or pull on an object.
12. A star.
2. I can use the speed of light as a measuring standard to describe the distances to objects in the universe.

Speed of Light – __________________________________________ mps (miles per second)

Speed of Light – __________________________________________ kps (kilometers per second)

Objective – Understand the scale of size, distance between objects, and movement of objects in the universe
Use the diagram to answer the following questions.
a. Which group of planets are closest together, the inner rocky planets or the outer gas giants?
__________________________________________________________________________________________
b. Which group of planets are farthest apart, the inner rocky planets or the outer gas giants?

What if the largest planet was closest to the Sun and the smallest was farthest? What would the Solar System look like? In the table
below, order the planets from largest to smallest – largest closest to the Sun, smallest farthest from the Sun.
