Solar System

We're going to watch a video about the Solar System. Before we do, choose any one of the following "what do you know" questions and tell me a little bit about what you know in the space below...

1. What do you know about the planets in our solar system?

2. What is an example of an orbit?

3. Why do you think Earth orbits the Sun?

4. How do you think scientists explore our solar system

5. How might you describe the Milky Way galaxy?

6. What objects other than planets do you think exist in our solar system?

Okay, my superstars, depending on how you are feeling today, answer ONE of the following exit questions. Level 1 is the easiest and level 3 is the hardest. This is graded, so answer carefully :)

Level 1 -- What force holds the solar system together?

Level 2 -- Name the 8 planets in order starting from the closest planet to the sun.

Level 3 -- Explain why Pluto is no longer a planet.
