1. The Sun looks larger on Earth than on Jupiter because .

2. Why do all these moons orbit around Jupiter?

• The pull of gravity from each of the moons holds the others in place around Jupiter.
• Jupiter has the strongest gravitational pull of anything in the Solar System.
• The Sun's gravitational pull is very weak in the part of the solar system where Jupiter is found.
• Jupiter has a strong gravitational pull and they are in its gravitational field.

3. Draw a model to show how the movement of Jupiter's regular moons is similar or different to the movement of the planets around the Sun.

4. Draw a model to show what would happen to Jupiter’s 3 closest moons if Jupiter’s gravity suddenly stopped existing.

5. Which of the following is true of stars?

• there can only be 1 star in each solar system
• all stars resemble Earth's Sun
• all stars have solar systems
• stars can vary in brightness and size

6. Gliese 581 is a planetary system that's 20 light years away from Earth and has 4 planets moving around a star. How would you expect to find the planets orbiting the star?

• They will likely all have perfectly circular orbits around the star on different planes.
• The larger planets will likely move around the star and the smaller planets will move around the larger planets.
• They will likely be in a cloud around the star, but all orbiting the star.
• They will likely all be in a disk around that star with elliptical orbits.

7. Explain how your model shows the movement of Jupiter's regular moons is similar or different to the movement of the planets around the Sun.

8. What do the shape of Jupiter and its regular moons, the shape of the Solar System, and the shape of the Milky Way galaxy tell us about how these objects were formed?

9. We've discovered many exoplanets that are many light years away. Why don't these planets orbit the Sun?

10. How can we use gravity to make a connection between the following: the shape of the Milky Way system and the shape of the system that contains Jupiter and its moons. Why can models like the one provided be helpful to explain the movements of the solar system? Be sure to include two pieces of evidence from the model provided.

11. Explain how your model shows what would happen to these moons if suddenly there was no pull of gravity.

12. The difference between the two types of Diabetes is _____________.

• Type I involves the body's inability to produce insulin and Type II involves the body's inability to produce glucagon
• Type I involves the body's inability to produce glucagon and Type II involves the body's inability to produce insulin
• Type I completely eliminates the body's ability to produce insulin, but Type II may not completely eliminate insulin production
• nothing
