3. $100 Question from Lives of Stars The length of a star’s “life” depends on its… mass

4. $200 Question from Lives of Stars What type of star “lives” longest (be specific)? A low-mass red star

5. $300 Question from Lives of Stars What two types of stars eventually supernova? Blue stars and white stars

6. $400 Question from Lives of Stars Put the following stars in order of mass from least to greatest: white, yellow, blue, red Red, yellow, white, blue

7. $500 Question from Lives of Stars A long time ago, in a galaxy far, far away, there was a neutron star, R2D2, and a black hole, C3PO. Which one had more mass at the beginning of its “life?” C3PO

8. $100 Question from Sun What generates the sun’s energy? Nuclear fusion

9. $200 Question from Sun What is the sun made of? Plasma/superheated gas

10. $300 Question from Sun What creates the sun’s magnetic field? Charged particles

11. $400 Question from Sun Why must nuclear fusion occur in the sun’s core? Because it has the most heat and pressure

12. $500 Question from Sun What happens when two magnetic regions of the sun connect? Prominence (solar flare acceptable)

13. $100 Question from Sun’s Layers What’s part E? Core

14. $200 Question from Sun’s Layers On the diagram, which is the part where energy radiates outward from where nuclear fusion happens? A—the radiation zone

15. $300 Question from Sun’s Layers On the diagram, which is the part of the sun where energy and matter create circular currents as they are heated and cool? (Look carefully at the diagram.) B—the convection zone

16. $400 Question from Sun’s Layers What part of the sun do we see on a normal day? The photosphere

17. $500 Question from Sun’s Layers What gives the chromosphere its pinkish/reddish color? Hydrogen emits red when heated

18. $100 Question from Exploring the Solar System What did Copernicus contribute to our understanding of the universe? Developed heliocentric model—thought sun was in center

19. $200 Question from Exploring the Solar System What two forces keep planets orbiting around the sun? Inertia and gravity

20. $300 Question from Exploring the Solar System How did Galileo’s discovery of Jupiter’s moons support the heliocentric model? He showed that not all objects in space orbit the Earth!

21. $400 Question from Exploring the Solar System If you give your sister a hug while your dad waits for you in the car, on which person are you exerting a stronger gravitational pull? Why? Your sister, because she’s closer

22. $500 Question from Exploring the Solar System Comet Bey orbits the sun. Comet Oncé comes toward the sun and then goes in and burns up. Why does Bey stay in orbit but Oncé does not? Comet Bey: inertia and gravity are equal Comet Oncé: sun’s gravity is stronger than its inertia

23. $100 Question from Potpourri What two factors determine how strong an object’s gravity is? Mass and distance

24. $200 Question from Potpourri Does a basketball or a Ping-Pong ball have more gravity? Why? Basketball, because it has more mass

25. $300 Question from Potpourri How did Kepler contribute to our understanding of the solar system? Applied math to detailed observations of the planets’ movements to show that planets orbit in elliptical, not circular, shapes.

26. $400 Question from Potpourri What is solar wind? When charged particles from the sun escape its atmosphere and travel across the solar system.

27. $500 Question from Potpourri Explain why we can see pinkish light on the sun during an eclipse but not on a normal day. Because the photosphere is blocked during an eclipse, so it doesn’t “overpower” pink light of the chromosphere

28. Final Jeopardy What causes the Northern lights?

29. Final Jeopardy Answer Charged particles from solar wind interacting with Earth’s magnetic field.
