Final Jeopardy
$100 Question from Lives of Stars
The length of a star’s “life” depends on its…
mass
$200 Question from Lives of Stars
What type of star “lives” longest (be specific)?
A low-mass red star
$300 Question from Lives of Stars
What two types of stars eventually supernova?
Blue stars and white stars
$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
$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
$100 Question from Sun
What generates the sun’s energy?
Nuclear fusion
$200 Question from Sun
What is the sun made of?
Plasma/superheated gas
$300 Question from Sun
What creates the sun’s magnetic field?
Charged particles
$400 Question from Sun
Why must nuclear fusion occur in the sun’s core?
Because it has the most heat and pressure
$500 Question from Sun
What happens when two magnetic regions of the sun connect?
Prominence (solar flare acceptable)
$100 Question from Sun’s Layers
What’s part E?
Core
$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
$300 Question from Sun’s LayersOn 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
$400 Question from Sun’s Layers
What part of the sun do we see on a normal day?
The photosphere
$500 Question from Sun’s Layers
What gives the chromosphere its pinkish/reddish color?
Hydrogen emits red when heated
$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
$200 Question from Exploring the Solar System
What two forces keep planets orbiting around the sun?
Inertia and gravity
$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!
$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
$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 equalComet Oncé: sun’s gravity is stronger than its inertia
$100 Question from Potpourri
What two factors determine how strong an object’s gravity is?
Mass and distance
$200 Question from Potpourri
Does a basketball or a Ping-Pong ball have more gravity? Why?
Basketball, because it has more mass
$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.
$400 Question from Potpourri
What is solar wind?
When charged particles from the sun escape its atmosphere and travel across the solar system.
$500 Question from PotpourriExplain 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
Final JeopardyWhat causes the Northern lights?
Final Jeopardy Answer
Charged particles from solar wind interacting with Earth’s magnetic field.
