BIG BANG THEORY
What does the Big Bang Theory explain?
The origin and expansion of the universe.
What is the name of our home galaxy?
The Milky Way Galaxy.
Which model puts the Earth at the center of the solar system?
The Geocentric model.
What force pulls objects toward each other based on their mass and distance?
Gravity.
What is our school Mascot?
A Charger
Did the Big Bang happen as an explosion in space or an expansion of space itself?
An expansion of space itself.
What shape/type of galaxy is the Milky Way?
A barred spiral galaxy.
Which model puts the Sun at the center of the solar system?
The Heliocentric model.
What property of matter describes an object's tendency to resist a change in its motion?
Inertia.
What are our school colors?
Navy Blue and Yellow (Gold)
What piece of evidence shows that distant galaxies are moving away from us?
Redshift (or the Doppler effect applied to light).
Where is our Solar System located within the Milky Way?
On an outer spiral arm (the Orion Arm), about halfway between the center and the edge
Name the scientist famous for popularizing the heliocentric model during the Renaissance.
Nicolaus Copernicus (or Galileo Galilei).
How do gravity and inertia work together to keep planets in orbit around the Sun?
Inertia keeps the planet moving forward in a straight line, while gravity pulls it inward toward the Sun, resulting in a curved orbit.
What are the expectations in the hallway?
Voice level Zero and Walk to the right of the hallway
What is the leftover thermal radiation from the Big Bang called that fills the universe?
Cosmic Microwave Background Radiation (CMBR).
What massive object sits at the very center of the Milky Way, around which everything orbits?
A supermassive black hole
What key evidence did Galileo discover using his telescope that disproved the geocentric model?
The moons of Jupiter (proving not everything orbits Earth) or the phases of Venus.
What would happen to Earth's path if the Sun's gravity suddenly disappeared?
Earth would fly off into space in a straight line due to inertia.
What year class in the BEST class? (2023,2033,2031,2016)
2033
Roughly how old is the universe according to the Big Bang Theory?
Approximately 13.8 billion years old.
Put these in order from smallest to largest: Universe, Earth, Solar System, Milky Way Galaxy.
Earth → Solar System → Milky Way Galaxy → Universe.
Compare the two models: what is one major similarity and one major difference between them?
Both attempt to explain the motion of celestial bodies/planets. Difference: Geocentric puts Earth at the center; Heliocentric puts the Sun at the center.
If you increase the mass of an object, what happens to its gravitational pull? What if you increase the distance between two objects?
Increasing mass increases gravity; increasing distance decreases gravity.
What grade is the best grade at BUNCHE Middle School?
Sixth Grade of course !
