Universe Info
The Theory that the universe is expanding is named what?
HINT: There is a show named after it
Big Bang Theory
The first stage of a life cycle of any star type is what?
A star spends a majority of it's life in this region
*HINT: the Sun is an example
Main-Sequence
Ms. B. is getting married on what day?
Nov 2, 2024
This property can be shown by color
Temperature
What are galaxies?
Stars, dust, and gasses held together by gravity
What are the two (really three) different types of life cycles discussed.
BONUS IF YOU DESCRIBE ALL THREE.
1. Low mass
2. Medium mass
3. High mass
*HINT: Betelguese is an example
Red Supergiant
How is practice work labeled in Infinite Campus
P1 or P2 - depending on the assessment needing to be covered
mass
What are the main elements creating the composition of the universe?
hydrogen and helium
What are the two elements that compose most stars?
Hydrogen and Helium
Stellar Nebula
What is the difference between a theory and a law?
Answers will vary.
Example: Law - accept to be true
Theory - has evidence to support it, but not enough to accept
Parallax angles (shifts) account for an angle to determine this property of stars
distance
How is the redshift used as a piece of evidence in universal expansion?
Galaxies, and everything in them, appear more red throughout time
Describe one difference between a low mass and high mass life cycle (USING SCIENTIFIC LANGUAGE)
*Answers will vary
1. Remnant difference
2. Expansion differs (reaches different stages)
This star type/event is the result of a Supergiant expanding too greatly, collapsing on itself, and bursting into a great explosion with two remnants.
SUPERNOVA
True or False: Valentines day is Ms. B's favorite holiday.
BONUS if you can name it.
FALSE: HALLOWEEN
A constellation allows for this property of stars to be determined
LOCATION
Name the theory which describes the "reverse" of the Big Bang; galaxies colliding into one another and becoming a ball of hydrogen and helium
HINT: Ms. B believes this theory
THE BIG CRUNCH
The remnants:
Low-Mass: does note expand large enough for a red giant to happen and instead, a white dwarf is created
Middle-Mass: expands to a red giant, collapses on itself for a planetary nebula
A remnant of a high mass star life cycle; is dense enough with strong enough gravity that light does not escape
black holes
In order to have your weekly folders marked as "turned in" on Schoology, you need to look for what?
HINT: Ms. Breitsprecher also looks for this
THE GREEN CHECKMARK
This value is located on the "y" axis of the HR-Diagram; representing the absolute magnitude of a star
LUMINOSITY
