Jalyssa thinks that there are two variables (X and Y) that may affect the result of her experiment. She decides to change only variable X and let variable Y stay the same.
What can the she find out about the effects of variables X and Y?
If variable X affects the result of her experiment.
If variable Y affects the result of her experiment.
If both variables X and Y affect the result of her experiment.
She cannot find out if either variable X or variable Y affects the result of her experiment.
Miguel built a simple model showing Earth and the Sun and showed it to the class.
The diagram shows what Miguel constructed.
What is a benefit of Miguel’s model in helping others in the class understand the universe?
The model describes how Earth receives solar energy.
The model indicates the relative size of Earth and the Sun.
The model indicates the distance between Earth and the Sun.
The model describes the orbit that Earth follows around the Sun.
Addison's grandmother tells her that Riel Kentaurus is about 4.2 light-years away. Which of the following is the correct way for Daniela to understand this information?
A beam of light traveling from Earth to Rigel Kentaurus would take a little more than 4 years to get there.
The diameter of Rigel Kentaurus is just about four times bigger than the diameter of our Sun.
It takes a little more than 4 years for Rigel Kentaurus to make one orbit around the center of the galaxy.
The light coming from Rigel Kentaurus is approximately four times brighter than the light from our Sun.
Which of the following is the most accurate description of all known spaces?
The universe contains billions of galaxies, and each galaxy contains billions of stars.
The galaxy contains thousands of universes, and each universe contains millions of stars.
The universe contains hundreds of galaxies, and each galaxy contains thousands of stars.
The galaxy contains hundreds of universes, and each universe contains thousands of stars.
Space has a hierarchy of largest to smallest.
Which of the following accurately represent the hierarchy, from largest to smallest components?
Galaxy → universe → solar systems → planets
Universe → galaxies → solar systems → planets
Galaxy → solar systems → universes → planets
Solar systems → universe → galaxies → planets
The universe contains galaxies, planets, stars, and solar systems.
Look at the diagram - Which of the following statements is most true?
Not all galaxies contain stars.
Not all stars are a part of the Universe.
Our solar system contains several stars.
Our solar system contains only one star.
The HR Diagram classifies stars by temperature and Brightness.
Which of the following is a trend among the main sequence stars?
Most of the stars are white or red.
The larger stars emit light that is blue.
The hotter the star, the more brightly it burns.
Stars dimmer than the Sun are always smaller and cooler.
Based on the H-R diagram, which star is brighter than our Sun but has a lower temperature?
Sirius A
Sirius B
Aldebaran
Alpha Centauri B
Mrs. Whitworth heard on TV that Earth has recently experienced an increase in radiation from the Sun.
What can she conclude has recently occurred on the Sun to cause this increase in radiation?
An increase in solar flares.
An increase in the Sun’s mass.
A slowing of the Sun’s rotation.
An increase in the height of prominences.
What property of the Sun is illustrated by the model?
How strong the magnetic fields are
How the radiative and convective zones work
How long it takes for sunspots and solar flares to form
How the sun rotates faster at the equator than the poles
The universe is composed of billions of galaxies close to and far from the Milky Way.
What is the evidence that all distant galaxies are moving further from our position on Earth?
The shapes of the different galaxies
Shifts in the EM spectra received on Earth
Information about the orbit of other planets
Data collected on the composition of stars
Which of the following is NOT a characteristic of the big bang theory?
It explains how the universe formed.
It is a claim posed by an individual.
It could change as new evidence or information is discovered.
It is supported by scientific evidence and is agreed upon in the scientific community
A Scientist discovered a new element present on the surface of the moon and classifies it.
What method is he most likely to use to create a scientific explanation?
He uses experimentation.
chemical composition.
He collects samples from the surface.
He compares its properties to other elements he knows.
He measures it and draws a model for its chemical composition.
Malachi is describing how far away the nearest galaxy is from the Milky Way. Because he is describing distances between extremely large objects, like galaxies, Malachi must use which of the following units of distance?
Astronomical Unit
Kilometer
Light-year
Parsec
Which of the following best describes a galaxy?
A collection of all matter that exists.
A particle of debris in the solar system that does not act as a satellite of any planet.
A visible body of liquid or frozen droplets suspended above a planetary surface.
A massive system of stars, gas, dust, and dark matter bound together by gravity.
Richard describes a set of celestial objects that are relatively small and have a gaseous, or solid, rocky surface.
Which of the following objects is he describing?
Planets
Stars
Galaxies
Solar Systems
Which of the following best identifies a difference between
apparent magnitude and absolute brightness in stars?
Two stars can have the same absolute brightness but different apparent magnitudes, depending on how far away they are.
The absolute brightness of a star will remain constant over the life of a star, but its apparent magnitude will change daily.
The measurement of the absolute brightness of a star depends on the position of the observer; apparent magnitude does not.
Absolute brightness is always given as a numerical value; apparent magnitude has no numeric value.
Which of the following correctly orders the Sun’s layers from the innermost layer to the outermost layer?
Core, Convective Zone, Radiative Zone, Corona, Chromosphere
Core, Radiative Zone, Convective Zone, Chromosphere, Corona
Corona, Chromosphere, Convective Zone, Radiative Zone, Core
Corona, Convective Zone, Radiative Zone, Chromosphere, Core
What is an advantage of using an orbiting or deep space telescopes instead of an Earth-bound telescope to gather images?
Orbiting telescopes usually last longer because it is cold in deep space.
Telescopes launched into space are usually smaller than the ones found on Earth.
The images are usually clearer because they do not have to look through our atmosphere.
It is easier for scientists to make adjustments to an orbiting telescope than to a fixed telescope.
Being the hub of space exploration, people from different parts of the world move to Florida.
What effect will this have in Florida?
Increases in cultures
Decrease in employment
Decrease in tourism
Increase in financial debt
