wide
elliptical orbits
b)
circular orbits
c)
wavy orbits

unknown orbits
5.
Why is the distance from the stars important?
a)
Distance
would make the planet neither too hot nor too cold for human habitation, and
water could exist in liquid form.
b)
Being to close to the planet's star would produce light that was too bright.
c)
Distance from the stars would determine how many planets were in the system.
6.
Will you feel lighter or heavier on Kepler 1647 b?
a)
Kepler-1647 b’s mass is very large, about 10 times the mass of Earth.
This will cause gravity on this planet to be very strong.
b)
Kepler-1647 b’s mass is very small, about half the mass of Earth.
This will cause gravity on this planet to be very weak.
c)
Kepler-1647 b’s mass is very large, about the same as the mass of Earth.
This will cause gravity on this planet to be almost the same as Earth's gravity.
7.
Which planets in our solar system spin fast?
a)
Gaseous Planets
b)
Terrestrial Planets
c)
Dwarf Planets
d)
Planets with Moons
8.
Why do balls fall to the ground after being thrown upwards?
a)
It is being acted on by an invisible force called gravity.
b)
A physical property called momentum causes the ball to curve down.
c)
The orbit of the Earth, along with the spin of the planet causes the ball to come back down.
9.
How would you compare the merry- go-round example to the Earth and you?
a)
This analogy helps us visualize the gravitational attraction between Earth and you.
b)
The merry-go-round spins like a satellite in orbit.
c)
This analogy helps us visualize the relationship between the Moon's Phases and the tides.
10.
How is the merry-go-round and Earth different?
a)
As long as you hold on, you
will stay on the merry-go-round. Don’t let go! You will fly off and land on the
ground.
b)
The merry-go-round is much smaller than the Earth, so it has a similar force pushing you off of it.
c)
You can ride a merry-go-round with no hands just like you ride the planet Earth without anything to strap you down.
11.
What makes the ocean tides rise and fall?
a)
The gravitational pull of the
Moon makes the ocean tides rise and fall.
b)
The gravitational pull of the Sun makes the ocean tides rise and fall.
c)
Weather satellites like HARPA control the tides to aide in shipping commerce.
12.
Why do you think all the planets go around the sun?
a)
The Sun's attraction is very strong. All objects in the solar system orbit around the Sun.
b)
The Sun's attraction is weak strong. Not all objects in the solar system orbit around the Sun.
c)
Object will lots of mass orbit around the Sun, however objects with very small masses orbit around planets.
13.
Why does the Earth’s gravity have a more powerful effect on you than the sun’s gravity?
a)
The gravitational pull of the Sun has little effect on you because the distance is so large.
b)
The gravitational pull of the Earth has little effect on you because the distance is so small.
14.
What is the universe?
a)
The universe is everything you can sense, feel,
and measure.
b)
The universe is everything outside of our Solar System.
c)
The universe is everything outside of the Milky Way.
15.
What is the name of our galaxy?
a)
Our galaxy is called the Milky Way galaxy
b)
Our
galaxy is called the Andromeda galaxy
c)
Our
galaxy is called the Grand spiral galaxy.
d)
Our galaxy is called the Whirlpool galaxy.
16.
How big is the universe?
a)
No one
is for certain how big the exact size of the universe really is.
b)
The universe is approximately 400 billion light years wide.
c)
The universe is 150 million Astronomical Units wide.
d)
The size of the universe can not be calculated.
17.
What is happening to our universe?
a)
Recent evidence suggests that the universe is actually expanding.
b)
Recent evidence suggests that the universe is actually getting smaller.
c)
Recent evidence suggests that the universe is actually moving into a black hole.
d)
Recent evidence suggests that the universe is actually staying the same.
18.
What is the Big Bang?
a)
The
current theory of the beginning of the universe suggests that it all started
with a period of rapid expansion known as the Big Bang, 13.7 billion years ago.
b)
An explosion that forms a star.
c)
The
current theory that suggests that the universe is not moving and changing.
d)
The current theory that suggests that inside the core of stars is a generator that produces light and heat. The Big Bang explains how this happens.
19.
How long after the big bang were stars born?
a)
400 million years
b)
Very soon after
c)
Scientists are not sure.
d)
2 to 20 thousand years.
20.
What did the sun start out as?
a)
a huge cloud of gas and dust called a nebula
b)
The result of two or more planets colliding
c)
A collapsed black hole
21.
Why can’t you feel the gravitational force between you and a piece of paper?
a)
the mass of both you and the paper are quite small compared to the mass of the Earth.
b)
the mass of both you and the paper can be detected if you move close enough together.
c)
The mass of the Sun overrides the gravity of both the planet Earth and the piece of paper.
d)
The mass of the paper, combined with the distance from you has a significant effect on the paper, but not on you.
22.
Why does the sun produce light and heat?
a)
A nuclear reaction inside the Sun's core.
b)
The sun is made of a material that resists being cold.
c)
A chemical reaction between the Sun and Earth's atmosphere creates the light and heat that we feel.
23.
Why do we use Light Years to measure distant objects?
a)
The distances between astronomical bodies are so great that they are nearly unimaginable compared to the distances that we use in our everyday lives.
b)
Space craft like the Space Shuttle Columbia travel great distances measured with Light Years.
c)
Astronomical Units are too short.
24.
Does light travel instantaneously (right away)?
a)
Light does not travel instantaneously; it takes time for light to travel through the universe.
b)
Light travels instantaneously; it takes no time for
light to travel through the universe.
25.
What is the distance that light travels in one year?
a)
10 trillion km
b)
10 million km
c)
10 billion km
d)
10,000,000,000 km
26.
When we look at images of astronomical bodies are we looking at them in the present?
a)
Looking at current images of distant astronomical bodies
is like looking back in time; the light that we see does not show what the
object looks like now but how it looked when the light was emitted.
b)
Looking at current images of distant astronomical bodies
is like looking forward in time; the light that we see does not show what the
object looks like now but how it will look when our galaxies align.
c)
Looking at current images of distant astronomical bodies
is like looking at a our current point in time; the light that we see shows what the
object looks like now.
