The only time you can see stars other than the sun is:
at night
during the day
at noon
in the afternoon
The stars we see in the night sky are determined by:
our location on Earth and the time of year
the color of the stars
the age of the stars
the number of planets around the stars
We can't see stars, other than the sun, during the daytime because:
the brightness of the sun outshines them
stars disappear during the day
the stars are too far away during the day
clouds cover the stars during the day
We see different stars at different times of the year because:
the Earth orbits around the Sun, changing our view of the night sky
the stars move closer and farther from Earth throughout the year
the Sun blocks out different stars each night
the Moon's phases reveal different stars
The sun is up sometimes, but not other times, because:
the Earth rotates on its axis
the sun moves around the Earth
clouds cover the sun completely
the sun turns off at night
The moon is sometimes visible during the day because:
Its orbit sometimes places it in the daytime sky
the moon produces its own light
the sun is not as bright during the day
the earth's shadow covers the moon at night
If Earth is spinning, which way is up? Fill in the blank: Up will always be ________ from Earth, no matter where you are on Earth.
away
towards the center
parallel to the equator
in the direction of Earth's rotation
Why don't we see a lot of stars during the daytime?
brightness of the sun
distance of the moon
size of the Earth
movement of the stars
Constellation: ________
A collection of stars that make a picture in the sky
A single planet in the solar system
A type of cloud formation
A type of comet
Rotate: ________
To spin on a fixed point
To move in a straight line
To move around in a circle
To follow a path around something
Revolve: ________
orbit
rotate
spin
Day: ________
one rotation
one revolution
Year: ________
one revolution
one rotation
The stars we see in the night sky are determined by:
where Earth is located in its orbit
how far the moon is from Earth
the age of the stars
the number of planets around the stars
We see different stars at different times of the year because:
the Earth orbits around the Sun, changing our view of the night sky.
the stars move closer and farther from Earth throughout the year.
the Sun blocks out different stars each month.
the Moon's phases reveal different stars.
Samantha will not be able to see Orion during the summer because:
Orion is not visible in the night sky during the summer months.
Orion is only visible during the day in summer.
Orion disappears from the sky permanently in summer.

Explain the difference between daytime and nighttime.
Daytime is when your side of the Earth is facing the sun. Nighttime is when your side of the Earth is facing away from the sun.
Daytime is when the moon is visible. Nighttime is when the sun is visible.
Daytime is when it rains. Nighttime is when it is clear.
Daytime is when stars are visible. Nighttime is when clouds cover the sky.
What causes the daily pattern of daytime and nighttime?
The Earth's rotation (spin) causes us to go from daytime to nighttime.
The Earth's revolution around the Sun causes us to go from daytime to nighttime.
The Moon's phases cause us to go from daytime to nighttime.
Cloud movement across the sky causes us to go from daytime to nighttime.
If we are standing on the side of Earth, why don't we fall off?
Gravity is a force that pulls us toward the center of Earth.
Because the atmosphere holds us down.
Because the Earth is flat and we can't fall off the edge.
Because we are glued to the ground.
If Earth is spinning, which way is up?
Up will always be away from Earth, no matter where you are on Earth.
Up is always towards the North Pole.
Up is always towards the sun, regardless of your location.
Up changes depending on the time of day.
