The force of attraction, or pull, between any two
objects.
What is gravity?
One complete trip around the
Sun.
What is a revolution?
This is how long it takes Earth to make
one revolution around the Sun.
What is 365.25 days?
This is how long it takes Earth to
make one rotation on its
axis.
What is 24 hours?
The tendency of a moving object to keep moving in a
straight line.
What is inertia?
The pull of the Moon’s gravity on
Earth causes these in large bodies of water.
What is a tide?
The shape and appearance of the Moon at a
particular time.
What is a phase?
This is what happens when
the Moon passes directly between
the Sun and Earth.
What is a solar eclipse?
This is what happens when
the Moon is hidden by
Earth’s shadow.
What is a lunar eclipse?
Name and draw the eight stages
of the Moon, starting with a
new moon.
What is:
An instrument that is used to see things that are far away.
What is a telescope?
A large object that orbits a star
but does not give off its own
light.
What is a planet?
Most of these burn up before
they reach Earth’s surface.
What are meteors?
Most of these are located between Mars and Jupiter.
What are asteroids?
The surfaces of the inner
planets are mostly made of
this.
What is rock?
A natural satellite that
orbits a planet.
What is a moon?
An object in space that
circles around another object.
What is a satellite?
This is made up of a mixture of frozen gases, ice, dust, and
rock.
What is a comet?
Saturn’s rings are composed of
these two things.
What is ice and rock?
Explain how scientists explore the Moon and planets in
the solar system.
What is through the use of space probes (a vehicle carrying
instruments sent to explore objects in space) and rovers (small robot
cars)?
An object in space that
produces its own heat and light.
What is a star?
An exploding star.
What is a supernova?
This is about 5.9 billion miles.
What is a light-year?
All stars form out of this.
What is a nebula?
The stage of a star’s cycle
where it is small and dense.
What is a white dwarf?
Patterns formed by stars.
What are constellations?
An object in space that has a
gravitational pull so strong that light cannot escape it.
What is black hole?
These hold billions of stars.
What is a galaxy?
This forms a new nebula.
What is supernova?
Draw a picture of these four galaxies:
ovoid elliptical, irregular, disc-
shaped elliptical, and spiral.
