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.
