Evaporation, condensation, and
precipitation are parts of the

water cycle.

Can you

explain how
the water

cycle happens?

evaporation

When water heats up,
some of it changes into
a gas we cannot see.

Water can evaporate,
or change from a liquid
to a gas.

The gas travels in the
air as water vapor.

9

condensation

Water vapor rises in warm
air.

As the air cools, it can no
longer hold the water
vapor.

So the water changes
again! This time, the water
vapor will condense and
will fall as a precipitation.

precipitation

- Water that falls to

Earth from clouds.

1. Rain
2. Snow
3. Sleet
4. Hail

Day and Night

Day and Night

How does Earth’s
motion cause day

and night?

When one side of the
Earth faces the Sun, it
is day. The side that
does not face the sun

is night.

Earth’s rotation

causes day and night

Rotation means

spinning.

This is the imaginary line
that Earth rotates around.

Every 24 hours, Earth

makes one full turn on its

axis.

Each season has a
different weather.

What are the 4

seasons?

Seasons

In fall the air can

become cool. Leaves on

some trees change

color and fall off.

Fall/Autumn

In winter the air is cold.

In some places it

snows. Animals must

keep warm. Some birds

fly to warmer places.
People wear warmer

clothes.

Winter

The weather becomes

warmer. There are

winter homes.

Spring

Summer is the hottest
season. There are more

hours of sunlight in a

day.

Summer

What season comes

after summer?

The seasons start all over again!

Did you know
that the Earth

moves around the

Sun?

What causes the

seasons?

The path Earth takes

around the Sun is called

its orbit.

Earth takes 365 days, or
1 year, to orbit the Sun.

Orbit

As Earth moves around
the Sun, the tilt of the

Earth causes the seasons.

The part of Earth that tilts
toward the Sun is warmer.

The part that tilts away
from the Sun is colder.

Earth’s axis is tilted.

As Earth moves around
the Sun, the tilt of the

Earth causes the seasons.

Seasons happen because:
1. Earth is tilted on its axis
2. Earth orbits around the sun

The Moon is the Earth’s
closest neighbor in space.

Why does the Moon seem to

change shape?

It does not really change shape.

It seems to change its shape because of the

different amounts of sunlight it receives.

Why can we see the
Moon from the Earth?

Each shape of the Moon we see is

called a phase.

first

The phases appear in the same order

every month.

moon

Stars are made of hot

glowing gases.

It gives off heat and light.

Stars can form constellations.

From the Earth, stars look tiny

because they are far away.

The sun is the closest

star to the Earth! It is an

average-sized star. It

looks large because it is

close to the Earth.
