SeasonsMoon Phases

Why do we have seasons?

The tilt of the Earth’s axis

When the Southern Hemisphere is receiving the most concentrated sunlight, what season is it in the

Northern Hemisphere?

Winter

Draw a picture that illustrates winter in the Northern

Hemisphere.

What is a rotation and how long does it take the Earth to make 1

complete rotation?

Earth spinning on its axis (causes day and night)

1 rotation = 24 hours (1 day)

Draw a picture illustrating all 4 seasons with the sun

in the middle

What season is illustrated in the picture

below?

Summer

What is a revolution and how long is 1 Earth

revolution?

Revolution = Earth moving around the sun

1 Revolution = 1 year (365 days)

What could we change to decrease the length of day?

Increase the speed of the Earth’s rotation

If the Northern Hemisphere is getting indirect sunlight and the days are shorter, what season is it in the southern

Hemisphere?

Summer

Draw all 8 phases of the moon in order starting with the New

Moon:

What does the word waxing mean and draw a picture

representing waxing.

Waxing = bigger, brighter (light on the

right)

What is a spring tide? When does a spring tide

occur?

-Tide that has the BIGGEST change in tides

-Occurs at New & Full Moon

During a new moon, what is the position of Earth, moon

and sun?

The moon is in between the Sun and the Earth

Looking at the diagram below, how long does it

take to get from point 4 to point3?

3 weeks (21 days)

Where is the sun located in the diagram below? How did you

know?

By moon #4; the sun goes next to the New

Moon

Based on the phase of the moon on June 27 (as pictured below),

what phase of the moon would be shown on July 3?

Full Moon

What causes the changes in the lunar

cycle?

The relative position of the moon, sun, and Earth

In what shape does Earth orbit the sun??

Ellipse

What percent of the Earth is lit up at any

time?

50%

At what positions are we going to have the biggest change in

tidal range?

Positions 2 & 4

What keeps Earth and the moon in orbit?

Gravity

Draw a picture that represents the next 3 phases of the moon:

What part of the Earth receives the most

direct light from the sun?

Equator

Draw a diagram that represents a Spring

Tide

At what position in the diagram below do we have a full moon? How did you

know?

Earth

1

2

3

4 Sun

Position 4 – it’s furthest from the sun
