Crescent – the phases where the moon is less than half light.
Gibbous – the phases where the moon is more than half light
Waxing essentially means "growing" light

Rhyme time –
Waxing moons are growing bright, waning
moons have shrinking light!

• The daily rise and fall of Earth’s waters
on the shorelines
• Caused by the gravitational pull between
the Earth, Moon, and Sun
Spring Tides
–Occur twice a month, when the Sun
and Moon are lined up
–This combined gravity creates the
STRONGEST pull on the water

All in a LINE 
 All in a LINE
The SUN,
EARTH, and
MOON are
all in line!
Neap Tides
–Occur twice a month, when the Sun
and Moon form right angles with Earth
–This combined gravity creates the
WEAKEST pull on the water

The SUN and
Earth are in line
but the MOON
is at a right
angle!
• Is kept in orbit by Earth’s gravity
• Is visible ONLY because it reflects sunlight
– DOES NOT generate its own light!
• No atmosphere = impacted by many
meteoroids

• As Earth revolves around the Sun (365 ¼ days),
the Moon revolves around the Earth (28 days)
• The phase of the moon you see depends on
how much of the sunlit side of the moon is
facing Earth
What is today’s phase
of the moon?

Step 1
Draw arrows curving
toward the left. This
shows the direction
the spinner turns!
Step 2
Cut out the circle by
cutting along the
dotted lines. CUT OUT
ALL OF THE TRIANGLE!
Step 3
Write the word
“WANING” on the left
side and “WAXING”
on the right side of
your paper
Step 4
Draw a picture of the
SUN at the bottom of
the page (under the
NEW MOON)

b. Push it through the
moon phases sheet
c. Fold the straight
pieces down
