Catching the Rays

• Sunlight travels in rays that move away from the
  sun
• the suns rays do not light up space only the
  solid objects they hit, which is why half of the
  Earth is always dark

Moonlight Reflections on Sections

• The moon is shaped like a ball but every night
  seems to change shape
• these changes are called phases of the moon and
  repeat a pattern every 29 1/3 days (one full
  orbit of Earth)
• The shape of the moon we see depends on how
  much of the sunlit side of the moon faces Earth.

5
Making A Shadow

• A solar eclipse takes place when the moon moves
  directly between the sun and Earth so that all
  three are lined up in a straight line
• during a solar eclipse, the moon blocks sunlight
  from reaching Earth, making a shadow of the moon
  on Earth

Making A Shadow continued...

• Sometimes the Earth passes between the moon and
  the sun that is called a lunar eclipse
• a lunar eclipse casts a shadow on the moon

7
Gravity Orbits

• When two objects attract each other, the object
  with less mass will move more easily, which is
  why the moon orbits the Earth
