Motions of the Earth, Moon, and Sun
Enduring Understandings:
Essential Questions:




The moon’s orbit and its change of position relative to the
Earth and sun result in different parts of the moon being
visible from Earth.
A solar eclipse is when the Earth moves into the shadow of
the moon; a lunar eclipse is when the moon moves into the
shadow of the Earth.
Gravitation force between the Earth and the moon causes
daily oceanic currents; spring and neap.


How does the moon’s orbit and its change of position relative
to the Earth and sun result in different parts of the moon
being visible from Earth.
What are the relative positions of the earth, moon and sun
when a solar or lunar eclipse occurs?
How does the gravitation force between the Earth and the
moon causes daily oceanic currents; spring and neap tides?
