Eclipses

Objective:

I can demonstrate the relative positions of the sun, Earth, and moon during the moon phases and to observe the changing appearance of the moon as seen on Earth. Learning Standard: ES 9. Describe lunar and solar eclipses, the observed moon phases, and tides. Relate them to the relative positions of the earth, moon, and sun.

Learning Standard:

ES 9.  Describe lunar and solar eclipses, the observed moon phases, and tides. Relate them to the relative positions of the earth, moon, and sun.

Eclipses:

Lunar Eclipse

i. Earth is between the sun and moon

ii. Earth’s shadow is cast on the moon

iii. Moon appears red due to light from the sun bending through the Earth’s atmosphere

iv. Occurs during a full moon phase

vi. Everyone on the nighttime side of Earth can see the lunar eclipse

vii.If the moon falls into the umbra of the shadow, there is a total lunar eclipse

viii. If the moon falls into the penumbra of the shadow, there is a partial lunar eclipse

See Figure A

Solar Eclipse

i. Moon is between the Sun and Earth

ii. Moon’s shadow is cast on Earth

iii. Occurs during a new moon phase

iv. Only seen during the day

v. Anyone in the umbra of the shadow sees a total solar eclipse

vi. Anyone in the penumbra of the shadow sees a partial solar eclipse

vii. Anyone outside the shadow sees NO eclipse

Lunar eclipses do not occur during every full moon and solar eclipses do not occur during every new moon

i. The moon does not orbit earth in one plane (sometimes it passes at a point higher or lower than other times)
