Preliminary Topics

Before students can understand the reason for phases, they need to understand:

The Moon orbits the Earth

The Moon orbit at an angle with respect to the Earth’s orbit around the Sun

The Moon doesn’t shine on its own; it reflects sunlight

The scale of the Moon and Earth’s sizes and distance

Please go through Earth and Moon statistics before trying to cover the reason for phases or eclipses.

Slide 4

 

Phases--Causes

The Sun shines on the Moon.

When the sunlight reflects off the Moon’s far side, we call it a New Moon

When the sunlight reflects off on the Moon’s near side, we call it a Full Moon

Between New and Full, we see parts of the daytime side of the Moon.

Eclipses

The Sun and Moon occasionally line up so that we have an eclipse.

These eclipses happen every year

To see a solar eclipse, you need to be on a particular part of the Earth

Slide 8

 

When the Earth’s shadow covers the Moon, we have a lunar eclipse

Slide 9

 

Three types of Lunar Eclipses

Penumbral lunar eclipse—the Moon only passes through the penumbra of Earth’s shadow

Partial lunar eclipse—part of the Moon passes through the umbra of Earth’s shadow

Total lunar eclipse—the entire Moon passes through the umbra of Earth’s shadow
