EclipsesPresented by Kesler Science

1. Can you describe how the positions of the Sun, Moon, and Earth determine the type of eclipse?

2. Can you model how the shadow cast in an eclipse causes partial and total eclipses?

Essential Questions:

Eclipses

Eclipse• The total or partial obscuring of a planet, star, or moon by another celestial object• The passing of a celestial object into the shadow of a planet, star, or moon• Types: solar and lunar

Eclipses

Solar Eclipse•Occurs when the Moon

passes between the Earth and the Sun totally or partially obscuring Earth’s view of the sun• The moon casts a shadow on

part of the Earth.•Occurs during the new moon

phase•Occurs during daylight


Eclipses

Lunar Eclipse•Occurs when the Earth

passes between the Moon and the Sun.• The Earth casts a shadow

on the Moon blocking all or a portion of it. •Occurs during the full

moon phase•Occurs at night


Quick Action - Eclipses

Get with a partner and draw the Sun, the Earth, and two moons with the moons in new moon phase and full moon phase.

Which Moon phase indicates a solar eclipse?Which Moon phase indicates a lunar eclipse?

Eclipses


Total Solar Eclipse•When the moon blocks out the Sun entirely

Eclipses


Partial Solar Eclipse•When the moon blocks out a portion of the Sun

Eclipses


Annular Eclipse•When the Moon is at its furthest point in orbit• Its shape will not cover the Sun completely.• This is when you can see a thin ring of light emerging from the outside rim of the moon.

Eclipses


Solar Eclipses

•A Total solar•B Annular•C Partial solar

Eclipses


Total Lunar Eclipse•Occurs when the moon completely passes into the darkest part (umbra) of Earth’s shadow•Only occurs during full moon phase•Occurs at night

Eclipses


Partial Lunar Eclipse•Occurs when the moon

passes into the lightest part (penumbra) of Earth’s shadow.•Occurs only at Full moon

phase•Occurs at night

Eclipses


Umbra• The darkest part of a shadow• The cone-shaped region of full shadow cast by Earth and the Moon during an eclipse.

Eclipses


Umbra/Solar Eclipse•When the umbra from the Moons shadow touches Earth, you have a total solar eclipse.•Point C in the diagram

Eclipses


Umbra/Lunar Eclipse•The entire disk of the Moon is darkened as it passes through the umbra

Eclipses


Penumbra•The area of partial shadow surrounding the total shadow (umbra) cast by the Earth or Moon.

Eclipses


Penumbra/Solar Eclipse•When the penumbra of the Moon’s shadow touches Earth you have a partial solar eclipse•Point B in the diagram

Eclipses


Penumbra/Lunar Eclipse•When the penumbra of the Earth’s shadow touches the Moon you have a partial/penumbral lunar eclipse

Check for Understanding

Write a short essay to answer the following questions.1. What is an eclipse?2. What is the difference between solar

and lunar eclipses?3. Explain which moon phase happens

during a lunar/solar eclipse and why it will not be in any other phase.


Check for Understanding

Can you…1. Describe the different

types of eclipses?2. Model the differences

between lunar and solar eclipses.

3. Model umbra and penumbra in a solar/lunar eclipse.
