Essential Questions:

Reflect on the
Essential Questions
before you dive in…

1. If you were quizzed
today, which questions
would you know the
answers to already?

2. Which questions would
you need to learn more
about to answer
confidently?

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?

Eclipses

• 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

• Two main types: solar and

lunar

​Eclipse Definition

Open Ended

What is an eclipse?

© Kesler Science, LLC

Eclipses

• Occurs when the Moon

passes between Earth and
the Sun totally or partially
obscuring Earth’s view of the
Sun

• The Moon casts a shadow on

part of Earth.

• Occurs during the new moon

phase

• Occurs during daylight

When does

a solar
eclipse
happen?

​Solar Eclipse

Word Cloud

What moon phase must it be for a solar eclipse to occur?

Eclipses

Lunar Eclipse

• Occurs when Earth passes

between the Moon and the
Sun

• Earth casts a shadow on the

Moon blocking all or a
portion of it

• Occurs during the full moon

phase

• Occurs at night

When does a lunar

eclipse happen?

Multiple Select

Describe the relationship between the Sun, Earth, and Moon during a lunar eclipse. (select 2)

• The Moon passes between the Earth and the Sun

• The Earth passes between the moon and sun

• occurs during a full moon

• occurs during a new moon

Eclipses

Solar Eclipses

• Total Solar

• Partial Solar

• Annular Solar

There are different types of solar

and lunar eclipses:

Lunar Eclipses

• Total Lunar

• Partial Lunar

© Kesler Science, LLC

Eclipses

Total Solar Eclipse

When the Moon blocks out
the Sun entirely

When does a total
solar eclipse occur?

© Kesler Science, LLC

Eclipses

Partial Solar Eclipse

When the Moon blocks out a
portion of the Sun

When does a partial
solar eclipse happen?

© Kesler Science, LLC

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

horizontal line

This is what they would
see from each location

Positions of Solar

Eclipses

A. Total solar

B. Annular
C. Partial solar

Eclipses

The horizontal line

represents the surface

of Earth. Describe
how the distance
between Earth and
the Moon affects the

type of eclipse.

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

What part of Earth’s

shadow does the Moon
pass into during a total

lunar eclipse?

© Kesler Science, LLC

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

What part of Earth’s

shadow does the Moon

pass into during a partial

lunar eclipse?

Multiple Choice

The phase of the moon has nothing to do with the type of eclipse that can occur.

• true

• false

Eclipses

• Umbra

• Penumbra

What types of shadows cause eclipses?

Did you know?
“Umbra” is Latin

for “shadow”

© Kesler Science, LLC

Eclipses
Umbra

• The darkest part of a

shadow

• The cone-shaped region of

full shadow cast by Earth
and the Moon during an
eclipse

Using our solar system
as an example, what is

the light source?

Eclipses

Umbra/Solar Eclipse

• When the umbra from the Moon’s shadow

touches Earth, you have a total solar eclipse.

• The total solar eclipse is labeled in the diagram

© Kesler Science, LLC

Eclipses
Umbra/Lunar Eclipse

•The entire disk of the Moon
is darkened as it passes
through the umbra

Comparing the lunar
eclipse with the solar

eclipse, name one
similarity and one

difference you notice.

Eclipses

Penumbra

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

Compare the umbra
and the penumbra.

© Kesler Science, LLC

Eclipses

Penumbra/Solar Eclipse

• When the penumbra of the Moon’s shadow touches Earth you have a partial solar eclipse

• The partial solar eclipse is labeled in the diagram below

© Kesler Science, LLC

Eclipses
Penumbra/Lunar
Eclipse

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

Comparing the partial
lunar eclipse with the

partial solar eclipse, name

one similarity and one
difference you notice.

Eclipse INB Template

1. cut out the template

2. glue it to your journal along the skinny tab

3. lift flaps and add descriptions
