How to draw a solar eclipse:

1) On a piece of paper, draw a Sun on the far left, an Earth on the far right, and a moon close to the Earth. All bodies need to be drawn in a straight line.

2) Find a point at the top of the Sun and the top of the Moon. Using a ruler, draw a line to connect the points and continue line to the Earth.

3) Now from the same point on the Sun, find the point at the center of the bottom of the moon and draw a line.

6) Shade in the penumbra, this one is shaded pink. Under this part of the shadow you would experience a partial eclipse.

A total solar eclipse is very brief. It lasts only ______________. It is, however, one

of the most awe inspiring events in all of nature. The sky becomes _____ and the temperature may _____ several degrees.

The next graphic shows the path for different solar eclipses through 2025.

Notice there are two solar eclipses that cross the

United States (2017 and 2024).

A special feature during a total solar eclipse is called ____________. These

are bead-like bursts of light that appear about _________ before and after totality during a solar eclipse.

Baily's beads15 seconds

Baily's beads are caused by sunlight shining through valleys on the edge of the _____. They

roughly resemble a string of beads.

Moon

Another interesting

feature during a solar eclipse

is called a ____________. This is a large burst of light that appears

after totality.

“Diamond Ring”

Solar eclipses give scientists

a unique opportunity to view features of our Sun. During an eclipse the Sun’s ______ and Sun’s

__________ can be observed and studied.

corona

prominences

Here a solar prominence is visible during a total solar eclipse. The

prominence appears as a ___ cloud and consists of ionized ____ that is projecting above the surface of the

sun.

red gas

The moon’s orbit around the Earth is an _______ shape. If the eclipse

happens during the moon’s apogee, its ______ distance from the Earth, the moon’s shadow is a bit smaller and the result is an _______ eclipse.

ellipticalfarthest

annular

During an annular eclipse, an outer ring of the Sun will be ______ around

visible

This illustration shows an ________ shadow produced during this type of eclipse .

full

During the total eclipse, the Moon is still _____. The Moon will actually become a variety of colors from

lasts over _______. The shadow from the Earth is _____ than the shadow that the Moon casts on the Earth

during a solar eclipse.

an hour larger

A _______ lunar

eclipse occurs

when only part of

How to draw a lunar eclipse:

1) On a piece of paper, draw a Sun on the far left, the Moon on the far right, and the Earth between the two. All bodies need to be drawn in a straight line.
