1. Bellringer: Put the phases of the moon in orders starting with new moon. Try it without your notes!

2. Eclipses
Study Pack #8

3. Today’s Goals!  I can explain what causes an eclipse.
I can compare solar and lunar eclipses.

4. Eclipses
The sun, moon, and Earth do not usually line up in a straight line
If this occurs a shadow can fall on the moon or Earth
Most months the moon revolves around Earth without moving into Earth’s shadow or the moon’s shadow hitting Earth

5. Eclipses
When the moon’s shadow hits Earth or Earth’s shadow hits the moon, an eclipse occurs
There are two types of eclipses
Solar “sun”
Lunar “moon”

6. Solar Eclipses Happens during a new moon
The moon passes between the sun and Earth
The moon’s shadow hits Earth

7. Solar Eclipse
The darkest part of the moon’s shadow is called the umbra
From this point the sun is completely blocked by the moon
People on Earth experience total solar eclipse
The sky is dark and you can see the stars!

8. Total Solar Eclipse

9. Solar Eclipse
The larger part of the moon’s shadow that is less dark is the penumbra
People on Earth see a partial solar eclipse
It’s never safe to look directly at a solar eclipse!

10. Lunar Eclipse Occurs at a full moon
The Earth is directly between the sun and moon
The Earth blocks sunlight from reaching the moon
