Solar & LunarEclipses
• I can explain what causes a lunar eclipse.• I can make a diagram of what a lunar eclipse looks like.• I can persevere in order to understand a natural phenomenon – one that is happening this weekend!
What we will learn…
Orbit
Rotation
Lunar Eclipse
Key Terms
• Eclipses happen because the Earth, Sun and Moon occasionally line up so that there is a shadow created.
• This usually happens every year, but you must be in the right part of the Earth to be able to see it!
How often do eclipses happen?
• When the Moon’s shadow covers part of the Earth, there is a solar eclipse.
• A solar eclipse can only happen at a New Moon.
Solar Eclipse
• You will only see the solar eclipse if you are located in the part of the world where the umbra or penumbra falls.
• In the umbra area, you’ll see a full eclipse• In the penumbra area, you’ll see a partial eclipse
Why don’t we always see it?
It isn’t safe to STARE! (but here we can!)
The Moon’s shadow…
• When the moon moves into the shadow of the Earth, some or the entire moon appears dark.
• Since the Earth’s atmosphere filters some of the sun’s light before it reaches the surface, a lunar eclipse often appears red!
Lunar Eclipse
• You will only see the lunar eclipse if you are located in the part of the world where the umbra or penumbra falls.
• In the umbra area, you’ll see a full eclipse• In the penumbra area, you’ll see a partial eclipse
