How much larger is the Sun than the Earth?
The Sun is smaller than the Earth.
The Sun is approximately 110 times bigger than the Earth.
They are the same size.
The Sun is approximately 20 times bigger than Earth.
The Sun looks small in the sky because...
It is small compared to Earth
It is 1 Astronomical Unit (93 million miles) away.
It is not very bright.
Earth's moon reflects the light away from Earth.
How do you make a scale model? Select all that apply.
If it is large objects like the solar system, reduce all objects by a common factor (dividing by a number).
Scale models do not require reducing (dividing by a number) or enlarging (multiplying by a number).
My seventh grade math teacher taught me this. I know I should select this answer because they will be very upset if they know I forgot.
If it is small objects like a cell, enlarge all objects by a common factor (multiplying by a number).

Lunar eclipses can only occur when it is a ___ moon.

Why do we see lunar eclipses more often than solar eclipses?
Lunar eclipses are NOT more common than solar eclipses.
The Earth is 4 times larger than the moon and easily casts a shadow.
The umbra (shadow) is very large so a lot of people on Earth can see it.
The moon's orbit around Earth is short, so it aligns with the Earth and Sun often.
In your own words, explain how a LUNAR eclipse happens.
