Why does the moon look bright sometimes?
It reflects light from the sun.
A group of students look up at the stars...
A
Why does the Sun appear to be the largest star?
It is the closest star to Earth.
On December 21st, the Earth's revolution and tilt causes the Northern Hemisphere to get the (most/ least) amount of daylight for the whole year.
least
Why do we have different phases of the moon?
The moon is orbiting (revolving) around Earth, which changes the way the sunlight lights up the moon.
Which region of Arizona gets the most amount of rainfall, and which region gets the least? (last slide of slideshow)
Central= Most Rainfall
Southwest= Least Rainfall
Why can't we see other stars (besides the sun) during the day?
The light from the sun is much stronger, since it is the closest star.
What causes day and night?
Earth's Rotation!
Why do solar and lunar eclipses occur?
The moon revolves around the Earth, which can sometimes cause eclipses.
The student only sees the constellation Sagittarius at night because of what Earth pattern?
Earth's Rotation
What happens to shadows from morning to afternoon? Why?
They change in length and direction. They change because Earth is rotating!
What causes seasons?
Earth's revolution and tilt!
What direction does Earth's gravitational force act on objects?
The center of the Earth!
The student only sees the constellation Sagittarius at some points of the year because of what pattern?
Earth's Revolution around the sun changes what stars we see (since we are moving around in space)
Why does the sun appear to be moving across our sky during the day?
Because Earth is rotating!
We wouldn't have different seasons: weather would be mostly mild all year (like fall or spring weather)
If you were to drop a bowling ball and a tennis ball off of the same height in a vacuum (NO AIR), which one reaches the ground first?
They both reach at the same time!

How do scientists know the Sun is a Star?
The Sun is a star since it is a large ball of gas that is made of plasma and produces light.
What causes the number of daylight hours to change throughout the year? (Example: most hours of daylight is on June 21st)
The Earth's tilt and revolution around the Sun cause the number of daylight hours to change.
