But it Does Move
This is the path an object takes as it travels around another object
Orbit
How does the tilt of the Earth's axis cause the seasons?
One hemisphere is always getting more light than the other.
This is Galileo’s law stating that it takes a pendulum the same time for each swing.
Law of the Pendulum

He saw the circular shadow during a lunar ecplise, and noticed that stars looked different in different parts of the world.
This is the belief or idea that the Sun is the center of the universe and that the Earth and planets revolve around it.
Heliocentrism
This is one complete trip around an object in a circular or nearly circular path.
Revolution
What causes summer in the Northern Hemisphere?
The Northern Hemisphere is tilted toward the Sun.
This states that planets travel faster when closer to the Sun and slower when further away.

The Moon, Mercury, Venus, the Sun, Mars, Jupiter, and Saturn.
This is the belief or idea that the Earth is the center of the universe, and that the sun and planets revolve around it.
Geocentrism
This a complete spin on an axis.
Rotation
When it is winter in the Northern Hemisphere, what season is it in the Southern Hemisphere and why?
This states that planets orbit in elliptical orbits.
Law of Elipses
What two things did Galileo notice that suggested that the Earth revolves around the Sun?
Jupiter had moons, and that the planets did not seem to circle the Earth perfectly.
This is an orbit in an oval shaped manner.
Elliptical
How long does it take for the Earth to orbit the Sun?
365 1/4 Days
When it is summer in the Northern Hemisphere, what season is it in the Southern Hemisphere and why?
Winter, because the Southern Hemisphere is tilted away from the Sun.
This states that the further away a planet is from the Sun, the longer it takes to orbit.
The Law of Harmonies
He suggested the Earth revolved around the Sun using math, but failed to demonstrate it emperically.
Copernicus
1,500 years.
About how fast does the Earth spin?
About 900 miles an hour.
There are only two days a year where the Earth gets equal day and night. What are they?
Spring and Fall Equinox
According to the Law of Harmonies, which planet should orbit the Sun the fastest?
Mercury.
Why does the Bible NOT state that the Sun revolves around the Earth?
Which is correct: Heolicentrism or Geocentrism?
Neither. While the planets do orbit the Sun, the Sun is not the center of the universe; she revolves around Saggitarius A*.
