Private Universe

1. How the phases of the moon occur?
The Earth orbits around the Moon so we only see pieces of the moon at a time. Shadow?

Moon never changes shape. It is only the way the sun reflects the moon.


2. What causes the seasons?
The orbit of the Earth with the Sun causes a change in temperature. When we are closer to the sun it's hotter and further is cooler.

The Earth is tilted. And depending on the tilt of the moon and where the sun is, the seasons change.

3. What causes a lunar eclipse?
When the moon orbits and the Earth orbits at a particular location.

Formative

Galeleo (sp?)

helio-centric (sun in the center)

geo-centric (Earth in the center)

The sun does not move. North star= big bear, always tilt pointing towards the north star

Earth orbits around the Sun= 1 year

Northern Hemisphere is titled toward the Sun= summer.

Solar Eclipse: can't see the Sun
Lunar Eclipse: can't see the moon!
Blue Moon: 2 full moons in one month
Waxing: getting bigger
Wayning: getting smaller
The moon is not in the plane of the equip tic
The moon dives in and out of its own orbit
