This is my science artifact on Astronomy 6.E.1.1. There are also some educational videos if you do not like to read.

Phases of the Moon

The names of the moon in the phases of the moon are new moon, waxing crescent, 1st quarter, waxing gibbous, full moon, wanning gibbous, 3rd quarter and wanning crescent.
The difference between wanning and waxing is that waxing means illumination increases and wanning means illumination decreases. Then the difference between a crescent and gibbous is a crescent is LESS than half while gibbous is MORE than half.

The two types of tides are spring tides and neap tides.

You may be wondering what Semidiurnal and Diurnal mean, well I'll tell you the difference between those two are well in a semidiurnal there are two high tides and two low tides while in a diurnal there are only one high tide and one tide. Then you may also be thinking what's the difference between a neap tide and a spring tide and how do I tell those two apart. Well I'll tell you. Just one little thing before we begin if you think that spring tides have something to do with the season spring you are totally wrong spring tides are not one bit related to the season spring. Anyway the difference is that spring tides are strong tides, hey occur when the earth, sun, and the moon are in a line. They appear during the full and new moons. They are really weak tides they happen when the moon and sun are perpendicular. Also in a spring tide the moon and the sun's gravitational combine to create a particularly strong tide in a neap tide the gravitational forces of the moon and the sun are perpendicular to one another. The sun and moon's gravity cancel each other out.

There are two types of eclipses and they are the solar eclipse and the lunar eclipse the difference of those two are that A lunar eclipse occurs when the Earth passes between the moon and the Sun and a solar eclipse occurs when the moon passes between the Earth and the Sun. The difference between a penumbra and an umbra is that an umbra is a full shadow and a penumbra is a partial shadow.
What's the difference between a solar and lunar eclipse?


Let me tell you about rotation and revolution. Rotation is when the earth rotates on its axis. Also did you know it take one day for the world to rotate on its axis. A day on earth would depend on which side you are in and if the earth's side is facing toward the sun. The earth also revolves around, it takes the earth about an year to do it. Also did you know the earth is closest to the sun around Jan 3 and farthest away from the sun in July 4. The earth does not orbit around the sun in a perfect circle it orbits around in an ellipse. Did you know how we have seasons its because of the earth's tilting.

Why do we have seasons?
