The Earth travels through its orbit around the sun at about 108,000 mph.
How fast does the Earth travel through its orbit around the sun? (how many miles per hour?)
The time it takes for the Moon to spin on its axis is about EQUAL to the time it takes the moon to travel around the Earth.
How long does it take for the moon to spin on its axis when compared to the time it takes for the moon to travel around the Earth?
False: An eclipse happens when a shadow is cast on some other body. (like the moon)
True or False: An eclipse happens when a shadow is cast on the sun.

The moon has a side that we never see, which should be called the 'far side'.
Does the moon have a 'dark side' or a 'far side'?
False; when we see a full moon, we are only seeing 50%, or half of the moon lit up by the sun.
We are seeing 100% of the moon's surface lit up by the sun when we look at a full moon. (true or false)
Look at the north axis; the left is closer to the sun so it would be summer, the bottom would be fall, the right would be winter since the north axis is pointing away from the sun and the top would be spring. *Tip* Always find summer and winter first!!
Can you label this diagram with the seasons for the northern hemisphere? (summer, fall, winter, spring)
When the Earth casts a shadow on the moon, it is a lunar eclipse. (The moon has a shadow. Moon = lunar)
When the Earth casts a shadow on the moon, is it a solar or lunar eclipse?
When the moon casts a shadow on the Earth, interfering with the sun it is a solar eclipse. (Shadow on earth = solar)
When the moon casts a shadow on the Earth, interfering with the sun, is it a lunar or solar eclipse?
Sun is at the bottom, so: bottom = new moon, to the right is the waxing crescent, then the 1st quarter. At the one o'clock part is the waxing gibbous then the full moon is at the top. To the left of the full moon is the waning gibbous, then the 3rd quarter moon. At the seven o'clock part is the waning crescent.
Can you label the 8 moon phases? (1st quarter, full moon, new moon, 3rd quarter, waning crescent, waning gibbous, waxing crescent, waxing gibbous) *Make sure you look for the sun!! In THIS case the sun is at the BOTTOM of the picture.
