What do you know about the moon?
How big is the moon?
How far away is the moon?
How are craters formed?
How do you think lunar craters are formed?
• How does height affect crater size?• How does mass of impactor affect crater
size?• How does angle of impact affect crater size?• How does the material of the surface affect
crater size?
Impact Craters
• What do you measure when you measure craters?
• How do you measure the area of an irregular shape?
Measuring Craters
How can you measure the scale of a lunar image?
Measuring Craters From a Distance
700 m (500 pixels)
Suppose that over a period of 100,000 years, four asteroids struck the lunar surface.
What would be the probability that they would strike an already-cratered area, or the lunar mare, where there are few craters?
Crater Probability
What can we learn from creating our own lunar impacts?
LCROSS
Exploring the Moon
Moon Math Supplemental GuideStudents will:
1) approximate the area and volume of a classroom-made crater, 2) calculate and compare thescale of lunar craters to classroom craters, and 3) observe how the size, mass, and angle of impact of a projectile affect the area andvolume of a crater.

The Milky Way . . . how big is big?
If our entire solar system could be shrunk down to the size of a quarter, the Milky Way Galaxy, which is approximately 10,000 light- years in width, would be the width of the continental United States!
