  1. Warm Up, March 26, 2013 Fact: On earth we only ever see the same side of the moon. In other words, it is phase locked. Question for you: Can/does the moon rotate? Or does it just revolve around earth? Explain your thinking.

  2. It does rotate! • The moon’s rotation is the same length as its revolution around earth. • Try It! • Pick a partner. One of you act as the earth and one act as the moon.

  3. Agenda • Warm Up • Correct HW • 12.4 Notes “The Moon” • Earth’s Moon Investigation Lab • Cool Down

  4. 12.4 The Moon • Galileo invented a telescope like the one below and was the first person to view the moon through it. • He was able to see details of the moon no one had seen before.

  5. Earth’s Moon Facts • Size: 3,476 km in diameter (about the same distance as going from LA to NY) • No atmosphere • No iron core, so no magnetic fields • Temperature range: -180°F to 300°F • No liquid water • Phase Locked: we always see the same side of the moon from earth • About 4.6 billion earth-years old or 4 600 000 000 years. • Largest moon relative to its planet in our solar system • One-sixth of earth’s gravity

  6. The Moon’s Surface • Maria – Latin for “seas”, these are the dark lowland areas, ancient people thought these were oceans. • Highlands – The lighter regions of the moon are the highlands

  7. Craters • The moon has no atmosphere, or layer of gases around it to protect it from meteoroids. • Meteoroids are simply chunks of rock that are moving in space. (Because of Newton’s 1st Law, they keep moving until they hit something – like the moon) • Most craters are found in the highlands and not in maria.

  8. Shooting Stars on Earth • When small meteoroids are on a collision course with earth, they usually burn up in our atmosphere. • We call them “shooting stars” although they are not “stars” at all. • It the meteoroid reaches earth’s surface, we call it a meteorite.

  9. Cool Down • Title: Earth vs Earth’s Moon Double Bubble Map • P. 491 #1a-c, 2a-c, 3a-c • 12.4 Vocabulary Booklet (4 words) • Finish “Earth’s Moon Investigation Lab” • Start “Observations of the Moon Assignment” Homework
