  1. Moon Phases

  2. -The sun always touches half of the moon. -The Moon revolves around the Earth. -During each revolution we see different portions of the lighted half of the moon. http://www.nasm.si.edu/apollo30th/moontheater/phasepage2.html

  3. The revolution of the Moon around the Earth makes the Moon seem like it is changing shape in the sky.  http://btc.montana.edu/ceres/html/birthdayphases.htm

  4. -Humans see the moon at different angles every night.  -At each different angle we see more or less of the lighted half of the moon. -These are called "phases" of the Moon.

  7. New Moon -The Sun, Earth, and Moon are almost in a straight line. The Moon is between the Sun and the Earth. -The lighted side of the Moon faces the sun, not the Earth.  -We see the part of the moon that is NOT lighted, so we see almost no moon.
