The document discusses the phases of the moon over a four week lunar cycle. It explains that the moon does not produce its own light, but rather reflects sunlight. The phase we see from Earth depends on the relative positions of the Earth, moon, and sun. As the moon orbits Earth, its illuminated portion waxes from a new moon to a full moon, then wanes back to a new moon again. The phases include the new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent.

2. Objective: Objects in the sky have a regular and predictable pattern Students know the way in which the moon’s appearance changes during the four week lunar cycle. California Science Standard 4B

3. Unlike the sun, the moon does not give off its own light. Instead it reflects the sun’s light .

4. Because of the orbit we do not always see the full moon.

5. The phase that we see depends on the position of the Earth, moon, and sun .

6. It is called waxing when the reflecting light is growing toward the full moon.

7. It is called waning when the reflecting light is shrinking to the new moon.

8. The moon, sun, and Earth are lined up Sun’s light reflects off the side of the moon facing it. The moon appears dark from the Earth. The New Moon

9. Waxing Crescent It is between the new moon and first quarter A small slither of brightness on the right Dark part is most visible to Earth

10. First Quarter Moon Moon is to the left of Earth and sun Half of the moon is visible to Earth Half light; half dark

11. Waxing Gibbons Stage between first quarter and full moon Most of the bright side is visible

12. We see a full moon when the sun, moon and Earth are lined up. With the side of the moon facing the Earth illuminated. Full Moon

13. After the full moon The right side appears dark or invisible Opposite of waxing gibbous

14. Moon is to the right of the Earth and sun It is the opposite of the first quarter moon Appears to be a half moon

15. Waning Crescent Occurs between the last crescent and the new moon A crescent of the bright side shows on the left edge The rest of the moon facing Earth is on the “dark” side
