(new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, waning crescent) 2. How many weeks for a moon to change from one phase to another? (4 weeks- four weeks) 3. What are the four main phases of the moon? (New moon, first quarter, full moon and last quarter) 4. How many days does it take for the moon to complete one phase? (29 ½ days) 5. Does the moon shine on its own light? (The moon does not have a light of its own. It only reflect its light from the sun.) IV. Match the items in Column A with the items in Column B. You may write the letter of the correct answer on a separate sheet of paper. Column A Column B _________1. The phase seen when the moon is between the Sun and Earth a. month _________2.
