2. Specific observation methods and content:

(1) Choose a clear night and observe the moon for a month;

(2) Stand facing south and select a reference object at a fixed location;

(3) Observe regularly at sunset in the first half of the month and at sunrise in the second half of the month;

(4) Complete the observation record sheet (Textbook P18);

(5) After observing for a month, study your observation records to see how the observed position and shape of the moon change day by day.

Observation 1:

①Observe the position of the moon at different times of the day, such as 8pm, 10pm, 12pm, 2am, 4pm, and 6am.

Q&A:

①How does the position of the moon change at different times of the day? Why is this happening?

Answer: At different times on the same day, the position of the moon rises in the east and sets in the west! Because the Earth rotates from west to east, the moon appears to rise in the east and set in the west.

Observation 2:

②Observe the position of the moon at the same time on different dates, such as 8 o'clock in the evening or 6 o'clock in the morning every day

Organize observation records:

1. Does the position of the moon in the sky change at the same time on different dates? Why?

Answer: There are changes. The moon's position is moving from west to east. This is caused by the moon's revolution from west to east.

2. Does the shape and direction of the bright part of the moon change on different dates?

Answer: The first half of the moon goes from waning to full, with the bright part facing west; the second half of the moon goes from round to waning, with the bright part facing east.

3. How many days are there between two full moons? What does this mean?

Answer: They are 30 days apart, which means that the moon's revolution period around the earth is 30 days, which is one month.

new moon

On the first day of every month in the lunar calendar, there is no moon visible on the earth, which is called a new moon.

The moon cannot be seen on the 30th day of the lunar calendar, so it can also be called the new moon.

crescent moon

The Emei Moon refers to the Emei-like moon that appears in the western sky on the second and third days of the lunar calendar after the new moon.

First quarter moon

The half moon seen on the seventh and eighth day of the lunar calendar is called the first quarter moon.

The waxing moon appears in the first half of the moon, with the bright side facing west.

1. In fact, each moon phase rises in the east and sets in the west. For example, the first quarter moon rises from the east around 12 noon, but because the sun is too strong at that time, it is impossible for the human eye to distinguish the moon.

2. Why is the moon visible in the first half of the first half of the month but not in the second half of the night? Why is the moon not visible in the first half of the second half of the month but visible in the second half of the night or early in the morning? Why is the moon visible all night only on the 15th and 16th? This is determined by the position of the moon's revolution and the rotation of the earth.

3. The lunar calendar dates were arranged by the working people in ancient my country based on the phases of the moon, and the people relied on it to estimate dates and times.

judge:

1. The phases of the moon are constantly changing. To put it simply, the bright right and dark left are the moon phases at the beginning of the month, and the waning left and waxing right are the moon phases at the end of the month. ( )

2. The moon also has day and night phenomena. The change of the moon phase means the shape of the moon changes. ( )
