Ingeniously remembering the law of the moon's phase change
He could use the moon phase formula to remember the changes of the moon phase,"up, west, down, east." Its meaning was: the first quarter moon appeared in the first half of the lunar month, facing west, located in the western half of the sky (the concave side facing east); the last quarter moon appeared in the second half of the lunar month, facing east (the concave side facing west), located in the eastern half of the sky. In addition, the moon's phase changes in a lunar month were roughly as follows: from the first day to the fifteenth day, the new moon, the crescent moon, the first quarter moon, the full moon, and the full moon, the "bright side" gradually increased; from the fifteenth day to the thirtieth day, the full moon, the weak moon, the last quarter moon, the waning moon, and the new moon, the "bright side" gradually decreased. It could also be understood like this: on the first day of the first month, the moon and the sun rose and set at the same time; on the first quarter of the first month (the seventh and eighth day of the first month), the moon rose at noon and disappeared at midnight; on the fifteenth and sixteenth month of the first month (the fifteenth and sixteenth month), the moon rose at noon and disappeared at sunrise; on the last quarter of the first month (the twenty-second and twenty-third month), the moon rose at midnight and disappeared at noon.

The Law of Moon Phase Changes
The law of the change of the moon phase children's song: the first day of the new moon is invisible, only because it is trapped in the sun and the earth; On the seventh day of the eighth month, half of the full moon faces west; The full moon appears in the fifteenth and fifteenth days, and the earth carries the sun and moon on its shoulder; Twenty-two or three last quarter moon, the moon faces east in the middle of the night. There was also the formula "Up, Up, West, Down, Down, East", which meant that the first quarter moon appeared in the first half of the lunar month in the middle of the night. The moon faced west and was located in the western half of the sky (the concave side faced east). The last quarter moon appeared in the second half of the lunar month in the middle of the night. The moon faced east (the concave side faced west) and was located in the eastern half of the sky. The novel New Moon is equally exciting. Everyone is welcome to click and read it!

Moon phase change animation
The animated demonstration of the changes in the moon phase helped to better understand the changes in the moon phase. In the moon phase animation, a fixed space background would usually be displayed. The moon would move in the background as the date changed, and bright colors would be used to represent different moon phase states. For example, a full circle represented a full moon, and a full black represented a new moon. The moon phase changes can be divided into eight different states, including the new moon.(The sun shines on the dark side of the moon, and the moon is completely unlit and appears black), Emei Moon (the moon begins to be illuminated by the sun's rays, and the moon appears a slender arc), Second, Third, Fourth, First Quarter Moon (the left edge of the moon is strongly illuminated, and the moon moves the fastest during the change of the moon's phase), Reunion Moon (also known as the full moon, and the moon appears to be completely round), and Last Quarter Moon (the right hemisphere is illuminated by the sun's rays). Every month, there were four distinct changes in the moon's phase: the moon was completely covered by the sun at the new moon, and the moon could not be seen. At the first quarter of the moon, only half of the moon was illuminated by the sun, forming a semicircle. At the full moon, the moon was completely illuminated by the sun, forming a circle. At the last quarter of the moon, only half of the moon was illuminated by the sun, forming a reverse semicircle. In addition, the change of the moon's phase was affected by the position of the Earth, the Sun, and the Moon. It was also affected by the shape and surface of the moon itself. For example, the pits on the surface of the moon would make the moon appear irregular. Observing in the northern hemisphere, the moon was below the sun at the new moon, west of the sun at the first quarter and full moon, and east of the sun at the last quarter. Observing in the southern hemisphere, the position and appearance were opposite. The novel New Moon is equally exciting. Everyone is welcome to click and read it!
The fundamental reason for the change in the moon's phase is
The fundamental reason for the change of the moon's phase was that the relative positions of the three celestial bodies, the sun, the moon, and the earth, were constantly changing regularly. Since the moon itself did not emit light, it mainly relied on reflecting sunlight to shine. When the relative positions of the three were different, from the perspective of an observer on Earth, the part of the moon illuminated by the sun would appear in various shapes, resulting in changes in the moon's phase.

What is the cause of the change in the moon's phase?
The changes in the moon's phase were caused by the changes in the positions of the three celestial bodies, the sun, the moon, and the earth. The moon itself did not emit light. It mainly relied on reflecting sunlight to shine. Its relative position to the sun was different (the difference in the ecliptic), so it would appear in various shapes. As the moon moved from west to east in the starry sky every day, its shape also changed constantly. This was the change of the moon's phase. For example, when the moon was located between the Earth and the Sun, and the difference in the ecliptic of the sun and moon was 0°, the dark side faced the Earth and appeared almost at the same time as the Sun. This was the New Moon (the first day of the first lunar month). At the 15th and 16th of the lunar calendar, the moon turned to the other side of the earth. The earth was between the sun and the moon, and the half of the moon illuminated by the sun was facing the earth, which was the full moon. The novel New Moon is equally exciting.

Moon phase change map and moon phase name fill in the blanks
The relationship between the moon phase change map and the moon phase name
The changes of the moon were generally divided into the stages of the new moon, crescent moon, first quarter moon, full moon, moon, waning moon, last quarter moon, waning moon, and so on. In the Moon Phase Change Map, each phase corresponded to a specific moon phase name. During the new moon, the moon moved between the earth and the sun, with its dark side facing the earth and rising and setting with the sun. This stage was at the starting position in the lunar phase change map, and the moon could not be seen. The crescent moon appeared after the new moon. Its shape was curved like an eyebrow, and the protruding part of the moon was facing west in an inverted C shape. It was the transition form of the new moon to the upper and lower quarter moon. The first quarter moon appeared around the seventh day of the lunar calendar. From the northern hemisphere, the right half of the moon was illuminated, forming a semicircle. At this time, the line connecting the sun and the earth was vertical to the line connecting the earth and the moon. It was located in a specific transition position in the moon phase change map. The full moon was between the first crescent moon and the full moon, and the illuminated part of the moon gradually increased. The full moon (Wang) appeared at the 15th and 16th of the lunar calendar. The earth was located between the sun and the moon. The side of the moon facing the earth would be illuminated. The round moon could be seen all night. In the lunar phase change chart, it was the phase where the moon was the most illuminated. Fortunately, after the full moon, the illuminated part of the moon gradually decreased. The last quarter of the moon appeared around the 22nd of the lunar calendar. The left half of the moon was illuminated from the northern hemisphere, almost in the shape of a semicircle. The waning moon appeared at the end of the lunar calendar. The protruding part of the moon faced east, like the letter "C." It was the transition from the last quarter of the moon to the new moon. It was close to the beginning of the next cycle in the lunar phase change map. The novel New Moon is equally exciting. Everyone is welcome to click and read it!
