Part One: Situation Import

On a dark night, there is a bright moon in the sky. Is the shape of the moon we see the same every night?

During the month of January, it keeps repeating the circle and vacancy, but the position of the vacancy is sometimes on the left and sometimes on the right.

The moon will appear in various shapes during the waxing and waning process. This is what we are going to talk about in this lesson: "Changes of Moon Phases". Let's enter the new lesson together!

Moon phase changes PPT, part 2 content: new lesson explanation

The various shapes that appear during the waxing and waning process of the moon are called moon phases.

The moon itself does not emit light and is not transparent. The sun illuminates one side of the moon. Because moonlight reflects sunlight, no matter where it shines relative to the earth, the side facing the sun is always bright and the side facing away from the sun is dark.

Sort the moon phases:

From new moon to full moon and back to new moon, it is a cycle of moon phase changes. This cycle lasts on average 29.53 days and is called the synodic month. The new moon of each month is the first day of the lunar month, which is the fifteenth or sixteenth day of the month.

The moon phases change, and the changes are regular. In the first half of the moon, the area of ​​the bright side of the moon that people see gradually becomes larger, until the full moon, with the bright side on the right; in the second half of the month, the area of ​​the bright side of the moon that people see gradually becomes smaller, until the new moon, with the bright side on the left .

Simulate moon phase changes

The moon is a non-luminous, opaque sphere, and the moonlight we see is the light it reflects from the sun. The moon phase is actually the part of the moon illuminated by the sun that people see from the earth. Due to different viewing angles, the size and direction of the bright side of the moon seen are different. We can do a simulation experiment to observe.

experiment procedure:

1. Paste a sun on the wall at one end of the classroom or an open space, and draw two circles in the middle of the space. Several students stood on a small circle to represent observers on the earth; one student held up a half-painted leather ball to represent the moon and rotated it around the large circle to represent the moon's movement around the earth for one month.

2. Let the bright side of the "moon" always face the "sun", which means that only half of the moon can be illuminated by the sun. When the "moon" moves to positions 1 to 8 respectively, draw the "moon phases" we observe.

Observe the moon phases during the day

To observe the moon phases during the day, we need to pay attention to:

1. Prepare two pieces of recording paper, draw 15 circles of the same size, and mark the direction.

2. Observe in the evening after school in the afternoon and in the early morning before school in the morning, and record the moon phase in the sky, the old calendar time of the moon phase, the position of the moon phase, and the position of the sun.

Moon Phases Song

The new moon on the first day of the lunar month cannot be seen because it is trapped between the sun and the earth.

On the seventh and eighth day of the lunar month, the first quarter moon appears, and the half-full moon faces west.

The full moon occurs on the 15th and sixteenth day of the month, with the Earth and the Sun holding the Moon on one side.

On the twenty-second and third quarter of the moon, the moon faces east at midnight.

Memorize formula:

Up, up, west and west, down, down, east and west

The first quarter moon occurs in the first half of the night during the first half of the lunar month, with the moon facing west in the western half of the sky;

The last quarter moon occurs in the second half of the second half of the lunar month, with the moon facing east in the eastern half of the sky.

Moon phase changes PPT, part 4 content: Class summary

The various shapes that appear during the moon's waxing and waning changes are called moon phases.

How the moon phases change over the course of a month:

The first half of the moon changes from waning to round, and the second half of the moon changes from round to waning.
