"Why do the moon phases change?" Sun, Earth, and Moon System PPT Courseware

In addition to the moon on the 15th and 16th days of each month in the lunar calendar, have you seen the moon in other shapes?

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

Analysis of causes of moon phases

The moon is a non-luminous, opaque sphere. Moonlight is the light of the sun reflected by the moon.

Only half of the moon is illuminated by sunlight, the half facing the sun is bright, and the half facing away from the sun is dark. The size of the moon's bright side changes when viewed from different angles.

Moon phase simulation experiment

As the moon orbits the earth counterclockwise, its position relative to the earth is constantly changing. At different positions and angles, how will the size and direction of the bright side of the moon we see change?

Let's do a simulation experiment to see it.

Questions that can be explored in the future:

1. What is the pattern of the position of the moon in the sky?

2. When does the moon rise and set, and what are the rules?

3.………….

There are still many questions about the moon waiting for us to observe and discover. Let us start by observing and recording the moon phase changes for a month!

Observe and record the moon phases for a month

When to observe and record?

Now is the first half of the lunar month. It is recommended to observe and record after evening. It is best to set the time for observation every day.

If you cannot find the moon phase in the evening, please look for it again the next morning.
