The moon observation is the most amusing thing about my class. I draw the moon every day on paper. I believe that the different kind of shape the moon every day. I have always wondered why we can always see the same side of the moon from the earth. Then I got the answer, and the moon always showed us the same face, because the gravity of the earth has slowed the rotation of the moon. After finding the moon, write down the time in the observation log, outline the appearance of the moon, and describe its position in the sky. Go back to the same time the next night; you will find that the moon is higher in the sky, easier to see To. Observe and paint the picture every night. But sometimes it will miss a few nights due to bad weather or rainy days, but they have not given up the habit of observing the moon. In other words, the moon rotates every day to compensate for the angle it sweeps in Earth's orbit. But I think this homework is to open my mind and let me think more about art. Sometimes I just watch the moon, but I don't want anything; sometimes I will focus on the moon and think about many things. If I look at the shape of the moon very carefully, I will find some shapes on the moon that look like humans or animals. In addition, I think that drawing the moon is an elegant piece of art. You will like to record slowly and love this thing to the end.
