16th: In the sky

You can always see the sky above you. When it's fine in the day, you can see blue sky or white and gray clouds. When it's fine and rainy, you can see a rainbow sometimes. At night the sky gets dark.  You can see the moon. The moon changes the shapes day by day. You can also see stars which are far out in space.

The sun shines in the sky and gives our planet light. It is so hot that it makes our planet warm. Thanks for that, we can live on the earth. The earth always turns. When your place turns toward the sun, it is day. On the other hand, when your place turns away from the sun, it is the night. Then the earth turns and it is day again. Because it's dark at night, people make light with electricity or candles.

There are more things about the sky or planet in the book. Though I know what is said there, but reading this book was interesting.
