Astronomy explain by Cavins Dad.......

Q. Why does the sun set?
A. It’s because hot air rises. The sun’s hot in the middle of the day, so it rises high in the sky. In the evening then, it cools down and sets.
Q. Why does it go from east to west?
A. Solar wind.

Q. Why does the sky turn red as the sun sets?
A. That’s all the oxygen in the atmosphere catching fire.
Q. Where does the sun go when it sets?
A. The sun sets in the west. In Arizona actually, near Flagstaff. That’s why the rocks there are so red.
Q. Don’t the people get burned up?
A. No, the sun goes out as it sets. That’s why it’s dark at night.
Q. Doesn’t the sun crush the whole state as it lands?
A. Ha ha, of course not. Hold a quarter up. See, the sun’s just about the same size.
Q. I thought I read that the sun was really big.
A. You can’t believe everything you read, I’m afraid.

I just love Budda stories for children.  They are simple. An kind.  esp.  If they are about Turtles. Here's one enjoy.

The Soft-shell Turtle Who Cures Ailments

 Once upon a time there was a couple whose surname was Zhang. They liked eating soft-shell turtle very much. One day they bought a huge soft-shell turtle and gave it to the young maid called Sia, 

"Sia! Kill this soft-shell turtle. This time we want to eat a barbecued one, pay attention todo your best!"  Sia had never been fond of killing. However, it was hard for her not to obey the command of the master. Therefore having no way out, she started to sharpen the knife in the kitchen. The knife became sharper and sharper. Sia gazed at the soft-shell turtle. She saw it looking at her with its eyes begging her not to kill.  Suddenly Sia felt that she did not have the heart to kill it. Therefore she secretly took the soft-shell turtle and set it free in the river. Then she told the master a lie of good-will,  "I'm sorry, it was me who didn't look well after the soft-shell turtle and now it is missing. Please forgive me."  Hearing that the master was outraged,  "How could you be so careless! Where were your eyes? How could you lose such a big soft-shell turtle? Iam really disappointed! Without any cause you let us lose a beautifulmeal! Alas!"  Not long after suddenly Ape suddenly fell severely ill and it seemed that she was dying. Mr. and Mrs Zhang saw no sign of her recovery, so they called people to take her home. However, those people threw her on the river bank near her home and went off. 

At midnight, a big soft-shell turtle suddenly emerged from the water, carrying wet mud, the sort-shell covered Sias body with the mud. Originally Sia had a temperature all over her body. But then she felt her body become so much cooler and she recovered in no time. When Sia went back to her master's place, everyone was so surprised that no one could say a word.  "What was the matter?"

Sia told the story of how the soft-shell turtle helped her to cure the disease. The master only half-believed her so they went to look for the soft-shell turtle. Consequently they discovered that it was the one they had lost. The whole family was deeply moved by this incident. The couple hugged Sia and said, "Fortunately you set free the soft-shell turtle so that we will not continue to make mistakes. Sia, from now on we swear we will not eat soft-shell turtles any more."
