Children are natural scientists, very interested in the world around them. Helping them enjoy science can be easy; there’s no need for a lot of scientific terms（科学术语）or modern labs. You only have to share your children’s interests.

　 Firstly, listen to their questions. I once visited a classroom of seven-year-old children to talk about science as a job. The children asked me “textbook questions” about schooling, the money I got and whether I liked my job. When I finished answering, we sat facing each other silently. Finally I said, “Now that we’ve finished with your lists, do you have questions of your own about science?”

After a long wait, a boy put up his hand, “Have you ever seen a grasshopper(蚱蜢) eat? When I try eating leaves like that, I get a stomachache. Why?” This began a lot of questions that lasted nearly two hours.

Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, many teachers usually wait only one second or less for an answer, no time for a child to think. When teachers increase their “wait time” to three seconds or more, children give better answers.

Thirdly, watch your language. When the child is having a science discussion, don’t jump in with “That’s right” or “Very good”. These words work well when it comes to encouraging a child to help others. But in talking about science, these words make a child think that the discussion is over. Instead, keep things going by saying, “That’s interesting” or “I’ve never thought of it that way before”, or coming up with more questions or ideas.

Lastly, show; don’t tell. Let children look at their hands through a microscope（显微镜）, and they’ll understand why you want them to wash before dinner….

I was on the escalator in a market. There was an old man who was about five or six people in the front of me. People behind him were all in a hurry and saw him as a rock. The old man knew these clearly and tried hard to step aside.

I remember…Sometimes when walking or driving behind an older person, I’ve gotten impatient and upset.

“I’m sorry. Please forgive me!” said the old man, “I don’t mean to hold you up.” He then tried his best to get off the escalator.

I suddenly saw this in a whole new light. I felt sick to my stomach. The old man was apologizing to everyone, when we should have helped him to calm his fears.

One by one, people went around him quickly.By the time I got to him, I asked,“Sir, can I help you?”

The man thought for a while, then said,“Well, yes, thank you!”

I placed my hand under his left arm and walked away from the rush of people quickly.

“So what are you shopping for, sir?”

“Oh, today is Mother’s Day. I want to buysomething for my neighbor. She’s a single mother and she is always so nice to me.” he said, stopping suddenly as he searched his pocket.

“Oh, it’s here! I always carry them with me,” he said. Then he took out some business cards and handed me one which read:

“John Smith.

Friend to all…enemy to no one!

I said a prayer today and you were the answer.

Thank you!”

“That’s for you,” he said. “Thanks for stopping to help an old man.”
