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….

When I was in the sixth grade, one day my teacher asked our class to think about the question “What does ‘doing the right thing’ mean to you?” over the weekend. We could talk to our parents or anyone else we thought might have a good answer.  1  Monday, we were to hand in an essay（论文） on it, and be prepared to live up to our  2 .        
The entire weekend, I was trying to  3  something that would impress my teacher and be easy to live by. I talked to my parents, called my grandmother and asked my neighbor. Everyone had good answers, but I didn’t feel like I could live up to them.
On Sunday afternoon, my parents said they were going to my Aunt Cindy’s house. That usually 4  that I would have to entertain my four-year-old cousin Andrea  5  my parents visited. I found a Disney movie for Andrea, and then I sat down and started to write my essay. It was due（到期的）the next morning and this was my last  6  .
Soon I felt a pair of eyes on me. It was Andrea.  “What are you doing?” Andrea asked. “I have to write an essay about what ‘doing the right thing’ means to me.” I answered. Andrea laughed. Could this smart four-year-old 7 know the answer?  “That’s easy,” she said. “Doing the right thing means being nice to your family and friends. Never lie. Eat lots of fruits and vegetables. Take a bath when you’re 8 . And never put rocks in your mouth.”
I stared with great  9  at my little cousin. Then I jumped up and gave her the biggest hug. Not only had Andrea answered a very tough question for me, but I could easily live by  10  of her answers. All I had to do was to be nice, not to lie, to keep myself clean and healthy, and never put rocks in my mouth. So when I wrote my essay, I  11  the story about Andrea and how she had answered my question.
Two weeks later, my teacher returned everyone’s essays. I  12  an A+ along with a little note my teacher had written at the top: “Always do the right thing and give Andrea an A+, too!”
