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….

As a girl, I've spent a great deal of my time on earth concerned about my weight. So I do know something about exercise. Let me tell you about the calorie-burning activities I've tried or will try.
Salsa (萨尔萨舞)
I try to maintain my weight through dancing. Dancing improves my coordination and sense of rhythm in addition to burning calories. I'm personally interested in salsa, which I find sexy and expressive(有表现力的). But I have not yet to start classes, because classes are very expensive, and I cannot find a dance partner.
Ping-Pong
Ping-pong is the national sport of China, so how could I know nothing about it?
My father is a ping-pong fan, and a really good player. He's won several informal (非正式的) matches. My relationship with ping-pong has always been on-and-off. I'll get into it for a while, and then lose interest. The reason is because I can’t find a good partner. Some stronger can depress you, while someone weaker (or just as weak) can make the game boring.
Tae Kwon Do （跆拳道）
I've recently decided to try tae kwon do as my regular exercise activity. There’s a story behind this choice: A few weeks ago, I was sitting on a bus, concentrating on a book. Suddenly, the bus became very quiet except for the sound of a woman’s crying. I looked up to see what had happened and overheard whispers that she had just quarreled with a man, and the man slapped(拍打) her face. No one on the bus dared say anything because the man looked really strong. Even now I feel ashamed I was among the silent.
That’s why I've made up my mind to learn something that will help me protect others and myself.
