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….

　　Our guide told 7 all about Sue. He told us to look at her 8 . Sue had 60 of them. They were long and sharp. One tooth looked as 9 as my school ruler. The guide said the dinosaur's teeth showed that she was a meat eater. I'm glad I wasn't around when the dinosaurs were alive. I might have been lunch.

　　As I looked at it, I wondered what the dinosaur had looked 10 when it was alive. No one knows what 11 dinosaurs were, but I pictured it as brownish-grey. I could see it going through the grass and trees searching for food.

　　Suddenly I realized that the skeleton had once belonged (属于) to a 12 animal here on Earth. It made me think about other 13 that had once lived here. Now I 14 why people want to learn about these animals. 15 would be very exciting to find a dinosaur skeleton.
