Children start out as       scientists, eager to look into the world around them.      them enjoy science can be    ; there's no need for scientific terms or expensive lab equipment. You only have to share your children's interests.
Firstly, listen to their questions. I once     a classroom of seven-year-olds to talk about science as a job. The children asked me "textbook questions" about schooling, salary and my job. When I        answering, I said, "     we're finished with your lists, do you have questions of your own about science ?" After a long  , a boy     his hand, "Have you ever seen a grasshopper（蚱蜢）    ？When I try eating leaves like that, I get a stomachache. Why ?" This began a set of questions that     nearly two hours.
Secondly, give them time to think. After asking a question, teachers often wait only one    or less for an answer, no time for a child to think. When teachers    their "wait time" to three seconds or more, children usually give better answers.
Thirdly, watch your language. When children are having a science discussion, don't jump in with "That's right" or "Very good" because these     may make the children think that discussion is over.   , keep things going by saying, "I'd never thought of it that way before", or coming up with more questions or ideas.
Never     a child to "think". It doesn't make sense, because children are always thinking without your telling them to. What's more, this can turn a conversation     a performance.
    , show in stead of telling. Let children look at their fingers through a magnifying glass（放大镜）,     they'll understand why you want them to     before dinner. Rather than say that water evaporates（蒸发）, set a pot of water to boil and let them watch the water level    .
