Children start out as natural scientists, eager to look into the world around them. Helping them enjoy
science can be easy; there's no need for a lot of scientific terms or expensive lab equipment. You only
have to share your children's curiosity. Firstly, listen to their questions. I once visited a classroom of
seven-year-olds to talk about science as a job. The children asked me 'textbook questions' about
schooling, salary and whether I liked my job. When I finished answering, we sat facing one another in
silence. Finally I said, 'Now that we've finished with your lists, do you have questions of your own about
science?'?
After a long pause, a boy raised 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 set 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, s typically wait only one second or less for an answer, no time for a child to think. When
s increase their 'wait time' to three seconds or more, children give more logical, complete and
creative answers.
Thirdly, watch your language. Once you have a child involved in a science discussion, don't jump in
with 'That's right' or 'Very good'. These words work well when it comes to encouraging good behavior.
But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying, 'That's interesting' or 'I'd never thought of it that way before', or coming up with more
questions or ideas.?
Never push a child to 'Think'. It doesn't make sense, children are always thinking, without your
telling them to. What's more, this can turn a conversation into a performance. The child will try to find
the answer you want, in as few words as possible, so that he will be a smaller target for your
disagreement.?
Lastly, show; don't tell. Real-life impressions of nature are far more impressive than any lesson
children can learn from a book or a television program. Let children look at their fingertips through a
magnifying glass(放大镜), and they'll understand why you want them to wash before dinner. Rather than saying that water evaporates (蒸发), set a pot of water to boil and let them watch the water level drop.
