Children are natural scientists. They are interested in looking into the world around them. Helping them enjoy science can be easy; there’s no need for a lot of expensive lab tools. You only have to share your children’s curiosity(好奇).

Firstly, listen to their questions. I once visited a classroom of seven-year-old students to talk about working as a scientist. The children asked me questions about schooling and whether I liked my job. When I finished answering, we sat facing one another quietly. Finally I said, “Now that we’ve finished, do you have questions of your own about science?”

After a long pause, a boy put up his hand, “Have you ever seen a grasshopper(蚂蚱) 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 have shown that, after asking a question, adults usually wait only one second or less for an answer, do not leave time for children to think. When adults increase their “wait time” to three seconds or more, children can give more logical(合逻辑的), complete and creative answers.

Thirdly, watch your language. Once you have a child telling his idea 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 mean that discussion is over. Instead, you can say “That’s interesting. ” or “I’d never thought of it that way before. ” or come up with more questions or ideas.

Never push a child to “Think”. 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(目标)for your disagreement.

Lastly, show; don’t tell. Real-life feeling of nature is far more exciting than any lesson children learn from a book. Let children look at their fingertips(指尖) through a magnifying lens(放大镜), and they’ll understand why you want them to wash before dinner.

BALTIMORE. MARYLAND—An old postcard changed the lives of an eleven-year-old boy and a very sick woman. The postcard had a picture of the steamship Titanic. The Titanic was the largest ocean ship in the world. It hit an iceberg（冰山）and sank on April 14. 1912. More than 1,500 of the 2,200 people on the ship were killed.
　　The postcard was passed from one person to another for more than 80 years. Then it appeared at a card show for people who liked to collect postcards. An eleven-year-old boy, Joey Russell, came to the show with his grandfather. His grandfather knew everything about the Titanic and its trip from England to New York. “Let’s buy that postcard.” he told Joey. “It will be important someday.”
　　Two years later, Joey’s grandfather took him on a special trip. They went on a trip to the North Atlantic ocean to watch as workers pulled the Titanic up from the bottom of the ocean. Joey put his special postcard in his bag for the trip. On the ship, Joey met Edith Haisman. This woman was on the Titanic when it sank. She was one of the people who were rescued. Joey pulled the postcard out of his pocket. “Please sign this, Mrs. Haisman.” he said. She was happy to write her name on the back of the postcard.
When Joey got home, he put the postcard away and forgot about it, Then Kate Shelley, one of Joey’s friends, told him that her mother was very sick. She needed an operation, but there was a problem. The operation was very expensive, and the family needed $80, 000 to pay for it. Friends and relatives tried to help. But where could they get so much money?
　　Then when Joey went to see the new movie “Titanic”, he had an idea. “Millions of people are seeing this movie and reading about the Titanic.” Joey thought. He remembered the old postcard with Edith Haisman’s signature on it. “Maybe I can sell it for some money. Then I can help Kate’s mom.”
　　Joey told his mother and father about his idea to help Mrs. Shelley. His parents helped him try to sell the postcard to the person who would pay the most money for it. Joey’s story was on television and in newspapers. Joey and Kate even went to New York to be on a national TV show. After the show, many people called in to offer money for the Titanic card. Someone bought it for $60. 000.
Joey’s kind heart and the old Titanic postcard worked together to save a woman’s life.
