（A）

The students were having their chemistry（化学）class. Miss Li was telling the children what water was like. After that, she asked her students, “What’s water?” No one spoke for a few minutes. Miss Li asked again, “Why don’t you answer my question? Didn’t I tell you what water is like?”

Just then a boy put up his hand and said , “Miss Li, you told us that water has no colour and no smell. But where to find such kind of water? The water in the river behind my house is always black and it has a bad smell。” Most of the children agreed with him.

“I’m sorry, children.”, said the teacher, “Our water is getting dirtier and dirtier. That’s a problem.”

Three kids have been learning chemistry for only a few months. But they have already begun to challenge (挑战) a world famous scientist!

   Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator (酸碱指示剂). They want it to take the place of litmus (石蕊) paper.

"We've learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other."

   British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world.

   But when the kids did some experiments in class last winter, they saw that the litmus paper didn’t turn very blue with base matter. It's hard to get a clear result.

  Will there be a better indicator than litmus paper? The three kids decided to try and find out!

    How? They went to collect over 40 plants in parks, gardens and markets. Then they ground (研磨) leaves, flowers and stems (茎) to get the pigments (色素) from them.

   The kids mixed pigments with acid and base. They spent months watching carefully to see which paper showed the best colour change. They decided it was the litmus paper!

"It's our first scientific journey, Huang said, "But it makes me want to try harder."

Many scientists find that colours can change people’s feelings. It’s very interesting. Some colours can make people feel relaxed，and some colours can make people feel nervous. Now，this kind of knowledge is being used in many places. For example, school walls are always painted green because green makes students feel relaxed. It is also good for the students’ eyes. Some books are also green or light blue for the same reason. Restaurant owners not only have to know how to make food，but also have to know how to make money. Here are some things they’ve learned from scientific studies. The colour red makes people hungry. Many fast food restaurants have red furniture or walls. Soft colours like pink and light blue make people feel relaxed，so they spend more time eating. Loud music may be nice at first，but it soon makes people want to leave. Hard seats also make customers want to eat quickly and leave. Many restaurants，especially fast food restaurants，use this knowledge to make customers eat faster.
