Science is the best way we have of finding out about the world. Scientists collect evidence （证据）, They have ideas about the way things work. Science tests those ideas. Sometimes the test will show that the idea is not correct. If the idea passes the test, it adds to our understanding.
Scientists make observations （观察）. They may look, or listen. They may read the work of other scientists. This gives them ideas. You can do this. You can look around you. You can ask questions. You can plan a test to find out. You can discover something new.
Scientists make predictions. They say something about the future. They might say 'if I do this, then I think that will happen、Isaac Newton was a famous scientist. When he shone white light through a glass prism, he saw a spectrum （光谱）of different colors. Newton predicted what would happen if he shone the spectrum through a second prism. He thought the colors would come together and he would see white light again. He tried it. He shone a spectrum through a second prism. He was right. The colors made white light.
He discovered that white light is made up of many colors.
It's important to test your ideas. It's important to plan a fair test. A scientist wondered how a tree grows• Where does all that material come from? Was it from the soil?
He planted a young tree in a pot He weighed the pot, the dry soil and the tree at the start of his test. Years later, the tree had grown talk It had many branches and leaves. The scientist dug it up. He weighed it. The tree weighed far more than when it was young. Then he weighed the pot and the dry soil It weighed just a bit less. Where had all the new tree material come from? He decided that trees use water, and a gas from the air, to grow.

Subject: | Tips for a trip to San Francisco | ||
Hi, Li Ming, I'm glad that you are coming to San Francisco next month. But I think there is still something I should let you and your friends know before you leave. First, bring a warm jacket and sweater so that you're prepared for changes in the temperature. Even in the summer months of July and August, it gets cold. Second, many of the phone boxes at San Francisco airport and in the center of the city only accept prepaid(预先付款的) calling cards. So a prepaid phone card is needed. I suggest you buy one at the airport. Third, it's not easy to find a hotel room when you arrive. Hotels fill up quickly in San Francisco all year, especially in summer. You'd better book your room before you come. One more thing. San Francisco is a great walking city—but there are hills! Bring a comfortable pair of walking shoes if you're planning to go around on foot. Lastly, there are many wonderful cultural activities in San Francisco year round. Use the Internet to get the latest information about the activities all the time of your visit. Wish you a pleasant trip. | |||
