Scientists study the world and learn about things using a process called the scientific method(方法). By asking important questions and   16  the answers, it is possible to make amazing discoveries! Sometimes a scientist is   17  to answer his own questions, but if he has taken good notes another scientist may come along later who is able to use new knowledge to answer it.

When you use the scientific method to   18  an experiment, you start by making observations(观察) about something that  19  you. Based on your observations, you make a hypothesis. This is using  20  you know to make a smart guess about what you think could happen. Then you are ready to begin your experiment. All   21  your experiment you take down notes, which are   22   experiment date(资料). You are constantly making observations during this time. You may make discoveries that cause you to improve your experiment as you go.   23  , you conclude your experiment and begin to look over your notes to decide what it all means. Based on what you have learned, you make a final statement about   24  your hypothesis was correct or not. You have to have reasons and evidence to support what you are saying.

Using the scientific method can be difficult, but rewarding. Because all the steps are organized in a process, the   25  are more valid(可信的). When you provide observations as evidence to support what you are saying, your ideas are more likely to be accepted.

My mother was telling me about how she and her family got their first television when she was a teenager. Of course it was black and white. She said she only watch it at night. She doesn’t remember over watching it in the morning or afternoon. When I was young we had only about 3 or 4 different channels(频道). My bothers, my sisters and I would sometimes fight(打架) about which channel to watch. But we usually enjoyed the same shows. Now we can get hundreds of channels on TV. I can’t believe it! There are channels with old films, cooking, fishing and so on. It’s surprising! There is a channel for everything. I wonder how much my bothers, my sisters and I would fight if we had hundreds of channels when I was a child. Of course we had only one television set.
