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.
