The scientific method is used for simple experiments that students may do in the classroom or very difficult experiments that scientists are doing all over the world. It is a way of thinking that helps you to avoid drawing incorrect conclusions.
科学方法用于学生在课堂上进行的简单实验，或科学家在世界各地进行的难度非常大的实验。这是一种思维方式，可以帮助你避免得出错误的结论。
There are usually four steps in the scientific method, including observation, hypothesis, experiment, and conclusion. The steps may not always be completed in the same order, but the first step is usually observation and asking a question about your observation. For example, you had a sick stomach, and ate a candy bar. An hour later, you observed that you felt much better. Here, you can ask a question, such as, “What makes a sick stomach feel better?”
科学方法通常有四个步骤，包括观察、假设、实验和结论。这些步骤可能并不总是按照相同的顺序完成，但第一步通常是观察，并就你的观察提出问题。例如，你胃不舒服，吃了一块糖。一个小时后，你发现自己感觉好多了。在这里，你可以问一个问题，比如“什么让生病的胃感觉更好？”
The second step is to state a possible answer to the question, or a hypothesis, such as “A candy bar makes a sick stomach feel better” A good hypothesis includes three things: The explanation for the observations, it is able to be tested, and it will usually predict new outcomes or conclusions.
第二步是陈述问题的可能答案或假设，例如“一块糖果让生病的胃感觉更好”。一个好的假设包括三件事：对观察结果的解释，它能够被检验，它通常会预测新的结果或结论。
The third step is the experiment, to test the hypothesis. An experiment is a test which will either challenge or support the hypothesis. The hypothesis will then be true or false.
第三步是实验，检验假设。实验是一种挑战或支持假设的测试。然后，假设将是正确的或错误的。
The final step is to think about what happened when you tested the hypothesis and draw a conclusion. The conclusion will either clearly support the hypothesis or it will not. If the results support the hypothesis, a conclusion can be written and you can share it with the rest of the world. If it does not support the hypothesis, you may choose to change the hypothesis or write a new one based on what was learned during the experiment.
最后一步是思考当你测试假设并得出结论时发生了什么。结论要么明确支持假设，要么不支持。如果结果支持这一假设，可以写一个结论，你可以与世界其他地方分享。如果它不支持假设，你可以选择改变假设，或者根据实验中学到的知识写一个新的假设。
