    It Is Never Too Early to Think—and Communicate—like a Scientist

Who is a scientist and what is his job? A chemist doing experiments? A geologist out studying rocks? When most people think about science, they imagine characters making discoveries or finding cures （治疗方法）for new diseases. However, these leave out an extremely important part of the scientific process: communicating—sharing the results of that work.

Imagine if someone discovered something important about a disease. Other scientists need to understand the work well enough to use these new developments to make even more discoveries in the future. The public, too, needs to understand how these discoveries might influence their lives. But none of this will be possible if the work is not shared. Being a scientist goes far beyond the moment of discovery.

Without clear communication, scientists would not be able to use the work that has already been done. So how do scientists tell others about the work that they have done? How do they make sure that everything that they share is as clear and correct as possible?

Researchers publish their work in scientific journals（期刊）.These journals can be read by other researchers around the world. It is very important for these journals, and for the scientists who read them, to make sure that the research included is as correct as possible. In order to do that, articles given to scientific journals before publication first go through a process called peer review. Other scientists who do research in areas related to the work in an article are asked to read through it. Scientists also provide feedback to the writers. They bring up new questions the writer may not have considered, recognize limitations to the results being described, and also make sure that no mistakes were made during the process.

Frontiers for Young Minds is a scientific journal written for—and reviewed by young people. All of the articles in it are based on works already published in a peer reviewed scientific journal. However, while scientists are good at making sure that articles are understandable for other scientists, there are no better experts to make sure that something can be understood by young people than the young people themselves. By working together with an experts young reviewers read the article to see if any part of the article is hard to understands make it clear why the experiment was done in the way it was done and check whether the figures （数据）clearly explain the point of the article.

Basically, these young reviewers learn to think like scientists. It is never too early to start! Ask questions, learn new things, and don't forget the importance of communicating your findings.
