Nature Magazine is one of the world’s most important international weekly scientific journals. According to its website, it publishes “peer-reviewed research in all fields of science and technology on the basis of its originality, importance, interdisciplinary interest, timeliness, accessibility, elegance and surprising conclusions.”
The first issue was published in 1869. Since then, the magazine has changed quite a bit. Have a look at the graph below and discuss with your teacher how the content has evolved over the past 150 years.
You don't need to present all the findings, but, interestingly, Nature has become a lot more focused on biological and medical fields while earth sciences has decreased. Also, "other" has decreased—meaning the magazine is more focused on core topics.
