You have a lot of scientific adventures as a science writer. When you write, you never get to just do science writing. The stuff that isn't science writing isn't any fun, like going to meetings and things. There are science writers and scientific writers. Science writers write for the public, they write in magazines, and books for children.
Scientific writers write for other scientists, in research reports, or scientific journals.
They also write technical manuals. Some science writers work for universities, like me, and they write about the things that go on in the university. Or some work for newspapers. Some are freelance writers, and they get assignments from editors. If the editor likes the idea, he assigns the freelancer an article about that topic.
