<p>That might be a hard major to find, since most writing instruction and writing intensive courses come from a humanities viewpoint where subjects like literature, history, art, etc. are the main subjects that one writes about. Scientists and engineers do write in school and in real life (e.g. project reports, proposals, etc.), but much of their school and real life writing is intended to be read by other scientists and engineers, rather than the general public.</p>
<p>A few ideas:</p>
<ul>
<li><p>Consider majoring in your favorite science, but taking lots of writing intensive courses in various subjects.</p></li>
<li><p>Look for schools with coursework in subjects like “history of science and technology”, “science, technology, and society”, “ethics in science and engineering”, “social implications of science and engineering”, and the like.</p></li>
</ul>
