@kutter I read that same book when my son was a freshman in HS. (He’s now a freshman in college.) Back then, I had him look at the list of lofty goals and mark ones that he liked. We used those to start a shared Google Doc with ideas about what he could do during school years and summers. His favorites in the list were:
There were a bunch that didn’t resonate at all. Since there were already plenty that fit him, he didn’t go on to make up more.
Anyway, that was our starting guidance when looking for summer and school-year opportunities. He has done some cool astronomy things and some cool computer things. He got to work on curriculum design for elementary kids. And, he did some unrelated things that he still loved. No time travel work yet 
, but he will likely be working on a research project for NASA at JPL this summer.
Anyway, if she loves science, make sure she has the opportunity to shine in math. That keeps the doors open for any science field. Some comp-sci background is super useful these days in almost any science field, including biology.
