I am reluctant to recommend that a young student live away from home if it requires one or more parent relocating temporarily to support the activity. And it costs the family money.
It won’t help with college admissions and won’t help a potential future med school admission. It may or may not give her a real taste of what research is like. Research is boring, repetitive and painstakingly meticulous. Science is incremental with each success is built on many failures,
D1 had a research position in high school at the local med school. (But she was old enough to drive herself to her work site and she was able to live at home.) Her job wasn’t glamorous. She cleaned a lot of animal cages, guillotined A LOT of rats, learned to carefully shave rat bellies and give injections to rats to infect them with diseases, learned how to safely handle infectious materials (materials containing live herpes, hepatitis, Epstein-Barr and other viruses)… and discovered she really didn’t like biomedical research much.
I’m not convinced that having prior research lab experience will even help her get a research lab position in college. D1 went on to do research in completely different field in college (medium energy particle physics) where her prior research experience had zero relevance so she didn’t even mention it to the PI when he asked her to work in his lab.
D2, who didn’t do research in high school, but who is a very goal-directed individual, found a research lab position she wanted and convinced the PI to hire her. (it wasn’t all that hard.) She learned what she needed to know on the job and one year later she was training both undergrads and new grad students on how to use the lab’s specialized equipment and software packages.
