She doesn’t need to do research in HS or attend a selective college in order to do this type of work down the road. It’s great if she enjoys it, but it needs to be because she wants to, and not because it may set her apart and help her get into a selective school (sorry to be repetitive). My daughter interviewed for a specific scholarship at Pitt (great school, but not one of the highly rejective) and she met many, many students who did research..and published…in HS. While many do not do it, it is also not uncommon.
The lab doesn’t matter. Whether it is famous or not doesn’t matter. What matters is the experience, what she takes away from it, the transferable skills she learns, relationships, etc. This type of work may help her decide if she really likes it.
A part time job is also an outstanding EC for the reasons noted above.
One of my kids did a lot of research in college. When she interviewed for grad school this research rarely came up - despite it being relevant to her degree. What DID come up all the time was her teaching (TFA), where she gained all kinds of transferable skills.
This is very similar to having a part time job in HS.
