I guess my point is, there are many cases in higher level science fairs (like Siemens-Westinghouse or Intel Science Fair) where high school students seem to be presenting graduate level work.
Many interpret this to mean the kids are total geniuses, when in fact they simply tagged onto ongoing work at a university lab (given their education, probably at a level similar to a technician) and presented results from incremental work.
Not all kids have that resource or even know to pursue it (that is often the case). While these kids are certainly bright and such an accomplishment would look good on your college application, it doesn't mean they are the next Einstein. I'd be much more impressed with a solo effort or a father-son effort.
