My son is a rising senior in high school. He just recently began doing chemistry research with a professor at a local university. They have made great progress and my son will be giving a talk at a department meeting this week (as well as writing a paper on the work). The professor has raised the issue of my son entering into one of the competitive Science competitions (Siemens, Intel STS, Intel ISEF, etc.). We are total newbies to this (my son has never entered a science fair of any kind, etc). I would appreciate any advice that anyone may have regarding the time commitment to enter such a competition, if it is even worthwhile to do so if he has never entered a more low-end/regional competition before, potential pitfalls, etc.
Also, will the results of any of these competitions impact potential college acceptances, or will the results come out too late to impact anything (impacting college application process is a plus but not driving the decision on whether or not to participate).
Finally, the professor has also indicated that he believes the work is of such significance as to be worth submission to a reputable journal. I would assume that such a paper would be co-authored with the professor. If he/they do submit a paper for publication in a journal , does that preclude participation in a Science competition, or can he scope out a portion of the research that was strictly his and separate from the combined work that is published.
