The various superhero RPGs are the way to go. Aberrant is my favorite, though there are good D20 options as well. Aberrant powers are science based (energy and quantum mechanics). Also, super hero stuff has been popular recently, so the students will probably like it. Depending on how out there your school is, they may have a problem with science being so powerful, though if that is the case, I'd get the hell out of there.
Thanks, /u/Kozlem!
Aberrant is available as a scanned PDF on DriveThruRPG, and it frequently shows up on Amazon at decent prices.
We're in early development on the second edition.
Let me know if you have any more questions about it.
