Hello everybody ! I'm a 15 years old student in ninth grade.My country will do the selective Physics Science Fair for ISEF.The winners will have opportunity to compare on I-Sweep next year.All best students of my country will participate in this competition.Most of them will be helped very much by their Physic teachers but my physic teacher is ... ughh :@ "ohh i don't have time to spend with this things -.-"so... i talked with one of my friends older than me who will compete in ISEF to but we will helped by his professor and this is the only way.I searched on internet and i thought to make a project about Green Plant Electricity(its not that i like it but this was the only one that seemed easy enough to do ) , but when i saw the winners of last year ISEF I thought again about my choice . A Novel Paper Sensor for the Detection of Cancers < The name of the last year best project, and it is made by a fifteen years old boy , it seems difficult for a 15 year old student :P. I really want to win this competition(who doesent). Please give me an idea or anything else that might help ! _____________________________________________________________________ Thank you for your attention !
