That said, most US high schools have some sort of guidance counselor who can help you to research and identify scholarships for which you might be eligible. I recommend you make an appointment with your guidance counselor or a trusted teacher to talk about scholarships. Some scholarships focus on people pursuing certain fields of study, who have specific interests, or who are in a certain population. Others are more contest-like and require you to do something -- e.g., write an essay or make a presentation -- and the finalist or winners get a certain scholarships. You could also consider asking about scholarships from any civic or religious organization in which you or your family may be participate.
Also, on-line research might help you find scholarships.
Lastly, if you know what colleges/universities you are considering, contact their financial aid office for further assistance.
