Again, I am finding some college specific STEM scholarships for Physics majors.  This may help you if you plan to attend one of the colleges below. See each scholarship website individually for eligibility criteria as this varies.

Limited to Chandler Gilbert Community College students, but provides up to $3,000 per semester.  This scholarship applies to Physics majors, among others. It appears financial need must be demonstrated.  The deadline for the Spring semester is Friday, January 4, 2013.
