I'd just put it all in one (or two if you need it to fit), e.g.
Scholarship X: A partial tuition scholarship awarded based on academic merit.
Scholarship Y: A one-year full tuition scholarship awarded to the best tennis player on the varsity team.
etc.
The idea is to let them know you're recognized as a star, that people are willing to give you money for it, etc. I wouldn't let it be half of your activities, as they want to see what else you've been doing.
