Community Health senior project... advice/suggestions needed!

Hello Community Health/ Public Health Nurses! I am hoping for some suggestions... I have my Community Health project coming up in a couple of months, and I originally wanted to focus my project on nutrition in schools. I found out another student is doing the same project (and lives in the same school district as I do), so now I'm trying to think of something different. I would still like to focus my project on schools, school-aged children, and families (I have three young kiddos, so I think it would be cool to do a project that might involve or impact their school). I'm drawing a blank though... maybe something more exercise related? Any ideas???

Thanks for your time, everyone!!
