Question HELP! ♣ Have a science fair idea, but need to "expand"

Hi. I have 2 science fair ideas and I need to pick by tomorrow which one to do.

1. Do preservatives really work?
*This project is great, but the version I found is really for younger grades. Any ideas on how to make it my level?

2. (this one dosen't have a title yet, but the idea is Do calcium supplements make bones stronger / stop bone loss?
*This one is great also, but bone experiments are common.

Which one would be better? Thanks for everyone's help on this one!
