Need Girl Scout Gold Award Ideas?

I am a senior girl scout and I am in the middle of doing my Girl Scout Gold Award. I have completed all the pre-requisites but I need some ideas for the main project. Im not sure what to do for a good and meaningful project. Can someone provide some more ideas, other than the ones posted on the Girl Scout website? For my service project, I volunteered at the California Science Center as an educator about many different topics in science. I was thinking of basing the project off of something health related, or even sports since I am an athlete. But any ideas, I would be glad to accept.
