Science project idea's?

You need something you can test easily. That's going to rule out most tests involving medicine I would guess. You need to start with an observation or something you're curious about and would like an answer to. Start by keeping notes of potential ideas - just things you see or questions that cross your mind. Once you've got a list of things, see which ones you could test with an easy to arrange experiment. Here's a tip - your first ideas are likely to be impractical or too difficult. That's why I recommend the note taking. Brainstorm it before you start and it will save trouble later.
