Which science project should I do?

Here;s the way I look at it. The 1st one will take more research than the others, but there will be more information about it. The 2nd one will be fun to do, but I'm not sure how much information there actually is about it out there. The 3rd one will take a lot of work, but if you do complete this one, then it will be pretty awesome! I would say do the 1st one.
