If you mean a pro-Creation science fair project, then you're out of luck. Unless you're prepared to be completely dishonest (or limit your research to completely dishonest people), you won't find any real science in Creationism. It's not because of bias, convention, or an "atheist agenda" as is so often claimed (I personally know lots of scientists with a strong religious faith). It's just that Creation proposes a supernatural event - the creation of the world by God. Since science is the study of the natural world, the supernatural would be outside of it's purview. What's more is that you can't subject Creation to the scientific method. It doesn't build a conclusion from gathered evidence, but rather starts with the conclusion that we were created, then works backwards from there. Finally, every argument that I've heard is a classical logical fallacy - the argument from ignorance. "We don't know how X evolved, so therefore it had to have been created." This sort of fallacy doesn't hold up if you apply it to other concepts - for example, 300 years ago, we didn't know why people got sick... so does that mean until the germ theory was thought up, disease was actually caused by God's displeasure? The biggest problem, though, is that the sole supporting evidence for Creation comes from the Bible. Every culture has their own creation story... so why is it that Biblical creation is more valid than, say, Navajo creation? The simple answer is "because the Bible says so." Where does this authority come from? Because God says the Bible is His word. How do we know that the Bible is His word? Because it says so in the Bible. It's a circular argument from authority. Don't get me wrong, though - I'm not knocking the Bible. It's a perfectly good example of religious faith. In the end, it comes down to belief and faith, though, not objective scientific evidence. To try and shoehorn belief into science degrades both - science becomes less objective, and religion loses it's aspect of faith. So, in short, I don't think you'll be able to find a good science project that mixes religion and science. The two don't have to conflict, but they really can't overlap.
