Of course, in real scientific studies there are no doctrines that one must follow in order to do experiments or research.
Do I have to believe a literal interpretation of Genesis, including creation about 6,000 years ago, to participate?
One reason we are holding this Science Fair is to show that creationists are capable of conducting good science. We also want to provide an opportunity to encourage creationist students with an interest in science to pursue their goals. In light of these intentions, the invitation to participate is open to any 7–12 grader who agrees with the Answers in Genesis Statement of Faith.
The cost of participating is $5/student, but I don't see anything on how much it would cost to attend the fair. In the past other creationist 'science' fairs have been good evidence for how otherwise bright children are being misled.
