A fundamental difference between science and creation science is that science advances knowledge, where creation science advances itself.
Creation science will never have an independent set of experiments because that's not the pursuit of creation science. Creation science is about affirmation and not discovery. Mainly affirmation for the Xians that want to believe already. The creatiom museum wasn't made to pull in non-believers and convert them. It was made to milk, err I mean attract Xians who already want to believe in what they are being presented. They just need an Animatronic dinosaur and whatever else to comfort them in what they believe to be true. Note: The most obvious experiment related to that is to visit a dinosaur bone site and test for the presence of hominid bones among the dinosaur ones. Of course creation science doesn't want you to do that because you won't find any. You only hear more of what Coyote calls the Xian "What if's?" on why human bones don't appear with dinosaur ones.
You must also keep in mind that religion itself doesn't encourage questioning of any kind. In fact some believe that questioning Jesus as the Messiah even once is instant condemnation to hell for eternity. Experimentation is one of the ultimate forms of questioning and creation science also doesn't encourage that. They don't want the average joe to discover things and advance their knowledge, they want them to believe what they say without question. Most of the time since what they teach is to fellow Xians they don't get much push back anyway. Experimentation is the scientists way of saying "Show me the money" errr I mean "Show me the data". Creation science is about convincing others (and often times themselves) about what they want (and sometimes desperately need) to believe. Not about what the observed data really shows.
Experimentation is almost entirely useless when used against almost any creationist hypothesis. The reason for this, is because almost every experiment that can be done relating to creation science can use the phrase "God must have intervened" to fix any problems that do not provide the correct results. Any experiment that runs into a problem can immediately apply the "Goddidit!" step and fix the results to whatever they want them to be. Sort of like having a giant cosmic easy button they can push anytime they need an explanation that doesn't fit the facts. Of course this completely nulls out the whole point of the experiment and creation scientists know it. Can you imagine how unenforceable certain laws would be if that were allowed as evidence? Well you as can plainly see the devil put the fingerprints on the murder weapon and placed the defendants DNA all over the crime scene. Of course that would be laughed out of court the same as it should be laughed out of anywhere near calling itself science.
