I find that whenever those who make the laws which govern the schools declare that certain scientific subjects cause controversy, we will almost inevitably find that they have thereby caused a controversy surrounding those very subjects. Moreover, I find that the scientifically useful data on abiogenesis, anthropogenic global warming, and human cloning are really quite scant compared to the overwhelming evidence from disparate fields supporting the biological evolution of species over time by descent with modification.
There are interesting legal and ethical debates to be had on the matter of cloning, a fascinating series of hypotheses to be batted about regarding the formation of the most primitive complex molecules, and a wonderful debate to be had (within my peculiar field of statistical modeling and simulation) on the predictive power of climate models. These are all debates which I enjoyed greatly during and after majoring in (hard) sciences in college and (harder) maths in grad school, and I wish all high-school kids would engage in these debates vigorously and with an eye to discovering new truths.
That said, the evolution versus creation debate stands apart from those abovementioned, in that it is in no sense a scientific controversy but rather a clash of worldviews, between those who see the world solely through the eyes of faith, and those who see it with their own eyes. Ancient Hebrew/Arabic/Sanskrit cosmogonies are pitted against modern scientific theories, in the hopes that citizens will frame this particular controversy as a stark choice between religious faith and scientific knowledge. It doesn't have to be this way, but surely this is precisely how folks like Kern and Brogdon see it.
All this bluster about helping "students understand, analyze, critique, and review in an objective manner the scientific strengths and scientific weaknesses of existing scientific theories" is so much smokescreen, designed to obscure an intelligently designed wedge which starts with "scientific weaknesses" and ultimately widens out to the first verses of someone's favorite holy book. If you doubt this, just go back and look at the campaign propaganda of the legislators sponsoring and vocally supporting this bill.
