That's because there isn't a controversy about evolution within science.
If it is controversial to you, tell your children that elswhere than in science classes.
"That's because there isn't a controversy about evolution within science."
Yes, there is.
Of course it is...and here's the reason: at the end of the day, you must adhere to a belief in the existence of the theory of evolution's missing pieces the same way people of faith adhere to their beliefs in God--by believing they will be discovered/revealed.
The intellectually honest evolutionist admits to this, the intellectually dishonest does not. Hence, controversy.
And that's because the gatekeepers of the science establishment consider any close critique of Darwin to be prima facie unscientific.
Incredibly, Darwin is to the 21st century what Aristotle was to the 11th.
Let us review: Science relies on forming a hypothesis, testing the hypothesis through experiment, and evaluating the results of the experiment to determine whether they support the hypothesis. Science thrives on such things as sharing of data, reproducible results, and peer review.
The entire world would welcome a well-designed, controlled experiment that would either prove or disprove speciation through natural selection. Without that, however, all that Darwin and his disciples have provided us with is a hypothesis...and acceptance of it then becomes philosophy, not science.
Of course everyone is welcome to his or her philosophy, but let's call it what it is, all right?
