Look at it another way, if we include Divine intervention as a cause for something then there would be no true sciences. We could dismiss interactions as God's work. Science is not a religion is does not teach truths, it's a mechanism to understand how the world works. Science class are not there to teach students what's true and what's not, they are there to teach them how to perform science. Like it or not Evolution is the basis of modern biology and must be known if you are too understand how it works. Intelligent Design adds nothing to the curriculum.
