And it does not define what "age appropriate" is or specify what legislative body is reponsible for creating and maintaining that definition.

A chasm I see between people who have differing views of this legislation is around what "sex" means. Conservatives seem to focus very heavily on the idea that this is about teachers talking about sexual intercourse. The physical acts that adults engage in. Liberals interpret the term much more broadly to cover all of the ways that human sexuality affects society and families.
From the conservative perspective, it makes a lot of intuitive sense to prevent teachers from discussing things like foreplay, BDSM, lubrication, fellatio, etc. to small children.
From the liberal perspective, it is entirely impossible to talk about damn near anything related to human family structures and relationships if anything indirectly related to sexuality is off limits. "Why do most families have a mom and a dad?" "Where do babies come from?" "Why do they look like their parents sometimes and not other times?" "What does it mean to be adopted?" "What is the difference between a dad and a stepdad?" According to the literal interpretation of the law, none of these questions can even be hinted at inside a classroom.
So which is right? The text of the law itself is ambiguous, so you have to look at the subtext. I think we could all agree that it would be wrong to ship a live walrus to someone's house without their consent. But, as far as I know, there is no law specifically prohibiting it. Should there be? Probably not.
Legislatures have finite time, so laws are passed at a point in time because those advocating it feel that it solves a particular problem that is more important than other problems that could be solved. Understanding the intent behind those pushing the law is critical to knowing what it means. The text won't give you that. You have to look at the people and their agenda.
