My memory of school at that age was they'd teach you one thing as though it was the absolute truth, then the following year tell you it was all a lie (or over-simplification) and actually it works like this.

Then the next year they'd do it again.

We'd occasionally catch them at it when in Chemistry they'd tell us electrons worked one way and in Physics they'd say they worked another.

Anyway, I can definitely see how an enquiring mind might want to move past all this and find out The Truth.
