Pluto being a planet (or not) is not a scientific theory. It is a classification. Pluto orbiting the Sun is a theory.
Your kids have got to see history being made. They get to laugh at past astronomers for being so stupid as to think that Pluto was a planet in the first place.
Classifications of what is and is not a planet, dwarf planet, asteroid, dust, etc etc is not something that astronomy was just born with. At least astronomers have classifications, which is more than can be said of a lot of other things. (Bushcraft included.) Crikey, it's only a name. It's not like it's a fundamental problem with the laws of motion. Once upon a time a computer was a person, and once upon a time a hackney cabs actually had hackney horses pulling them.
