[The Magic School Bus] Is the bus really magical, or is it some kind of advanced technology?

Is Mrs. Frizzle a witch, or is it just some super advanced technological bus?

Definitely magic. The kids have been physically inside the engine of the bus, and it's a perfectly mundane engine; there is nothing under the hood that would let the bus do what it does. The bus (and likely the Frizzle family as well) is magical in nature, and not bound by the laws of nature or physics.
