There was a movie that I remember watching in the early 90s, I think, that has been bugging me.
All I really remember is that the main female character, possibly with light brown hair, was a teenaged alien who ended up on Earth (possibly Southern California based on the weather) after her ship crashed, and there is a scene where she and a boy she meets run into a teacher and shatter a jar holding cow's eyes for a biology lab. She identifies one of the eyes as being from a blind cow, which the teacher was surprised by. This happens at a high school, as the boy is a student there. Weird bit to remember, but it stuck with me.
I thought it might be a Disney TV movie (my memory of watching it was as part of a Halloween season movie marathon that included The Worst Witch, which could have been Nickleodeon as well, I don't quite remember) but not according to Wikipedia's list of made for TV Disney movies from 1985-1993.
