Mrs. Tesla

Mrs. Tesla was Percy's science teacher at Meriwether College Prep school.

The Sea of Monsters
For her students' final exam, she instructs them to "blow something up" by mixing chemicals together. She is pleased with Tyson and Percy's accomplishment in her class, telling them that they are the first to ace her exam in under thirty seconds, and also that they were 'natural chemists.' In reality however, Tyson accidentally spilled the chemicals into the trash, resulting in the explosion.
