The Science Teacher is an unnamed teacher at Beverly Beverly High. He appears to be fond of insects.
His voice actor is unknown due to vague crediting.
The Science teacher seems to be an average-grade science teacher. He is very knowledgeable on all matters science-related and is very passionate about science. Perhaps he is not very passionate as a teacher, but one could not ask for a better person to talk about physics, chemistry, or biology.
Like Ms. Rumsfeld, he also appears to enjoy giving bonus questions.
