Not Quite Human is the name of a series of young adult novels by Seth McEvoy about a scientist and his android creation which resembles a teenager.
Widower scientist, Dr. Jonas Carson's lifetime work is to create an android he names Chip.
His daughter, Becky, is the only other one who knows the secret, and Dr. Carson takes a job as a science teacher at the school to keep an eye on his "son".
Chip has superior abilities such as great strength and a photographic memory, but also has a large density which gives him more weight than humans of his size.
The books were later made into a series of made-for-TV films for the Walt Disney anthology television series, starring Alan Thicke as Dr. Jonas Carson, Robyn Lively as his daughter Becky, and Jay Underwood as Chip.
