Liam Squires, like many students, usually answers the question “How was school today?” with an evasive answer along the lines of “I don’t know.”This is why weeks passed before his mother, Megan Squires, learned that he had spotted an error in a science textbook that the publisher, dozens of students and his own teacher had missed.
Liam, 10, had noticed that two rocks were misplaced in a diagram of the rock cycle.
The significance of his discovery was not clear to his mother until months later in March, when Liam was praised by the school district superintendent and received a letter from the textbook’s publisher.
Liam saw the mistake toward the end of a school day at H.M. Pearson Elementary School in Catlett, Va., about 50 miles southwest of Washington, D.C.
