Question
Discuss height and weight changes that take place during middle and late childhood.
During the elementary school years, children grow an average of 2 to 3 inches a year until, at the age of 11, the average girl is 4 feet, 10 inches tall, and the average boy is 4 feet, 9 inches tall. During the middle and late childhood years, children gain about 5 to 7 pounds a year. The weight increase is due mainly to increases in the size of the skeletal and muscular systems, as well as the size of some body organs. Proportional changes are among the most pronounced physical changes in middle and late childhood. Head circumference and waist circumference decrease in relation to body height. A less noticeable physical change is that bones continue to ossify during middle and late childhood but yield to pressure and pull more than mature bones.
