Document Summary

Chapter 9: physical and cognitive development in middle and late childhood. Physical growth during the elementary school years is slow, but consistent. Children grow 5 to 7. 5 cm a year until, at the age of 11, the average girl is about 1. 48m and the average boy is 1. 45m. Children gain about 2. 3 to 3. 2kg which can be attributed increases in size of the skeletal and muscular systems and the size of some body organs. Muscle mass and strength increase as baby fat decreases. Children double their strength capabilities during these years. Boys are generally stronger than girls because of their greater number of muscle cells. Head circumference and waist circumference decrease in relation to body height; these proportional changes are among the most pronounced physical changes during this time. Total brain volume stabilizes by the end of middle and late childhood, but there are significant changes in various structures and regions of the brain that continue to occur.
