Describe the physical differences in girls and boys before and after puberty.
What will be an ideal response?
Girls and boys are similar in weight and height and show similar rates of growth in childhood. Yet, at all ages, even before birth, boys tend to be more physically active than girls, and this difference increases during childhood. Boys engage in more physical, active play, including rough-and-tumble interactions that involve playful aggression and overall body contact. Puberty triggers many sex differences in physical attributes and abilities. After puberty, males tend to be bigger, stronger, and faster than female. Males continue to show more physical activity than females in adolescence and adulthood.
