Document Summary
Physical development: the brain, body, motor skills, and sexual development. From age 2 until puberty, children gain about 5-8cm in height and about 3kg in weight each year: during middle childhood (6-11) children may seem to grow very little; 5cm and 3kg in one year. Physical growth and development are again obvious at puberty, when adolescents enter a two-to-three year growth spurt (gain about 4. 5-7kg, 5-10cm: after puberty, small increases in height will continue until their mid to late teens. Skull and hands mature first, whereas the leg bones continue to develop into their late teens. Individual variations meaning that two kids of the same age can look very different depending on their maturation: cultural variations people in asia/south america/africa tend to be smaller than north. Americans/europeans/australians: cultural differences in the rate of physical growth, heredity in combination with environmental factos can influence the diseases they may encounter, and affect the rates at which they grow and heights they attain.
