A period of transition
Lefrancois (2001:468) states that, “Adolescence is the transition of between childhood and adulthood, the period during which children have achieved sexual maturity but have not yet taken on the roles and responsibilities rights that accompany adult status”. Shaffer and Kipp (2007:212) also believed that the two major changes in physical development indicate the onset of adolescence. Firstly, as children enter the adolescent growth spurt, they significantly changed in shape and size and secondly, they reach puberty marking the point in their life when an individual reaches his or her sexual maturity. Puberty
According Pinyerd and Zipf (2005) cited by Shaffer and Kipp (2007:212) that the first changes appear to be seen in children is that they changed dramatically in size and shape as they go through the adolescent growth spurt.

Puberty starts with the appearance of pubic hair, breasts development in girls and, penis and testes becomes bigger in males and also sexual maturation is accompanied by a growth spurt in height and weight.

Lefrancois (2001:471) also believed that changes in height and weight are the features of pubescence which start from 12 of age. These average changes for both sexes will occur from 12 to 18.
