Human Growth Curve

• Why a girl will grow bigger than a boy at age 12 years old? Kenapa budak perempuan lebih besar daripada budak lelaki pada umur 12 tahun?– Puberty (akil baligh)

• Physical change during puberty ? Perubahan fizikal semasa akil baligh– Grow of armpit & pubic hair (tumbuh bulu ketiak dan bulu

pada kemaluan)– Grow Taller (semakin tinggi)– Menstrual cycle starts (bermula kitar haid)– Enlargement of breast (Buah dada membesar)– Enlargement of hips (Pinggul membesar)
