Answer:
Dear student,
In girls - Breast size begins to increase. Skin of nipples at the tips of breasts begin to darken. Also, girls begin to menstruate at around this time.
 
In boys - Boys begin to have new thick hair growth on the face, their voices begin to crack, the penis occasionally begins to become enlarged and erect, either in daydreams or at night.
