In this module

you are expected to describe the changes that occur

during puberty.

Get photos of your mother and father or older brother and sister when they are

young. Study their photos and answer the following questions.

People grow and experience changes in their body over time. You were just small

when you were born. You grew a little bigger when you were in kindergarten. Now that you

are already in fifth grade, you have grown taller and bigger. You have changed a lot.

Puberty is a stage characterized by rapid developmental changes.

​Changes start to

happen to young boys whose age ranges from 12 t 14 years old.

Girls, on the other hand, start to experience puberty earlier. They begin to observe changes when they are 10 to 12 years old. ​

​

​These changes are caused by sex hormones from their ovaries and testes.

​

​Puberty occurs during adolescence.

​Girls start to grow into women and boys into men. Puberty is the period when the reproductive organs begin to mature.

​

​Menstruation in girls.

​

​Sperm production in boys starts during this period.

Each person has different growth rate. Your growth spurt may begin earlier than our classmates. Some many begin later than the rest of the class. Period s of growth also differs among individuals. Some may longer or shorter than others.

A person’s body hair may grow abundantly. Others may have less body hair.

​Some girls develop larger breast or broader hips. Breast of some girls may be smaller but their hips are broader.

​

​These changes are influenced by the traits each person receives from his/her parents.
