What learners will learn
After working on this module, learners are expected to:
- recognize that changes in different dimensions are normal during adolescence (H7GD-Id-e16)
- describe changes in different aspects of growth that happen to boys and girls during adolescence
Lessons in this module
The module has one lesson, Lesson 1: Changes that Happen to Adolescence. It opens with a word-search review of the stages of human development. It then sorts changes in boys and girls, gives a reading on the five kinds of change, and ends with activities, a diary task, and a post-test.
Physical changes during puberty
The module explains that most physical changes in adolescence come from hormonal changes as the body moves from child to adult. This phase is called puberty. It starts between the ages of 9 and 16 and usually ends between 18 and 22. General changes include:
- A rapid increase in height and weight. Boys usually go through this about two years later than girls.
- The heart and lungs grow bigger and work better, more so in boys.
- Muscles develop rapidly, faster in boys. Body fat increases, more in girls.
- The reproductive organs of both boys and girls grow and develop.
Primary sex characteristics are changes directly related to sexual reproduction. Boys experience their first ejaculation, the first release of seminal fluid. Girls experience menarche, the first menstrual period, which signals the possibility of fertility. Secondary sex characteristics are changes not directly related to reproduction. The module sorts them in this table:
| Boys | Both boys and girls | Girls |
|---|---|---|
| Deeper voice; bigger Adam’s apple; shoulders wider than hips; hair on face and body; rougher skin on upper arms and thighs | Rapid growth in height and weight; head, hands, and feet grow first, then arms and legs; muscles develop rapidly; hair on the genital region; more hormones; bones develop and harden; more active sweat and oil glands | Breasts develop; hips wider than shoulders; hair grows on the underarm |
Mental, emotional, social, and moral-spiritual changes
Mental or intellectual changes. Teens become better at abstract thinking and at empathizing with others. They can be egocentric, argue to convince, and think critically. They prefer active, cooperative learning, get bored with routine, and enjoy applying skills to real-life problems.
Emotional changes. Mood swings and erratic emotions are common, often linked to hormones. Teens may feel self-conscious, easily offended, or sensitive to criticism. They may also feel that nobody understands them as they search for their identity. They can be optimistic and hopeful too. The module notes that girls may feel insecure about their body changes. It also says boys may be prone to risky behavior because of the sudden rise in hormones.
Social changes. Social wellness is described as the ability to interact with people, respect yourself and others, build meaningful relationships, and communicate well. Adolescents enjoy friends who share their interests and are loyal to peer values. They may look up to peers and media personalities for behavior, dress, and style. They may rebel against parents but still depend strongly on their parents’ values.
Moral-spiritual changes. Adolescents ask big questions about the meaning of life and reflect on their thoughts and feelings. They study their strengths and weaknesses. They rely on home and religious institutions for moral choices. They also learn to tell negotiable rules from non-negotiable ones.
How to use this module
The module follows these parts in order:
- What I Know: a pretest with 10 multiple-choice items and 5 identification items
- What’s In: a word search with eight words on human development
- What’s New: “Is this me?”, a Venn diagram sorting changes in boys, girls, and both
- What is It: the reading on the five kinds of change
- What’s More: Activity 1 “Point Out!” (fill in the word), Activity 1.2 “Time to choose” (true or false), and Activity 1.3 “Check it now!” (two-sentence answers on each kind of change)
- What I Have Learned: “Fill me up,” a summary paragraph
- What I Can Do: “Dear Diary,” where learners write about the changes they have noticed in themselves
- Assessment: a post-test in the same format as the pretest
For learners: Write your answers on a separate sheet of paper or in your activity notebook, not on the module. Answer keys are included, so use them honestly, after you answer.
For parents: Some topics, like puberty and menstruation, may lead to questions. The module encourages learners to consult their teacher or facilitator when they have difficulty.
For teachers: The pretest shows whether a learner can move ahead on their own or needs your help. The post-test checks learning at the end. The diary task shows how each learner understands their own changes.

What is It
Have you noticed that there are changes happening to you? Can you give some examples of these changes? Are these changes necessary as you grow? Read the following to understand more.
Reading is Learning
Adolescence comes with a fair share of changes. These transformations can be physical, mental, emotional, social, and moral-spiritual.
A. Physical Changes
The physical transformations observed during adolescence are, in most cases, the result of hormonal changes as the teenager’s body is transformed from child to adult. This phase, called puberty, starts between the ages of 9 and 16 and usually ends between the ages of 18 and 22.
These are some of the general changes that happen to adolescent boys and girls during puberty.
- There is a rapid increase in height and weight. Boys experience this usually two years later than girls.
- Changes happen in the circulatory and respiratory system. The heart and lungs grow bigger and work better, although the increase is more in boys than in girls.
- In body composition, muscles develop rapidly, although boy’s muscle grow faster than girls. Body fat increases, although the increase in girl’s body fat is more than boys.
- The reproductive organ of both boys and girls grows and develops.
Primary sex characteristics are changes directly related to sexual reproduction. The reproductive organs of both boys and girls grow and develop. The boys experience their first release of seminal fluid or ejaculation from the penis. The girls experience menarche or the onset of menstruation which signals the possibility of fertility among women.
Secondary sex characteristics are changes not directly related to sexual reproduction.
Table 1. Changes that Happen to Adolescence
| Boys | Common Changes | Girls |
|---|---|---|
| The voice becomes deeper. Adam’s apple becomes bigger. The shoulder becomes wider than the hips. The hair grows on the face and body. The skin on the upper arms and thighs becomes rough. | There is rapid increase in height and weight. The head, hands and feet grow faster first, then the arms and legs. Muscles develop rapidly. Hair grows on the genital region. There is a rapid increase in hormone production. The bones develop and becomes harder. Sweat and oil glands become more active | Breasts develop. The hips become wider than the shoulders. The hair grows on the under arm. |
B. Mental or Intellectual Changes
Studies have shown that the brain makes significant changes as a child grows through puberty into adulthood. As a child becomes teen, he or she is more able to think abstractly, and more importantly, more able to empathize with others. Here are some of the changes an adolescent might experience:
- Adolescents are egocentric. This means caring too much about yourself and not about other people. They argue to convince, exhibit independent and critical thought.
- Adolescents prefer active and cooperative learning activities over passive learning experiences.
- Adolescents enjoy learning skills to apply to real life problems and situations.

- Adolescents have the abilities to control and coordinate their thoughts with their actions and deeds.
- Adolescent students focus attention on what they want to listen to. They can also focus their attention on two or more things at the same time.
C. Emotional Changes
This is one of the important dimensions of health. This includes both positive and negative reactions as follows:
- Erratic emotions and behaviors, mood swings are mostly experienced and felt.

- Adolescents are easily offended and sensitive to criticism, vulnerable to one-sided arguments and criticism
- Adolescents are being optimistic and hopeful, searching for adult identity and acceptance.
- Adolescents exaggerate simple occurrences and believe that personal issues are unique to themselves.
- Adolescents believe that nobody understands them, striving for a sense of individual uniqueness and search for their identity.
- Adolescents are more emotional and makes them open to being hurt or in danger.
- Boys are also sexually active: thus, they are prone to participate at risky behavior due to the sudden increase in the manufacture of hormones.
- Girls become self-conscious because of the changes that are happening to them, giving them a feeling of insecurity and discomfort.
- Early maturing boys are usually taller and stronger; they have good body image, so they are more confident, secure and independent.
D. Social Changes
Social wellness refers to your ability to interact with people, respect yourself and others, develop meaningful relationships and develop quality communication skills.
The adolescent may act out unusual or drastic. At times, he/she may be aggressive, daring, boisterous and argumentative.
