21. Life Cycle of Human Being

22. Human life cycle

23. The Human Life Cycle Stages
Birth
The start of the
human life cycle
begins after the baby
is delivered out by
his/her mother to
the world.

24. The Human Life Cycle Stages
Infancy
It is characterized as
lasting from birth through
the first year of life. The
infant is completely
dependent upon his/ her
parents or caretakers for
survival.

25. The Human Life Cycle Stages
Childhood
This takes place
between ages 1 to 10. The first
2 years, the child is called a
toddler. During this time, the
child learn how to walk. talk,
and be more self- sufficient.
The child is susceptible during
this time to learn habits and
behaviors.

26. The Human Life Cycle Stages
Adolescence
This takes place
between ages 12 and 18 and is
a critical turning point because
it is when puberty takes place.
Boys’ voices change and the
girls get their periods. As such,
they began to separate more
from parents and become
more independent.

27. The Human Life Cycle Stages
Adulthood
Last from age 18
throughout old age.
Adulthood is when human
beings are fully grown and
must provide entirely for
themselves. This is also a
significant time that adults
can give birth.

28. Science Concepts
Birth
1. There are five ( 5 ) stages in the life cycle of human
2. They are from birth, infancy, childhood, adolescence
and adulthood.
3. During infancy, the child is completely dependent
upon his/ her parents or caretakers for survival.
4. During childhood, the child learns how to walk, talk,
and be more self-sufficient.
5. Adolescence is a critical turning point because it is
when puberty takes place.

29. Life Cycle of Humans
Birth
Adulthood Infancy
Childhood
Adolescence

30. Direction: Answer with Birth, Infancy, Childhood, Adolescence or
Adulthood.
1. The child learns how to walk, talk and be more self-sufficient.
2. Stage when puberty takes place.
3. Starts of the human life cycle.
4. The infant is completely dependent upon his/ her parents or
caretakers for survival.
5. This is also a significant time that adults can give birth.
6. The child is susceptible during this time to learn habits and
behaviors.
7. Human beings are fully grown and must provide entirely for
themselves.
8. Boys’ voices change and girls get their periods.
