pictures of life stage s

Birth is the first stage of the life cycle.  Before birth, a person begins as a single cell, the tiniest building block of life. As the human cells duplicate and specialize into specific body parts, they prepare for the birth of an infant, weighing five to ten pounds.  This takes about 40 weeks from the time that the first cell starts growing. Newborn babies have more bones in their bodies than adults do - as they grow their bones fuse together.

Birth

Infancy is the second stage of the life cycle.  From birth through the first year of life, a person is called an infant. Babies can't do much for themselves. They are only just learning to recognize their surroundings, to walk and to talk. They are dependent on parents for everything - for food, changing, bathing and movement from place to place.

Infancy and Toddler

Childhood is the third stage of the life cycle.  This lasts for about ten years, from 3 to 12 years old. For the first two years after infancy, the child is called a toddler. Toddlers learn how to walk, talk, and become more independent. They can feed and dress themselves. Toddlers grow into children, and they go to school where they learn to read and write. They gain more freedom and responsibility as they learn about themselves for the rest of their childhood.

Childhood

Adolescence is the fourth stage of the life cycle.

This lasts from about age 12 to 18 years. Teenagers are quite independent, but they still need their parents to house and feed them, and pay their bills. Adolescents learn more in school. They may learn to drive and have an after-school job.

In this stage, starting with puberty, boys change and become men, and girls become women. This can be a very confusing time for a young person, trying to cope with so many changes. Teenage boys grow in spurts, but not just upwards - growth occurs first in the hands and feet, then the legs and arms, the body, and finally the head. These different phases of growth mean that teenage boys often look long and lanky. Teenage girls often mature a few years before boys. This is the time that an adolescent prepares for adulthood, growing to his/her maximum size, and is physically able to reproduce.

Adolescence

Adulthood is the fifth stage of the life cycle.

This lasts from the end of adolescence, usually age 18 to 20, to old age. Adulthood is the time that people take on different kinds of responsibilities. All of the things that our parents once provided, adults must now provide for themselves.

The life cycle usually starts over again during this stage, when, through reproduction, adults give birth to their own children. Once a person’s children are grown up and are having children of their own, an adult can enter a more relaxing time of life, with freedom to pursue hobbies and travel. Though the body begins to break down during this stage, an adult may live to an average age of 76 or even longer. 

The human life cycle repeats the same cycle of stages, from one generation to the next.

Adulthood

KWL ChartBefore you begin to study the human life cycle, make a KWL chart.

Here are some questions to help you get started.

• What changes will you go through in your life as you grow up?• When does a person begin to walk, talk and become more independent? • What do you think it means when someone is said to have reached puberty?• At what age do you become an adult?

Or

Take a digital photo of your family members and create a collage.

Or

Using a digital video camera, take a short video of your family and narrate for the viewers.

Make a podcast for the class Wiki about your project then share it with your team.

Vocabularycycle — A series of events or stages that happen one after another that lead back to a starting point, as in a circle; for example, the cycle of the seasons or the cycle of night and day.

human life cycle — The stages of growth and development throughout a person’s life, spanning the time from birth to death.

cells — The tiny, microscopic, building blocks of life, from which all living things are made; humans begin life as one cell and grow as one cell divides into trillions.

birth — The first stage of the human life cycle, when the newborn infant comes out of its mother’s body.

infancy — The second stage of the human life cycle, lasting about one year, when a person is almost totally helpless, but through the five senses, learns a lot about their environment.

childhood — The third stage of the human life cycle, lasting about ten years to age 11 or 12.

toddler stage — The earliest part of childhood, lasting from ages 1 to 3, during which time the child learns to become more independent, more active and to begin to learn the difference between right and wrong.

adolescence — The fourth stage of the human life cycle, lasting from about age 12 to 18; a confusing time when a person undergoes many physical, emotional and intellectual changes, and is preparing for adulthood.

puberty — The earliest part of adolescence, when boys and girls are physically able to reproduce and begin to show the adult characteristics of their gender.

adulthood — The fifth stage of the human life cycle, lasting from the end of adolescence through old age, when people must assume many responsibilities, become more independent, and may start their own family.

old age — The last part of adulthood
