What you’ll learn

  1. The First YearsIdentify the five stages of human life and describe the baby and child stages.Humans have a life cycle with five main stages: baby, child, teenager, adult, and elderly. Every person begins as a baby who needs full care, then grows into a child who gets taller and learns to talk, read, and make friends.
  2. Growing UpDescribe the teenage stage and how a person reaches adulthood.Between about 10 and 19, a child becomes a teenager, and the body grows quickly and changes into an adult body — a normal part of everyone's life. Teenagers keep learning and become more independent, and around 18 to 20 they reach adulthood, fully grown and able to care for themselves and others.
  3. Adult and BeyondDescribe the adult and elderly stages and explain how the cycle repeats.Adults are fully grown and can care for others, including having children — which begins a new life cycle. As adults grow older they reach the elderly stage, the last one, full of memories and wisdom. From baby to elder, every person travels the same cycle, generation after generation.
