Human Life Cycle

Overview

This 45-minute lesson introduces pupils aged 9-10 (Year 5) to the human life cycle, covering birth, growth, development, reproduction, and death. It aligns with the National Curriculum for Science in England under the category “Animals, including humans” (Programme of Study: Key Stage 2). The lesson is designed for a class of 30 students but structured with smaller group work to maximise engagement.

National Curriculum References

• Programme of Study: Science, Key Stage 2
• Relevant Attainment Target:
  • Pupils should be taught to describe the changes as humans develop to old age.
  • Recognise the stages of growth and reproduction in humans.
• Specific learning objectives from the curriculum:
  • Describe the life process of reproduction in some plants and animals (linked in simplified terms for humans)
  • Describe the changes as humans develop to old age, including gestation and growth.

Learning Objectives

By the end of the lesson pupils will be able to:

1. Identify and explain the main stages of the human life cycle: birth, growth, development, reproduction, and death.
2. Describe the physical and emotional changes that occur at different life stages.
3. Appreciate the biological importance of reproduction in continuing the human life cycle.

Lesson Structure

1. Starter Activity (5 minutes)

Activity: Quick Think-Pair-Share

• Pupils think about questions: What do you know about how humans grow? and What happens when people get older?
• Pair up for 1 minute sharing and then a 2-minute class discussion to gather prior knowledge.
• Teacher notes key points on the board under these categories: birth, growth, development, reproduction, death.

2. Teacher-led Explanation with Visuals (10 minutes)

• Use a large life cycle diagram/poster showing five stages: Birth, Growth, Development, Reproduction, Death.
• Explain each stage with age-appropriate language, emphasising physical changes (e.g. baby to toddler to child to adult).
• Introduce key vocabulary: fetus, childhood, adolescence, adulthood, reproduction, ageing.
• Show brief video clip or animation illustrating the life cycle process (2-3 minutes) — pre-selected and paused for interaction.

3. Group Activity – Life Cycle Role-Play (15 minutes)

• Organise students into groups of 5 (6 groups total).
• Each student takes a card representing a stage of the life cycle with simple facts (e.g., baby drinks milk and learns to walk; adolescent experiences puberty).
• Groups create a short skit illustrating the progression through the stages.
• They prepare a 2-minute presentation showing the stage they represent, including physical or emotional changes.
• Encourage creativity with costume props or drawings.

4. Class Sharing and Discussion (8 minutes)

• Groups present their skits in sequence.
• Teacher facilitates a whole-class reflection linking back to the stages and prompting meta-cognition:
  • Why is growth important?
  • How does reproduction contribute to life continuing?
  • What happens when humans get old?

5. Plenary Quiz and Reflection (7 minutes)

• Use a quick interactive quiz (e.g., mini whiteboards or show of hands):
  • Name the first stage of the human life cycle.
  • At what stage do humans reproduce?
  • What changes happen during adolescence?
  • Why is death a natural part of the cycle?
• Final task: Pupils write a sentence on a sticky note: "One new thing I learnt about growing up is..." and stick it on a “Life Cycle Tree” poster on the classroom wall.

Resources Needed

• Large human life cycle diagram or poster
• Life cycle stage cards for role-play
• Video or animation illustrating human life cycle stages (approved for classroom use)
• Mini whiteboards or paper for quiz answers
• Sticky notes and markers for plenary reflection
• Basic costume props (optional, e.g., hats, glasses)

---

Assessment for Learning

• Formative assessment through questioning during explanation and quiz.
• Observation of group role-play and presentations for understanding of stage concepts and vocabulary use.
• Plenary sticky note reflections to gauge individual learning and promote self-assessment.

---

Differentiation & SEND Considerations

• Provide simplified card text and additional visuals for pupils requiring support.
• Pair or group mixed ability for role-play to encourage peer assistance.
• Use visual timers to help pupils manage presentation time.
• Task scaffolded with sentence starters for plenary reflection for those who need it (e.g., "When a human grows, they...").

---

Extension Opportunities

• Research project on famous scientists who studied human development.
• Create a personal growth timeline with photos and milestones.
• Explore cultural differences in life celebrations linked to life stages (birthdays, jubilees, funerals).

This lesson plan ensures meaningful engagement with the human life cycle, promoting both scientific understanding and empathy towards natural life stages as advocated by the National Curriculum.
