Lesson Details
Key learning points
- Humans continuously grow taller from birth through to the end of puberty.
- Growth rate is maximum during infancy and adolescence.
- Girls are often taller than boys at 12 to 14 years, but men are generally taller than women as adults.
- Humans are taller now than in the past, due to improved nutrition and health.
- We can find out about changes in height by measuring humans of different ages.
Common misconception
Pupils may think that humans only grow on their birthdays or in short, intermittent spurts rather than growth being continuous throughout childhood and adolescence.
Using the lesson resources to support, explain that growth is continuous throughout youth until adulthood.
