Lesson details

Key learning points

  1. Humans continuously grow taller from birth through to the end of puberty.
  2. Growth rate is maximum during infancy and adolescence.
  3. Girls are often taller than boys at 12 to 14 years, but men are generally taller than women as adults.
  4. Humans are taller now than in the past, due to improved nutrition and health.
  5. We can find out about changes in height by measuring humans of different ages.

Keywords

  • Puberty - Puberty is a time when human bodies go through changes to become adults that are able to reproduce.

  • Growth rate - Growth rate is the rate or speed at which something gets bigger.

  • Average - An average is a number that is calculated by adding amounts together and then dividing the total by the number of quantities.

  • Measure - To measure is to use equipment to find numbers to describe a feature of something such as its length, weight, size or time.

  • Result - The result of a test or enquiry is what happened or what was found out.

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.

If possible, source clothing for a range of different ages so children can observe how growth rate differs across different stages of development. For example, jumpers or trousers for children aged 1 month, 6 months, 1 year, 18 months and 2 years will show this difference in a really visual way.
