      Changes in old age

      Lesson details

      Learning outcome

      I can describe changes in humans as they develop into old age.

      Key learning points

      1. Old age is the last period of human life.
      2. Old age in adulthood is believed to begin at about 65 years.
      3. During old age, hair can become more grey and hearing and vision can deteriorate.
      4. During old age, bones can shrink in size, and muscles generally lose strength and flexibility.
      5. We can find answers to questions about human development in old age by speaking to elderly people.

      Keywords

      • Human - People are a type of animal called humans.

      • Develop - To develop is to grow or change gradually.

      • Adult - The adult is a mature form of a plant or animal.

      • Elder - Humans past the age of 65 are considered to be elders.

      • Elderly - An elderly person is an older person past the age of 65.

      Common misconception

      Pupils may think that all elders are like their grandparents or other older people they know, whether they are fit and active or more frail and sedentary.

      Using the resources to support, explain that all humans are different and so there'll be differences in how they age. Also make it clear that old age can span up to 40 years so there'll be differences between someone who is 65 and someone who is 95.

      Teacher tip

      Inviting a familiar elderly person into the lesson, such as an older staff member or pupil's grandparent, will be a great way for children to get answers to their questions first-hand. Make sure to guide them to being sensitive when asking their questions.

      Equipment

      An elderly person or people to answer children's questions.
