      Good and ill health

      Lesson details

      Learning outcome

      I can describe what is meant by physical and mental health and can identify factors and symptoms associated with ill health.

      Key learning points

      1. People have both physical health and mental health.
      2. Physical health and mental health range from good to ill.
      3. Changes in normal body appearance, function and behaviour can be symptoms of ill health.

      Keywords

      • Physical health - Physical health is the condition of your body.

      • Mental health - Mental health is how you feel, think and act.

      • Symptom - An unusual change in a person’s normal appearance, function or behaviour might be a symptom of ill health.

      • Disease - Disease is a persistent deviation from a person’s normal appearance, function or behaviour.

      Common misconception

      Only thinking about physical and not mental health; thinking health is a binary of "healthy or ill".

      The lesson draws upon research on students' understanding of 'health' as a concept to specifically tackle the above misconceptions.

      Teacher tip

      Research suggests that asking children to draw is a useful technique for probing their understanding of topics such as health and disease, enabling them to convey concepts that may be sensitive or beyond their current vocabulary.
