      More about human development

      Lesson details

      Learning outcome

      I can plan relevant questions to ask humans about changes as they grow.

      Key learning points

      1. Scientists ask relevant questions in order to find out more about the world.
      2. A survey is a method of gathering information using relevant questions.
      3. A survey is usually taken from a sample of people with the aim of understanding populations as a whole.
      4. Different types of questions can be used in a survey and they must be planned carefully.

      Keywords

      • Question - A question is a type of sentence which asks something.

      • Relevant - Something that is relevant is connected to what is happening or being discussed.

      • Population - The population of a place is all of the people living there.

      • Survey - A survey is a set of questions used to gather information.

      • Sample - A sample of a population means a part of that population.

      Common misconception

      Pupils may think that human development milestones happen at the same time for everyone.

      Using the lesson resources to support, explain that humans are all different and so grow and develop at different rates. This is why we need surveys to find out more information, as one rule cannot be applied to all humans.

      Teacher tip

      Pupil’s family members could be invited into school to answer children's survey questions. This would give children a range of ages to speak to, and make their results relevant to their own lives.

      Equipment

      None required.
