      Introducing observable characteristics

      Lesson details

      Learning outcome

      I can group objects using observable characteristics.

      Key learning points

      1. Objects can be organised into groups based on what they have in common.
      2. Observable characteristics can include information about colour, size, shape or structure.
      3. Observable characteristics help us to sort objects into common groups.
      4. A Venn diagram and a Carroll diagram are both ways of presenting objects belonging to more than one common group.

      Keywords

      • Group - To group things is to put similar things together.

      • Common - To have something in common is to share interests or other characteristics with someone or something.

      • Observable characteristic - An observable characteristic is a feature or property of a living thing that we can see or use our other senses to observe.

      • Diagram - A diagram is a simplified representation of information.

      Common misconception

      Pupils sometimes rely upon an organism’s habitat to classify it, rather than its physical features; this can lead to misunderstandings and misclassification.

      As you model groupings, be clear to use observable features of the objects you are grouping - focus on what you can observe as a characteristic of being human.

      Teacher tip

      It is more manageable to identify observable characteristics of up to ten pupils rather than the whole class. Be aware of differences which may be due to sensitive issues.

      Equipment

      None required.
