      Lesson details

      Learning outcome

      I can use observable characteristics to classify animals in different ways.

      Key learning points

      1. Although animals can be very different from each other many have similar features that allow us to put them into groups.
      2. Animals can be grouped by their observable characteristics.
      3. Observable characteristics can include information about colour, size, shape and structure.
      4. The process of grouping animals based on their similarities and differences is called classification.
      5. Animals can be classified into mammals, reptiles, amphibians, fish and birds by observing body covering and structure.

      Keywords

      • Observe - To observe is to look very closely and use other senses too.

      • Groups - Groups contain similar objects according to their features.

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

      • Classify - To classify is to sort objects into groups based on their similarities and differences

      Common misconception

      Pupils may have a limited view of what an animal is: mammal with fur and four legs. This can affect the way they classify animals. Also, that its habitat is an observable characteristic.

      Use a wide range of animals including invertebrates and vertebrates, and those that live on land and in the sea, to help them look at observable characteristics when grouping.

      Teacher tip

      Wherever possible use realistic images or models of animals for the pupils to classify. Remind pupils that observable characteristics include information about colour, size, shape or structure of an animal.

      Equipment

      Pupils may prefer to use hoops for classifying animals as mammals, reptiles, amphibians, reptiles and birds.
