Working like a scientist



           Identifying and classifying


           Identifying is the process of naming something, for example

           an apple or an orange. We can name them because they have
           features we recognise. Classifying is organising things

           into groups. We classify objects, materials and living

           things in groups by looking at the ways in which they
           are similar or different. We can usually classify these

           things by asking a series of ‘yes or no’ questions.
           For example, does a flower have brightly coloured

           petals? Does the flower have a scent? The answers

           to these questions will help us decide if the flower is
           pollinated by insects or wind.


           Pattern seeking


           Pattern seeking involves observing, recording and analysing

           data. The patterns we observe can help us to identify a trend or
           relationships between one or more things. We often find

           patterns in nature where we cannot easily control the

           variables. For example:
           •  a pattern in the relationship between seed size and

              the time it takes a seed to germinate

           •  a pattern in the type of material that sound travels
              through best.
