Working like a scientist


              Identifying and classifying



              When you work as a scientist it is important to identify

              different things such as: materials, plants, animals, and

              parts of the body.
              One way that scientists learn about these things is to put

              them into groups, and this is called classifying. Here we

              can see that  materials have been sorted into two groups.

              These groups are magnetic materials and materials that

              are not magnetic.

                                                       We have sorted

                                                        materials into

                                                         two groups.
