Grouping materials


               1  Your teacher will give you some objects made from different

                  materials. Use two sorting circles or hoops to compare and sort them.

                 You can use the photographs below as one example of sorting.

               2  Put each group inside a sorting circle.

                  Why is grouping objects by colour not scientific?






              Objects are often made from more than one
              material. Look at this bicycle and answer the

              questions using the words in the box.


                What is the                                   What is the

                  handle                                   frame made of?
                 made of?

                                                               What is the
