2   Materials and their structure



                   2    What are the temperatures shown on the thermometers?

                        A                            B                            C












































                    Think like a scientist

                    Measuring the temperature when you heat water

                    In this task you will take accurate measurements.


                      You will need:
                      •    beaker, Bunsen burner, clamp stand, gauze, measuring cylinder, thermometer,
                           tripod, stop watch


                    Safety
                    Wear safety spectacles. Take care when handling hot water. Always stand up to carry
                    out practical work. If you spill any hot water it will not be on you.


                    Work in groups of two or three. Before you start the activity, discuss in your group what
                    other safety measures you will take. Check these with your teacher.
