                                               LN – What is inside the Earth?

               Learning Objective - Students can name and describe the layers of the interior of
               the Earth.


               Internal Structure of the Earth

                            The structure is made up of different layers: the
                              crust, the mantle and the core.

                            Internal Structure – Materials that make up the
                              inside of the Earth.
                            External Structure – Materials that make up the

                              surface of the Earth.
                            Crust – The outer layer of the Earth. It is made up of rocks.

                            Mantle – The layer of the Earth below the crust which consists of
                              magma. It is about 3000 km deep.
                            Core – The centre of the Earth. It is about 3400 km thick. It is made of
                              metals like iron and nickel.



               Learning Outcome - Students learnt about the different layers of the interior of
               the Earth.



               Let’s do an activity:


               Children will draw the internal structure of the Earth and label it.
