Lower School Autumn Term Stunning Start
Lower school discovered the Earth's layers this week to kick start their topic Extreme Earth. We found out that our planet has a crust, mantle, outer core and inner core. The crust is the outermost layer of the Earth. It is like the skin of an apple and is extremely thin compared to the other layers. The crust is about 10 miles deep and is made up of rock and other loose materials. The mantle is the next largest layer, and it is the largest – an estimated 1,800 miles of solid hot rock. The outer core exists under the mantle and is composed of about 1,400 miles of liquid molten lava, which consists of iron and nickel. The inner core is the center-most layer of the Earth and is a solid ball of metal.
Lower school pupils rolled and molded plasticine to make their Earths layers and are now looking forward to cutting them open to reveal the different coloured layers.
