1 of 2 The National Strategies Secondary Secondary Framework in Science, 5.2 Changing earth 5.2 Changing Earth Year Yearly learning objectives Amplification – pupils could learn to Strategies for progression Rich questions 7 recognise the processes involved in the formation of rocks recognise, using simple models, the processes of sedimentation, erosion and weathering in the formation of rocks, e.g. in sedimentary rock Create experimental opportunities to consolidate pupils’ models of the processes involved in the formation of sedimentary rocks and explore their misconceptions. (This should be done first, before moving to igneous and metamorphic.) Were rocks made yesterday? Can rocks be recycled? Plan structured whole-class discussion and independent pupil work around the formation of fossils, sedimentary, metamorphic and igneous rocks and their occurrence in the environment. Is a rock always a rock? Create experimental opportunities to model the processes involved in the formation of other rocks. Involve pupils in activities to recognise the different types of rocks and to articulate why this is useful. 8 describe the processes involved in the formation of sedimentary, metamorphic and igneous rocks and use the characteristics of the rocks to explain how they formed describe the processes involved in the formation of sedimentary rocks describe the effect of heat and pressure on the formation of igneous and metamorphic rocks as a possible progression from sedimentary rocks explain, using models, how some of the characteristics of rocks are linked to biological, physical and chemical processes of formation 9 use the rock cycle as a model to explain the cyclical nature of rockforming processes and the timescales over 00215-2009PDF-EN-01 explain how the ideas of biological, physical and chemical rock-forming processes are linked use the rock cycle as a model to Explore with pupils the processes involved in rock formation and identify the links between them. Why study rocks? Discuss as a class, and allow pupils to research independently, some of the short- and long-term cycles in nature, e.g. sunspots, ice ages, water cycle. Where is Pangaea? Create experimental opportunities to model the stages in the rock cycle and explore pupil misconceptions, e.g. using confectionery, comparing the strengths and weaknesses of each model. Do all rocks come from volcanoes? Provide opportunities to use the rock cycle to identify the relative timescales involved in the development of the Earth. Support pupils in using data and observations about earthquakes and volcanic activity as evidence for changes in the Earth’s surface over time. Involve pupils in a class discussion on the nature of the scientific data that is used as evidence for the Do rocks tell stories? Do continents move?

Have natural disasters always occurred? Is the plate tectonic theory true? Do mountains change size? Can volcanic activity be predicted? Why do they have monorails in Japan? apply and use the plate tectonic theory to critically evaluate a number of scenarios explore how movement of the plates and the active zones of the Earth can be used accurately to make predictions about future events © Crown copyright 2009
