Volcanoes and Earthquakes — Year 4 Lesson Plan
National Curriculum: Geography — physical geography: volcanoes and earthquakes (KS2)
Overview
Pupils investigate why volcanoes and earthquakes occur, focusing on the structure of the Earth and the movement of tectonic plates. They locate major earthquake and volcanic zones on a world map, and explore the human and physical impacts of these natural hazards on people and environments.
Learning Objectives
- Describe the structure of the Earth (crust, mantle, outer core, inner core).
- Explain why volcanoes and earthquakes occur at tectonic plate boundaries.
- Locate major volcanic and earthquake zones on a world map.
- Describe the impact of a volcanic eruption or earthquake on people and the environment.
Key Vocabulary
Suggested Lesson Structure
Show images or a short clip of a volcanic eruption or earthquake aftermath. Ask pupils: 'What do you already know about why these happen?' Collect prior knowledge on a class mind map.
Use a labelled diagram to explain the structure of the Earth. Introduce tectonic plates and how their movement causes both volcanic activity and earthquakes. Show a world map with plate boundaries and overlay with locations of major volcanoes and earthquake zones (e.g. Pacific Ring of Fire).
Pupils mark tectonic plate boundaries and locations of major volcanoes/earthquakes on a blank world map. Discuss: 'What pattern do you notice?' Compare with populated areas and consider what this means for people living there.
Pupils write a fact file on a specific volcanic eruption or earthquake (e.g. Mount Etna, 2011 Japan earthquake), covering: location, cause, short-term and long-term impacts on people and environment.
Share one or two fact files. Ask: 'Why do people choose to live near volcanoes despite the risks?' Discuss benefits (fertile soil, tourism, geothermal energy).
Common Misconceptions
- Pupils often think earthquakes only happen far away — many earthquake zones are in populated areas and some seismic activity occurs in the UK.
- Some pupils believe that volcanoes only erupt from mountain-shaped structures — submarine volcanoes and rift volcanoes also exist.
- Confusion between magma (below ground) and lava (above ground) — these are the same material in different locations.
Prior Knowledge
Pupils should already be able to:
- Familiarity with world maps and the names of continents and oceans.
- Basic understanding that the Earth is made up of layers.
- Prior work on natural hazards or physical geography.
