Use a free online Volcano Lab simulation to investigate how magma properties, gas escape and pressure influence volcanic behaviour.
Volcano Lab turns volcanic eruption science into a structured classroom investigation. Students use the Dig Earth Studio Volcano Lab interactive model to change key magma and conduit conditions, make predictions, collect observations and explain why different volcanic systems behave differently.
Students investigate how:
silica affects magma viscosity
temperature affects viscosity
crystals increase effective viscosity
dissolved volatiles contribute to the volcanic gas supply
restricted gas escape can increase pressure
combinations of these factors influence eruption behaviour
The activity encourages students to think in terms of cause and effect rather than simply memorising volcano types.
This resource includes:
Student Activity Pack
Answer Key
Teacher Guide
access to the free browser-based Volcano Lab interactive experiment
Activities include predictions, controlled tests, observations, data interpretation, explanation questions and a final knowledge check.
Suitable for Earth science, volcanoes, plate tectonics and physical geography topics in secondary science and geography.

Geology Bundle | 3 Interactive Resources
Three engaging geology resources exploring volcanic processes, everyday geology and sediment transport through interactive investigations and observation. Bring geology into the classroom with three Dig Earth Studio resources designed to help students investigate geological processes and interpret evidence rather than simply memorise facts. This bundle includes: Volcano Lab Students experiment with volcanic conditions and investigate how changes in geological variables influence volcanic behaviour. Geology Around You Students discover that geology is not confined to dramatic landscapes. They investigate rocks, minerals and geological materials found in everyday surroundings and connect familiar objects and places to Earth processes. Sediment Sorter Students investigate how flowing water transports and deposits sediment. They change flow conditions and sediment supply, record results and use sedimentary evidence to interpret changing environments. Together, the resources move students between observation, experimentation and interpretation, providing a varied introduction to geological thinking. Topics include: Volcanoes • sediment transport • deposition • rocks and minerals • sedimentary environments • Earth materials • geological processes Suitable for secondary Earth Science, Geology and Geography lessons. The Dig Earth Studio interactives are free to access online. This bundle provides the structured classroom resources designed to accompany them.
Natural Hazards Bundle | 3 Interactive Labs
Three interactive Earth science investigations exploring earthquakes, volcanoes and flood resilience, with structured classroom activity packs. Bring natural hazards to life with three Dig Earth Studio investigations that allow students to explore the processes behind earthquakes, volcanic activity and flooding through interactive digital experiments and real-world-style scientific reasoning. This bundle includes: Earthquake Now Students investigate live earthquake data, identify global seismic patterns, compare earthquake depth and explore the relationship between earthquakes and plate-boundary systems. Volcano Lab Students experiment with volcanic processes and investigate how changing conditions influence volcanic behaviour. Flood Resilience Lab Students investigate runoff, flood response and different flood-management measures, exploring how changes to a landscape can influence flood risk. Each resource is designed as a structured investigation rather than simply an online simulation. Students make predictions, run experiments or analyse data, record evidence and use their observations to explain Earth processes. The accompanying classroom materials include student activities, teacher guidance and answer materials where provided. Topics include: Natural hazards • earthquakes • volcanoes • flooding • plate tectonics • hydrology • Earth science • geography Suitable for secondary Geography, Earth Science and STEM lessons. The Dig Earth Studio interactive experiments are free to access online. This bundle provides the structured classroom resources designed to accompany them.
