Vulcanicity – Modelling extrusive volcanic features

By the end of the lesson, the learner should be able to:

- Model extrusive volcanic features including shield, stratovolcano, cinder cone and lava dome using clay and materials available
- Simulate a volcanic eruption using baking soda and vinegar and record observations
- Relate the simulation of a volcanic eruption to understanding the real-life forces of pressure and gas release that drive actual volcanic events

- Use modelling clay and a film canister to build a volcano model and simulate an eruption using baking soda and vinegar
- Record observations on eruption time, height and width of the model in a table
- Download photographs of volcanic features in Kenya and make a collage to display in class

How does understanding the mechanics of a volcanic eruption help communities respond to volcanic disasters?

Vulcanicity – Review and assessment
Earthquakes – Meaning and types of earthquakes

By the end of the lesson, the learner should be able to:

- Explain how tectonic plate movements at different boundaries influence the type and intensity of volcanic activity
- Compare intrusive and extrusive volcanic features in terms of formation and impact on the landscape
- Relate the global distribution of volcanic features to human settlement, economic activities and disaster preparedness in different regions

- Answer review questions on causes, features, distribution and significance of vulcanicity
- Compare intrusive and extrusive features using a summary table
- Present and discuss answers in class for consolidation and peer review

How does the global distribution of volcanic features influence where people choose to live and how they earn a living?

Earthquakes – Causes of tectonic and volcanic earthquakes

By the end of the lesson, the learner should be able to:

- Explain how stress build-up along fault lines causes tectonic earthquakes through sudden rock movement
- Describe how volcanic activity and magma movement cause volcanic earthquakes
- Relate tectonic earthquakes along the East African Rift to the seismic risks facing cities like Nairobi and Mombasa

- Read and discuss information on tectonic earthquakes and the role of asperities and fault barriers in seismic activity
- Search for the meaning of seismic waves, fault and asperities and discuss findings in class
- Read a newspaper article on volcanic earthquakes and write summary notes

How does the movement of tectonic plates along fault lines generate the energy that causes an earthquake?

Earthquakes – Artificially induced earthquakes
Earthquakes – Distribution of earthquake zones

By the end of the lesson, the learner should be able to:

- Explain how human activities including fluid injection, underground nuclear explosions, mining and reservoir filling can cause earthquakes
- Discuss the relationship between human activities and increased seismic risk in affected areas
- Relate induced seismicity from mining operations in Kenya to the need for responsible extraction practices that protect surrounding communities

- Study photographs of mining explosions and discuss the causes of artificially induced earthquakes
- Discuss how fluid injection, nuclear explosions, mining and reservoir filling trigger seismic activity
- Write summary notes and present in class

How can human activities that change the stress balance in the Earth's crust trigger earthquakes?

Earthquakes – Effects of earthquakes on the environment

By the end of the lesson, the learner should be able to:

- Investigate the primary and secondary effects of earthquakes on the environment including ground collapse, tsunamis, landslides and fires
- Describe how earthquakes affect buildings, infrastructure and water sources
- Relate the devastating effects of earthquakes such as tsunamis and building collapses to the need for earthquake-resistant infrastructure and community preparedness in Kenya
