Chapters: 5
1. A. Geographic Inquiry and Skill Development
A1 Geographic Inquiry · A2 Developing Transferable Skills
- The Scientific Method – The scientific method is the careful way scientists find out how the world works. Observe something, ask a testable question, make a hypothesis (a clear, testable guess), test it with a fair experiment (change one variable, measure one, keep the rest the same), repeat and record data, analyse it, draw a conclusion and share it so others can check. Results that fail the test are useful too: they send you back to a new hypothesis.
- Career Planning: From Knowing Yourself to Your First Job – Career planning has five steps. 1) Know yourself: interests, skills and values. 2) Explore career families and find out the work, study needed, pay and demand. 3) Plan a pathway with SMART goals and a plan B. 4) Search for jobs with a CV, cover letter, digital portfolio and interview practice. 5) Make the move from school to work and keep learning, because careers change over a lifetime.
2. B. Spatial Organization
B1 Protecting Species and Spaces · B2 Human Impacts · B3 The Earth's Ecosystems
- Natural Resource Management: Using Nature Without Using It Up – Natural resources are things from nature that people use: water, soil, forests, fish, minerals and energy. Some are renewable stocks, some are non-renewable, and some are flows such as sunlight. They are spread unevenly, so some places have surplus and others shortage. Developing a resource brings jobs and income but also costs to land, water, air and people. Good management keeps use within sustainable yield, using tools like protected areas, quotas, recycling, pricing and community stewardship.
- Biodiversity and the Effect of Human Activity on Ecosystems – Biodiversity is the variety of all the different species of organisms on Earth or in one ecosystem. High biodiversity makes an ecosystem stable, because species depend on each other for food, shelter and a steady physical environment, and it gives people food, medicines and clean air and water. A growing human population uses more resources and makes more waste. Pollution of water, land and air, land use for building, farming, quarrying and landfill, peat removal, deforestation and global warming all reduce biodiversity. We can protect it with breeding programmes, restoring habitats, hedgerows and field margins, reducing deforestation and carbon dioxide emissions, and recycling instead of dumping waste.
- Ecosystems in Depth: Biomes, Nutrient Cycles and Disruption – Biomes are large regions with similar climate and life. On land, temperature and rainfall decide the biome; in water, salt, depth, light and flow decide the zones. Matter cycles through ecosystems: nitrogen moves between air, soil, organisms and back through fixation, nitrification, assimilation, ammonification and denitrification; phosphorus cycles slowly between rock, soil, water, organisms and sediment with no gas stage. Decomposers recycle matter with oxygen (aerobic) or without it (anaerobic). Human actions such as fertiliser runoff, habitat loss, invasive species and climate change disrupt these systems; ecosystems respond with resistance and resilience.
3. C. Sustainability and Stewardship of Natural Resources
C1 Policies and Strategies · C2 Development of Natural Resources · C3 Availability and Use of Natural Resources
- Natural Resource Management: Using Nature Without Using It Up – Natural resources are things from nature that people use: water, soil, forests, fish, minerals and energy. Some are renewable stocks, some are non-renewable, and some are flows such as sunlight. They are spread unevenly, so some places have surplus and others shortage.

4. D. Ecological Systems: Interconnections and Interdependence
D1 Reducing Pollution · D2 Impacts of Pollution · D3 Ecological Processes
- Natural Resource Management: Using Nature Without Using It Up – Natural resources are things from nature that people use: water, soil, forests, fish, minerals and energy.

Good management keeps use within sustainable yield, using tools like protected areas, quotas, recycling, pricing and community stewardship.
- Environmental Stewardship: Caring for the Planet as We Use Technology – Environmental stewardship means using the Earth's resources carefully so they last, and fixing harm where we can. Every product, from a phone to a hospital machine, has a life cycle: raw materials, making, transport, use and end of life. Each stage uses energy and makes waste. Good stewards keep products longer, choose efficient machines, follow the waste hierarchy (refuse, reduce, reuse, recycle, then dispose), send e-waste to proper recyclers and support laws and company practices that protect nature. Technology can harm the environment, but it can also help: solar panels, LEDs and smart sensors cut waste.
5. E. Community Action
E1 Developing Solutions · E2 Community Land Use and Infrastructure · E3 Ecological Footprints
- Solutions: How Things Dissolve and How Much Can Dissolve – A solution is a uniform mixture of a solute dissolved in a solvent. In water (an aqueous solution) the solute breaks into particles too small to see, so it never settles and passes through filter paper. Concentration tells how much solute is present (mass % = solute ÷ solution × 100). Solubility is the most that can dissolve in 100 g of solvent at a given temperature; beyond it the solution is saturated. Evaporation, crystallisation and distillation separate solutions.
- Land Use: How Communities Decide What Each Piece of Land Is For – Land use is what people do with land: homes, shops, factories, schools, roads, parks, farms and forest. The natural environment (rivers, slopes, soil, climate) sets the first limits. Then economic, social and cultural factors such as land price, jobs, transport and zoning rules shape the pattern, often in rings around the city centre. As towns grow they can sprawl outward or grow compactly upward. Changing land use changes ecosystems, so planning and conservation matter.
- Ethics: How to Decide What Is Right – Ethics (moral philosophy) asks what we ought to do and why. Values such as honesty, kindness, fairness and respect guide choices. Three main theories help: consequences (utilitarianism, Bentham and Mill: most good for most people), duty (Kant: act on rules you could want everyone to follow; treat people as ends, never only as means) and virtue (Aristotle: build good character; virtue is the mean between extremes). Conscience is our inner sense of right and wrong. Freedom brings responsibility. Meta-ethics asks what "good" means and whether values are universal or relative. Applied ethics deals with the environment, animals, work, friendship and peace.
