10 lessons in this unit
Population distribution
Define population distribution, population density, sparsely and densely populated, settlement pattern and census, calculate population density from area and population using whole numbers, explain physical and human factors that influence where people live (water, fertile soil, climate, relief, jobs, transport, services, safety), and use examples from Sierra Leone and the world, deepening earlier map work.
Lesson 2Population change
Define birth rate, death rate, natural increase, migration, population growth, life expectancy and population pyramid, explain how populations change through births, deaths and migration, read a simple population pyramid and line graph of growth, describe that world population passed 1 billion around 1804 and 8 billion in 2022, and discuss factors such as health care, education and food that influence change in neutral, evidence-based terms.
Lesson 3Rural-to-urban migration
Define migration, rural, urban, urbanisation, push factor and pull factor, explain why people move from villages to towns and cities (jobs, education, services, family links, farming difficulties), describe benefits and challenges for cities (growth, informal settlements, traffic, services) and for rural areas (remittances, labour shortages), use Freetown as a general example of rapid growth, and plan simple responses.
Lesson 4International migration
Define emigrant, immigrant, international migrant, diaspora, host country and country of origin, explain that around 280 million people live outside the country where they were born (about 3.6% of the world’s people), describe common patterns (within regions, to cities, for work and study), describe how diasporas link countries, discuss contributions and challenges neutrally, and avoid assumptions about any group.
Lesson 5Reasons people move
Use the push-pull framework to analyse many reasons people move (economic, educational, social and family, environmental, safety), distinguish choices that are voluntary from moves made under pressure at a general level, explain that decisions usually combine several factors, evaluate how information and networks influence moves, and write a balanced analysis of a made-up case without judging anyone’s choices.
Lesson 6Voluntary and forced migration
Distinguish voluntary migration (chosen) from forced migration (people compelled to leave by danger, conflict, disaster or coercion), define refugee, asylum seeker, internally displaced person and humanitarian protection in age-appropriate terms, explain that the 1951 Refugee Convention and the UN refugee agency (UNHCR, founded 1950) protect refugees, refer to the transatlantic slave trade as an example of forced movement in historical, document-based and non-graphic terms, explain that people have rights wherever they are, and show empathy and respect without graphic detail.
Lesson 7Cultural exchange
Define cultural exchange, cultural diffusion, loanword, fusion, cultural heritage and cultural appropriation (introduced gently as respect), deepen earlier work on trade routes and migration by exploring how food, language, music, clothing, crafts and ideas spread, give examples from West Africa and the world (Krio language, jollof rice debate avoided, kente and country cloth, Silk Roads), and discuss how to exchange respectfully while keeping heritage.
Lesson 8Urbanisation
Deepen earlier work on rural-to-urban migration by examining urbanisation globally: define megacity, urban sprawl, informal settlement, infrastructure and sustainable city, explain that more than half of the world lives in cities and that about two thirds are projected by 2050, describe the pace of urbanisation in Africa, discuss benefits (jobs, services, innovation) and challenges (housing, transport, waste, flooding, pollution), connect to the Sustainable Development Goal on sustainable cities and communities (SDG 11), and design a simple city improvement plan.
Lesson 9Challenges and opportunities of migration
Analyse the challenges and opportunities of migration for migrants, origin communities and host communities using a balanced framework (economic, social, cultural, environmental), use evidence from approved sources and made-up data, explain remittances and brain circulation neutrally, discuss integration, language, recognition of skills and belonging, and weigh policies that support fair, safe and orderly migration without partisan positions.
Lesson 10Migration case study
Carry out a guided case study of how migration shaped one place, using Freetown and Sierra Leone as the focus (founding as a settlement for formerly enslaved people in the late 1700s, the arrival of settlers and people freed from slave ships, the development of Krio culture and language, and continuing movement into the city), use timelines, maps and documents from approved sources, separate fact from interpretation, identify different perspectives, and write a balanced case study summary with evidence.
