10 lessons in this unit
Land use
Define land use, identify main uses (farming, housing, forests, mining, roads, markets, protected areas), explain how land use depends on the land and needs of people, show land use on a simple map, and discuss sharing land fairly.
Lesson 2Farming
Describe types of farming (crop farming, livestock, mixed, subsistence and commercial), name Sierra Leonean crops (rice, cassava, groundnuts, palm oil, cocoa, coffee), explain the farming year (seasons), identify tools and challenges, and discuss sustainable farming.
Lesson 3Fishing
Describe fishing (river, lake, sea, fish farms), name methods (nets, lines, traps, canoes, trawlers), explain its importance for food and livelihoods in coastal and river communities, identify challenges such as overfishing, and discuss safe and sustainable fishing.
Lesson 4Forestry
Describe forests and forestry (planting, caring for and harvesting trees), list forest products (timber, firewood, fruit, medicine, fibre) and services (clean air, water, shade, habitat), name Sierra Leone examples such as the Gola Rainforest and Western Area Peninsula Forest, and explain the harms of deforestation and ways to protect forests.
Lesson 5Mining introduction
Introduce mining (taking minerals from the ground), name Sierra Leone minerals (diamonds, iron ore, bauxite, rutile, gold), explain why they are valuable and how mining gives jobs and income, describe challenges (safety, environment, land restoration, fair sharing of benefits), and teach safety and respect for workers without graphic detail.
Lesson 6Water resources
Identify sources of water (rain, rivers, streams, wells, springs, taps, the sea), explain uses (drinking, cooking, washing, farming, power, transport), describe the water cycle simply, explain safe and clean water, and discuss saving and sharing water.
Lesson 7Settlement locations
Explain why settlements grow where they do (water, fertile land, harbours, trade routes, safety, resources), use Freetown, Bo, Makeni and Kenema as examples, understand site and situation, recognise risks (flooding, landslides, erosion), and discuss careful planning.
Lesson 8Environmental impacts
Explain how human activities affect the environment (clearing land, farming, mining, fishing, building, waste, pollution), distinguish positive and negative impacts, give local examples, and describe effects on air, water, soil and wildlife, with hope and action.
Lesson 9Responsible resource use
Explain renewable and non-renewable resources, describe the three Rs (reduce, reuse, recycle) and a fourth (repair), explain sustainable use, give examples (water, trees, soil, minerals, energy), and plan responsible actions at school and at home.
Lesson 10Local environmental enquiry
Carry out a guided local environmental enquiry: ask a question, plan safe observations, collect and record evidence (observation, simple counts, photographs, maps), analyse patterns, propose responsible actions, and present findings, linking land use, water and human activity.
