Grade 12 Humanities: Geography

In this unit, 'Fundamentals of human geography', you learn to analyse population and resources. You work with exam-style questions and written reasoning. You see it, say it, then do it alone.

• Place it: find where and when 'Fundamentals of human geography' happens, on a map, a timeline or in a local example.
• Gather: read or listen to two short sources and note who is speaking and why.
• Use it: analyse population and resources. Give a reason and one piece of evidence for every point.
• Weigh it: say what another person might think, and why, before you decide.

Step by step.

1. Step 1, Read a population pyramid. A wide base means many children and high birth rates; a narrow top means few old people. A column-like shape means low birth and death rates. Compare two pyramids by age groups: 0-14, 15-64 and 65 and over. Ask what services each country will need, such as schools or pensions.
2. Step 2, Calculate the dependency ratio. Dependency ratio = (children 0-14 + people 65 and over) divided by working-age 15-64, multiplied by 100. Worked example: 25 million children and 15 million older people with 60 million working-age: (25 + 15) / 60 x 100 = 66.7. About 67 dependants for every 100 workers.
3. Step 3, Classify resources. Renewable resources, such as sunlight, wind and well-managed forests, are replaced naturally. Non-renewable resources, such as coal and oil, are used up on human timescales. Carrying capacity is the number of people an area can support with its resources. Discuss whether trade and technology can raise it.
4. Step 4, Analyse water per person. A widely used teaching guide, not a legal standard, treats below 1,700 cubic metres per person per year as water stress, below 1,000 as scarcity and below 500 as absolute scarcity. Example: 51 billion cubic metres for 40 million people gives 51,000,000,000 / 40,000,000 = 1,275, so water stress.
5. Step 5, Add projection. If the 40 million people grow at 1.5 percent a year for 10 years, population becomes 40 x 1.015 to the power 10, about 46.4 million. Water per person becomes 51 billion / 46.4 million, about 1,099 cubic metres, close to scarcity. Explain two ways the country could respond.
6. Step 6, Your turn: a country has 30 million people and 36 billion cubic metres of renewable water. Calculate water per person and classify it. Answer: 36,000,000,000 / 30,000,000 = 1,200 cubic metres per person per year, which is water stress.

Activity. About 40 to 50 minutes of class work, then one short practice task for home. Keep evidence: a timed paper and an error log.

Standard to meet. Analyse population and resources: at least 70 percent on an exam-style task, with the method shown.

In this unit, 'India people and economy', you learn to describe resources and industries. You work with exam-style questions and written reasoning. You see it, say it, then do it alone.

• Place it: find where and when 'India people and economy' happens, on a map, a timeline or in a local example.
• Gather: read or listen to two short sources and note who is speaking and why.
• Use it: describe resources and industries. Give a reason and one piece of evidence for every point.
• Weigh it: say what another person might think, and why, before you decide.

Step by step.

1. Step 1, Describe the population base first, because people supply labour and markets. The 2011 census counted about 1.21 billion people, with a literacy rate of about 74 percent and a sex ratio of about 943 females per 1000 males. These are 2011 census figures, so check the current figure. Open your answer with these figures before moving to resources.
2. Step 2, Describe mineral resources by place. Coal comes mainly from Jharkhand, Odisha and Chhattisgarh; iron ore from Odisha, Jharkhand, Chhattisgarh and Karnataka; oil from Mumbai High offshore and from Assam. Sketch an outline map and shade each belt, so location is part of every statement you make.
3. Step 3, Describe farm-based resources and the industries that use them. Rice and wheat are the main food crops, while cotton, jute and sugarcane feed factories. Cotton mills grew at Mumbai and Ahmedabad near cotton land, and jute mills lined the Hugli river near Kolkata. Name the raw material for each industry.
4. Step 4, Explain why an industry sits where it does, using five factors: raw material, power, transport, market and labour. Steel plants at Bhilai, Rourkela, Bokaro and Jamshedpur stand near iron ore and coal, because carrying heavy raw material is costly. Write one deciding factor for each plant.
5. Step 5, Describe a newer industry for contrast. Information technology needs skilled people and good connections rather than coal, so firms cluster in Bengaluru and Hyderabad near colleges and airports. Make two columns, steel and IT, and compare raw material, location pull and workers needed.
6. Step 6, Your turn: describe one resource belt and one industry linked to it, giving a place and a reason. Answer: Coal in Jharkhand and Odisha gives power for the steel plants at Bokaro and Rourkela; coal and ore are heavy and costly to carry, so plants are built close to the mines.

Activity. About 40 to 50 minutes of class work, then one short practice task for home. Keep evidence: a timed paper and an error log.

Standard to meet. Describe resources and industries: at least 70 percent on an exam-style task, with the method shown.

In this unit, 'Practical work in geography', you learn to do map and data practicals. You work with exam-style questions and written reasoning. You see it, say it, then do it alone.

• Place it: find where and when 'Practical work in geography' happens, on a map, a timeline or in a local example.
• Gather: read or listen to two short sources and note who is speaking and why.
• Use it: do map and data practicals. Give a reason and one piece of evidence for every point.
• Weigh it: say what another person might think, and why, before you decide.

Step by step.

1. Step 1, Do a scale practical. A representative fraction of 1:50,000 means 1 cm on the map is 50,000 cm, or 0.5 km, on the ground. A road measures 6.4 cm on the map, so the real length is 6.4 x 0.5 = 3.2 km. Write the RF, the working and the unit.
2. Step 2, Read contours, which join points of equal height. A path starts on the 200 m contour and ends on the 300 m contour, 2 km away on the map. Gradient is 100 m over 2000 m, which is 1 in 20. Contours close together show a steep slope; wide gaps show gentle ground.
3. Step 3, Draw a dot map. Choose a value for one dot, such as 10,000 people. A district with 235,000 people needs 235,000 / 10,000 = 23.5, so draw 24 dots. Place the dots where people actually live, not in an even grid, and add a key stating what one dot means.
4. Step 4, Draw a choropleth map. Take literacy rates from 12 to 68 percent. The range is 56, and for four classes the width is 14: 12 to 26, 26 to 40, 40 to 54 and 54 to 68. Shade light to dark, give each class a key box, and put a boundary value in the higher class.
5. Step 5, Handle a data table. Monthly rainfall in mm is 5, 8, 15, 30, 70, 180, 320, 290, 190, 60, 15, 4. The total is 1187, the mean is about 98.9 mm per month, and the wettest month is July at 320. Draw bars for rainfall, label both axes with units, and give the graph a title.
6. Step 6, Your turn: a map has an RF of 1:25,000 and two villages are 8 cm apart. Find the real distance. Answer: 1 cm is 25,000 cm, which is 0.25 km, so 8 cm is 8 x 0.25 = 2 km.

Activity. About 40 to 50 minutes of class work, then one short practice task for home. Keep evidence: a timed paper and an error log.

Standard to meet. Complete map and data practicals: at least 70 percent on an exam-style task, with the method shown.

In this unit, 'Geographical perspectives on selected issues', you learn to analyse an issue using evidence. You work with exam-style questions and written reasoning. You see it, say it, then do it alone.

• Place it: find where and when 'Geographical perspectives on selected issues' happens, on a map, a timeline or in a local example.
• Gather: read or listen to two short sources and note who is speaking and why.
• Use it: analyse an issue using evidence. Give a reason and one piece of evidence for every point.
• Weigh it: say what another person might think, and why, before you decide.

Step by step.

1. Step 1, State the issue as a focused question: should farmers in a dry district keep growing water-hungry rice while groundwater falls? Define groundwater as water stored in rock beneath the surface and reached by wells. Name the place, the time span and who is affected, because a narrow question can be analysed.
2. Step 2, Gather evidence of different kinds. Quantitative evidence includes well-depth records, rainfall and crop area. Qualitative evidence includes farmer interviews and photographs. Record the source and date of each. Our example record shows the water level at 8 m below ground in 2010 and 14 m in 2020.
3. Step 3, Analyse the numbers. The level fell 14 - 8 = 6 m in 10 years, which is 0.6 m per year, or a 75 percent increase in depth. If the trend continues, the level reaches 14 + 0.6 x 10 = 20 m by 2030. State clearly that this is a projection, not a fact.
4. Step 4, Compare viewpoints using the evidence. A farmer needs water for income, a town needs drinking water, and the environment needs wetlands to stay filled. Rice uses far more water than millets. Write one sentence per viewpoint and tie each to a specific piece of evidence, not an opinion.
5. Step 5, Weigh options against criteria: cost, effect on water, and time to work. Drip irrigation saves water but needs money for equipment; switching to millets cuts demand; rainwater harvesting refills wells slowly. Score each option and explain the trade-offs. Then state your conclusion, with its limits.
6. Step 6, Your turn: a well record shows 10 m in 2015 and 16 m in 2025. Find the yearly fall and predict 2035. Answer: the fall is 6 m in 10 years, so 0.6 m per year; by 2035 the level would be 16 + 6 = 22 m if the trend continues.

On the slide: L1 Basic · My place and my map

Notes: Name your home, street and one nearby place and point to them on a simple picture map. Notes: draw the route from the classroom to the gate with four landmarks; learners walk it and say left or right at each turn.

On the slide: L2 Awareness · Map keys and weather

Notes: Read a simple map key and describe daily weather in four words. Notes: use a map with symbols for road, river and school; learners find all three, then record sun, cloud, rain or wind for five days and count how many days were dry.

On the slide: L3 Foundation · Continents, oceans and climate

Notes: Locate the seven continents and five oceans and describe one climate zone. Notes: label a blank world outline from memory, then compare a hot wet place with a cold dry one by temperature, rainfall and plants, and say how people dress and build differently.

On the slide: L4 Practitioner · Rivers and population density

Notes: Explain how rivers shape land and calculate population density. Notes: density = people divided by area; 12,000 people on 40 square km gives 300 per square km. Learners compare an area with 18,000 people on 90 square km (200 per square km) and say which feels more crowded.

On the slide: L5 Specialist · Fieldwork and grid references

Notes: Plan a small field investigation, present results in a graph and give a six-figure grid reference. Notes: measure a stream width at five points: 2.1, 2.8, 3.4, 3.9 and 4.6 m, mean 3.36 m. Learners write a hypothesis and name one source of error.
