Lesson Content/Board Summary

PLATEAUX / LOW LANDS

Meaning of Plateaux

A plateau is a large area of high, flat land that is raised significantly above the surrounding land. They are also known as tablelands because of their flat tops.

Types of Plateaux

The following are common types of plateaux:

Intermontane Plateaux: These are plateaux enclosed by mountains. Example: Tibetan Plateau.
Piedmont Plateaux: These are plateaux formed at the foot of mountains. Example: Patagonia Plateau.
Continental Plateaux: These are extensive plateaux rising abruptly from the surrounding lowlands or the sea. Example: Deccan Plateau in India, African Plateaux.
Volcanic Plateaux: These are formed by extensive volcanic eruptions. Example: Columbia Plateau in the USA.

Uses of Plateaux

Plateaux are useful in the following ways:

They are often rich in mineral deposits such as coal, iron, gold, and diamonds.
Some plateaux, especially volcanic ones, have fertile soils suitable for agriculture.
They can be ideal for livestock rearing (pastoral farming) due to being grasslands.
They are sometimes sources of rivers.
Their scenic beauty attracts tourists.

Disadvantages of Highlands (Plateaux)

Highlands, including plateaux, have the following disadvantages:

They often have rugged terrain, making transportation and communication difficult.
Building infrastructure like roads and railways is challenging and expensive.
Population density tends to be low due to harsh conditions and limited arable land.
Climate can be extreme, with cold temperatures at higher altitudes.
Limited access to water in some areas.

Meaning of Lowlands

Lowlands are large areas of land that are generally flat or gently sloping and are at a low elevation compared to surrounding areas or sea level. They are typically less than 200 metres above sea level.

Types of Lowlands

The following are common types of lowlands:

Valleys: These are low-lying areas between hills or mountains, often with a river or stream flowing through them. They can be V-shaped (river valleys) or U-shaped (glacial valleys).
Plains: These are extensive areas of flat or gently undulating land. They can be alluvial plains (formed by rivers), coastal plains (along the coast), or structural plains (formed by horizontal rock layers).
Basins: These are depressed areas of land, often surrounded by higher land. They can be drainage basins (where water collects) or structural basins (geological depressions).

Importance of Lowlands

Lowlands are important for the following reasons:

They are generally fertile, making them excellent for agriculture and food production.
Their flat terrain makes them suitable for building settlements, roads, railways, and industries.
Rivers in lowlands provide water for irrigation, domestic use, and transportation.
They are often densely populated due to ease of living and economic opportunities.
Ports and harbours are easily developed along coastal lowlands, facilitating trade.

Disadvantages of Lowlands

Lowlands have the following disadvantages:

They are often prone to flooding, especially during heavy rainfall or river overflows.
Some low-lying areas, particularly coastal plains, are susceptible to rising sea levels.
They can be vulnerable to erosion, especially along river banks and coastlines.
Poor drainage in some areas can lead to waterlogging and disease vectors.

Teaching Methods/Instructional Techniques

Discussion, Lecture, Demonstration, Question and Answer, Visual Aids

Instructional Procedures

Step 1: Introduction

Time: 5 minutes
Teaching Skill: Set Induction
Teacher’s Activity: The teacher greets the pupils and reviews the previous lesson briefly. The teacher then introduces the new topic, “Plateaux / Low Lands,” by showing pictures or models of different landforms and asking pupils to identify which ones are high and flat, and which are low and flat. The teacher states the lesson objectives.
Pupils’ Activity: Pupils respond to greetings, recall the previous lesson, observe the pictures/models, answer questions, and listen attentively to the introduction.
Learning Point: Pupils are prepared for the new lesson and understand its relevance.

Step 2: Explanation of Plateaux

Time: 10 minutes
Teaching Skill: Explanation/Demonstration
Teacher’s Activity: The teacher defines plateaux, explaining their characteristics. The teacher then discusses the different types of plateaux (intermontane, piedmont, continental, volcanic) using maps and pictures to illustrate examples. The teacher also explains the uses of plateaux.
Pupils’ Activity: Pupils listen, take notes, ask questions for clarification, and identify plateaux on maps and pictures.
Learning Point: Pupils understand the meaning, types, and uses of plateaux.

Step 3: Disadvantages of Highlands

Time: 5 minutes
Teaching Skill: Discussion
Teacher’s Activity: The teacher leads a discussion on the disadvantages associated with highlands, specifically plateaux, encouraging pupils to think about challenges related to climate, transportation, and settlement.
Pupils’ Activity: Pupils contribute to the discussion by stating potential disadvantages of living in or developing highlands.
Learning Point: Pupils identify the challenges presented by highland regions.

Step 4: Explanation of Lowlands

Time: 10 minutes
Teaching Skill: Explanation/Demonstration

Step 8: Conclusion

Time: 2 minutes
Teaching Skill: Summarization
Teacher’s Activity: The teacher summarizes the key points of the lesson, reiterating the definitions, types, uses/importance, and disadvantages of plateaux and lowlands. The teacher then assigns homework, asking pupils to draw a simple sketch of a plateau and a plain.

Learning Point: Pupils consolidate their understanding of the lesson and are given an activity to reinforce learning.

Lesson Keywords

Plateau – A large area of high, flat land.
Lowland – A large area of low-lying, flat or gently sloping land.
Valley – A low area between hills or mountains, often with a river or stream.
Plain – An extensive area of flat or gently undulating land.
Basin – A depressed area of land, often surrounded by higher land.
Highlands – Areas of elevated land, typically including mountains and plateaux.

Differentiation

For pupils who grasp concepts quickly, the teacher can ask them to research specific examples of plateaux and lowlands in Nigeria. For pupils needing more support, the teacher can provide simplified diagrams and additional one-on-one explanations, focusing on basic definitions and key characteristics.

Note for teachers using this lesson plan

Teachers should ensure to use actual maps and pictures to illustrate the different landforms. Encourage pupils to relate the concepts to their local environment where possible. A guided tour of the locality, if feasible, would greatly enhance understanding and engagement.
