Classification of Crops by Life Span and Uses Agricultural Science JSS 1 First Term Lesson Notes Week 9
Lesson Plan Presentation
Subject: Agricultural Science
Class: JSS 1
Term: First Term
Week: 9
Age: 11-12 years
Topic: Classification of Crops
Sub-topic: Based on Life Span and Uses
Duration: 40 minutes
Behavioral Objectives
By the end of the lesson, students should be able to:
- Classify crops based on their life span (annual, biennial, perennial, ephemeral).
- Identify crops based on their uses (e.g., oil crops).
- Explain the characteristics of each crop classification.
Keywords: Life span, Annual, Biennial, Perennial, Ephemeral, Oil crops
Set Induction
The teacher shows pictures of different crops and asks, “How can we group these crops? What are the different ways to classify them?”
Entry Behavior
Students have a basic understanding of different types of plants and their uses from previous lessons.
Learning Resources and Materials
- Pictures of various crops
- Charts showing crop classifications
- Drawing materials (pencils, paper)
Building Background/Connection to Prior Knowledge
Students are familiar with basic plant types and uses. This lesson expands on classifying crops based on life span and uses.

Content
Based on Life Span
- Annual Crops: Complete their life cycle in one year.
- Example: Maize – Grows from seed, produces ears, and dies within a year.
- Biennial Crops: Complete their life cycle in two years.
- Example: Carrot – Grows leaves and roots in the first year, flowers and seeds in the second year.
- Perennial Crops: Live for more than two years and often produce harvests each year.
- Example: Cocoa – Produces fruit every year and lives for many years.
- Ephemeral Crops: Live for a very short period, often less than a year, and complete their life cycle quickly.
- Example: Lamb’s Quarter – Grows rapidly and completes its life cycle in a few months.
Based on Uses
- Oil Crops: Grown for their oil-rich seeds or fruits.
- Example: Soybean – Used to produce soybean oil.
- Food Crops: Cultivated for consumption as food.
- Example: Rice – A staple food crop.
- Fiber Crops: Grown for their fibers used in textiles and other products.
- Example: Cotton – Used to make fabrics.
- Medicinal Crops: Cultivated for their medicinal properties.
- Example: Neem – Used in traditional medicine for various ailments.

Class Activity Discussion
- What are the different types of crop classifications based on life span?
They are annual, biennial, perennial, and ephemeral. - Can you give an example of an annual crop?
Maize is an example of an annual crop. - What is a biennial crop?
A biennial crop completes its life cycle in two years. Carrot is an example. - What are perennial crops?
Perennial crops live for more than two years and produce harvests each year. Cocoa is an example. - How long do ephemeral crops live?
Ephemeral crops live for a very short period, often less than a year. Lamb’s Quarter is an example. - What are oil crops?
Oil crops are grown for their oil-rich seeds or fruits. Soybean is an example. - Can you name a fiber crop?
Cotton is a fiber crop used to make fabrics. - Why are medicinal crops important?
They are cultivated for their medicinal properties. Neem is an example. - What is the main use of food crops?
Food crops are cultivated for consumption. Rice is a staple food crop. - How does cotton benefit us?
Cotton provides fibers used in making textiles and clothing.
Presentation
- Step 1: The teacher revises the previous lesson on “Plant Forms.”
- Step 2: The teacher introduces the new topic: “Today, we will learn about how crops are classified based on their life span and uses.”
- Step 3: The teacher explains each classification type, provides examples, and discusses their characteristics. Students will engage in discussions and answer questions about different crop classifications.
Teacher’s Activities
- Show examples and pictures of different crop types.
- Explain the classifications and characteristics of each crop type.
- Guide students in discussing and identifying crop classifications.
Learners’ Activities
- Identify and classify crops based on life span and uses.
- Discuss examples and characteristics of each classification type.
- Complete the fill-in-the-blank and short answer questions.
Assessment
- Classify a list of crops based on their life span and uses.
- Describe the characteristics of annual, biennial, perennial, and ephemeral crops.
- Identify the use of different crops and explain their importance.
- Answer the evaluation questions and participate in class discussions.
Evaluation Questions
- What is the life span of annual crops?
- Name an example of a biennial crop.
- How long do perennial crops live?
- What is an ephemeral crop?
- Classify soybean based on its use.
- Provide an example of a fiber crop.
- What is the primary use of medicinal crops?
- Name a crop that grows for more than two years.
- Explain the term “ephemeral crop.”
- Describe the use of rice in agriculture.
Conclusion
The teacher summarizes the classifications of crops based on life span and uses. Students are assigned to classify and describe additional crops as homework. The teacher marks the class activity and makes necessary corrections.
