Topic: Features of Organisms
Lesson 1: Kingdoms of Living Organisms
| Section | Details |
|---|---|
| Objective | – Understand the main features used to classify organisms into the five kingdoms (Animalia, Plantae, Fungi, Prokaryotae, Protoctista). |
| Activities | Starter (5 mins): Ask students to name some living organisms and discuss how they are different (e.g., animals, plants, fungi).Main (25 mins): 1. Introduce the five kingdoms and describe their main features: – Animalia: Multicellular, no cell walls, heterotrophic. – Plantae: Multicellular, cell walls, autotrophic. – Fungi: Cell walls (chitin), saprophytic. – Prokaryotae: Unicellular, no nucleus. – Protoctista: Mostly unicellular, nucleus present.2. Use diagrams and examples of organisms from each kingdom.Plenary (10 mins): Students match organisms to their correct kingdom and justify their classification. |
| Resources | Diagrams of organisms from each kingdom, classification charts, whiteboard. |
| Time | 40 minutes |
| Homework | Write a short description of each kingdom with one example. |
| Assessment | Students classify organisms into kingdoms and explain their reasoning during discussions. |

Lesson 2: Animal Kingdom Classification
| Section | Details |
|---|---|
| Objective | – Identify and classify organisms into the main groups of vertebrates (mammals, birds, reptiles, amphibians, fish) and arthropods (myriapods, insects, arachnids, crustaceans). |
| Activities | Starter (5 mins): Show images of animals and ask students to group them based on similarities (e.g., fur, feathers, exoskeleton).Main (25 mins): 1. Describe the main features of vertebrates: – Mammals: Fur, live birth, warm-blooded. – Birds: Feathers, lay eggs, warm-blooded. – Reptiles: Scales, lay eggs, cold-blooded. – Amphibians: Moist skin, lay eggs in water, cold-blooded. – Fish: Scales, gills, cold-blooded.2. Explain the main features of arthropods: – Myriapods: Many legs, segmented body. – Insects: 3 body parts, 6 legs, wings. – Arachnids: 2 body parts, 8 legs. – Crustaceans: Hard exoskeleton, 10 or more legs.Plenary (10 mins): Students classify animals into vertebrate or arthropod groups and justify their classification. |
| Resources | Images of animals, classification charts, worksheets for grouping animals. |
| Time | 40 minutes |
| Homework | Create a table listing the main features of vertebrates and arthropods with examples. |
| Assessment | Students classify organisms during the activity and explain their choices. |
| Past Paper Practice | IGCSE Biology 0610/22/M/J/20 Q2(b). |
Lesson 3: Plant Kingdom Classification
| Section | Details |
|---|---|
| Objective | – Understand the main features of ferns and flowering plants (monocotyledons and dicotyledons). |
| Activities | Starter (5 mins): Show images of different plants and ask students to describe their features (e.g., leaf shape, flowers, seeds).Main (25 mins): 1. Explain the main features of ferns: – Reproduce using spores. – Large fronds. – No flowers or seeds.2. Describe flowering plants and differentiate monocotyledons from dicotyledons: – Monocotyledons: Parallel veins, narrow leaves, one seed leaf. – Dicotyledons: Branched veins, broad leaves, two seed leaves.3. Provide examples of ferns, monocots, and dicots.Plenary (10 mins): Students classify given plants as ferns, monocots, or dicots. |
| Resources | Plant specimens or images, classification charts, worksheets for plant grouping. |
| Time | 40 minutes |
| Homework | Draw and label a diagram of a monocotyledon and a dicotyledon leaf, highlighting key differences. |
| Assessment | Students classify plants and explain the differences between ferns, monocots, and dicots during discussions. |
| Past Paper Practice | IGCSE Biology 0610/31/M/J/20 Q3(a). |
Lesson 4: Viruses and Their Features
| Section | Details |
|---|---|
| Objective | – State the main features of viruses, including their protein coat and genetic material.– Understand why viruses are not classified as living organisms. |
| Activities | Starter (5 mins): Ask students if viruses are living or non-living and discuss their opinions.Main (25 mins): 1. Describe the structure of viruses: – Protein coat. – Genetic material (DNA or RNA).2. Discuss why viruses are not considered living organisms (e.g., cannot reproduce independently, lack cellular structure).3. Provide examples of viruses (e.g., influenza, HIV).Plenary (10 mins): Students summarize the features of viruses and explain why they are not classified as living organisms. |
| Resources | Diagrams of viruses, video animation showing virus structure and replication. |
| Time | 40 minutes |
| Homework | Write a paragraph explaining why viruses are considered non-living and provide one example of a virus. |
| Assessment | Students describe the structure and classification of viruses during discussions. |
| Past Paper Practice | IGCSE Biology 0610/42/O/N/20 Q2(c). |
Key Notes for Teachers:
- Use visual aids like diagrams, images, and classification charts for better understanding.
- Encourage active participation through group activities like classification tasks and dichotomous key construction.
Key Notes for Students:
- Focus on the distinguishing features of kingdoms, vertebrate and arthropod groups, and plant classifications.
- Understand why viruses are not considered living organisms despite having genetic material.
