State Unified Scheme of Work for Pre-Vocational Studies JSS 2
Pre-Vocational Studies for Junior Secondary Schools Book 2
Agricultural Science textbook for JSS 2

Instructional Materials

The teacher will teach this lesson with the aid of:

Pictures or charts showing crabs, prawns, turtles, crocodiles, hippopotamus, and whales.
Whiteboard and markers/chalk.
Flashcards with names and images of aquatic animals.

Rationale for the Lesson

This lesson helps pupils understand that water bodies are home to a wide variety of animals beyond just fish. Knowing about these diverse aquatic organisms, such as shellfish, reptiles, and mammals, is important for appreciating the rich biodiversity of aquatic environments and their roles in the ecosystem.

Prerequisite/Previous Knowledge

Pupils have basic knowledge of fish and general animal classification from their earlier primary and junior secondary science lessons.

Lesson Content/Board Summary

Other Aquatic Animals

1. Shellfish

Shellfish are aquatic invertebrates with shells. They are commonly found in marine and freshwater environments.

The following are examples of shellfish:

Crab: A ten-legged crustacean with a hard exoskeleton and a pair of claws. Crabs typically walk sideways.
Prawn: A small, shrimp-like crustacean with a long body and a hard exoskeleton, often found in both fresh and saltwater.

2. Aquatic Reptiles

Aquatic reptiles are cold-blooded animals that live in water for most or part of their lives. They have scales or scutes and breathe air with lungs.

The following are examples of aquatic reptiles:

Turtle: A reptile with a hard shell that protects its body. Many species live in water, such as sea turtles and freshwater turtles.
Crocodile: A large, carnivorous reptile with powerful jaws, a long snout, and a scaly body. Crocodiles are semi-aquatic, living in rivers, lakes, and estuaries.

3. Aquatic Mammals

Aquatic mammals are warm-blooded animals that live in water and breathe air. They give birth to live young and feed them milk, just like land mammals.

The following are examples of aquatic mammals:

Hippopotamus: A large, semi-aquatic mammal native to Africa. They spend most of their time in water to keep cool and protect their skin.
Whale: A large marine mammal that lives entirely in the ocean. Whales are known for their massive size and ability to hold their breath for long periods.

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, reviews the previous lesson on fish, and then asks pupils to name other animals they know that live in water besides fish.
Pupils’ Activity: Pupils respond to the greetings, recall the previous lesson, and name various aquatic animals.
Learning Point: Pupils connect previous knowledge with the new topic and are introduced to the lesson.

Step 2: Shellfish

Time: 10 minutes
Teaching Skill: Explanation/Demonstration
Teacher’s Activity: The teacher explains what shellfish are, displays pictures of crabs and prawns, and describes their key features and habitats.
Pupils’ Activity: Pupils observe the pictures, listen attentively, and ask questions for clarification.
Learning Point: Pupils learn about shellfish as a type of aquatic animal, with crabs and prawns as examples.

Step 3: Aquatic Reptiles

Time: 10 minutes
Teaching Skill: Explanation/Illustration
Teacher’s Activity: The teacher defines aquatic reptiles, shows images of turtles and crocodiles, and explains their characteristics and adaptations to aquatic life.
Pupils’ Activity: Pupils watch the images, take notes, and identify the distinguishing features of turtles and crocodiles.
Learning Point: Pupils understand that some reptiles live in water and can identify examples like turtles and crocodiles.

Step 4: Aquatic Mammals

Time: 10 minutes
Teaching Skill: Explanation/Discussion
Teacher’s Activity: The teacher explains that some mammals also live in water, presents pictures of hippopotamuses and whales, and discusses their unique mammalian features adapted for aquatic living.
Pupils’ Activity: Pupils observe the pictures, listen to the explanations, and participate in a brief discussion about these animals.
Learning Point: Pupils learn about aquatic mammals and can distinguish examples like hippopotamuses and whales.

Step 5: Evaluation/Review

Time: 5 minutes

Teaching Skill: Questioning/Assessment

Teacher’s Activity: The teacher evaluates the learning by asking the following questions:

Mention two examples of shellfish.
Name two aquatic reptiles discussed in class.
State two aquatic mammals.
How do aquatic reptiles differ from aquatic mammals in terms of body temperature?

Pupils’ Activity: Pupils answer orally and in writing.

Learning Point: Pupils demonstrate understanding of the lesson.

Step 6: Conclusion

Time: 5 minutes
Teaching Skill: Summarization
Teacher’s Activity: The teacher summarizes the lesson by reiterating the different categories of aquatic animals discussed (shellfish, reptiles, mammals) and their examples. The teacher then assigns homework, asking pupils to draw and label two aquatic animals from each category.
Pupils’ Activity: Pupils listen to the summary, copy the homework assignment, and prepare for the next lesson.
Learning Point: Pupils consolidate their understanding of the lesson content.

Lesson Keywords

Aquatic – Living in or on water.
Shellfish – Aquatic invertebrates with a shell.

Differentiation

For slower learners, the teacher will provide simplified explanations and more direct examples, using flashcards for visual reinforcement. They will also be paired with faster learners for support. For faster learners, the teacher will encourage them to research additional examples of aquatic animals or discuss their ecological roles in more detail.

Note for teachers using this lesson plan

Teachers should ensure that pupils grasp the differences between the various categories of aquatic animals. Emphasize the unique adaptations that allow each animal to thrive in its aquatic environment. Encourage pupils to relate the lesson to local aquatic environments if applicable.
