Week 1
Lesson 1
Fish Classification 
In this lesson, students will learn about the classification of marine fish species. They will explore the hierarchical system of classification, including kingdom, phylum, class, order, family, genus, and species. Through examples and interactive activities, students will gain an understanding of how scientists classify different fish species based on their characteristics and evolutionary relationships.
 Week 2
Lesson 2
Overview of Major Classes of Fish
This lesson provides an overview of the major classes of fish, including jawless fish, cartilaginous fish, and bony fish. Students will learn about the key characteristics and examples of each class, such as lampreys and hagfish for jawless fish, sharks and rays for cartilaginous fish, and bony fish. 
 Week 3
Lesson 3
External Anatomy of Fish
In this lesson, students will explore the external anatomy of fish, including fins, scales, gills, mouth, and eyes. Through diagrams and interactive learning activities, students will learn about the functions of external features and how they contribute to the survival and behavior of fish in their marine environments.
 Week 4
Lesson 4
Internal Anatomy of Fish
This lesson focuses on the internal anatomy of fish, including the digestive system, circulatory system, respiratory system, and reproductive system. Students will learn about the unique adaptations of fish organs to their aquatic lifestyle and how these adaptations contribute to their survival. Through interactive media, students will gain a deeper understanding of fish internal anatomy
 Week 5
Lesson 5
Unique Adaptations and Comparative Anatomy
In this lesson, students will explore the diverse adaptations of marine fish, including physiological, behavioral, and morphological adaptations. They will learn how different fish species have evolved to thrive in various marine habitats, such as deep sea, coral reefs, and polar regions. Students will analyze similarities and differences in the anatomy of fish species and understand how these adaptations reflect their ecological roles.
 Week 6
Lesson 6
Fish Behavior
This lesson focuses on the behavior of marine fish, including feeding, mating, communication, and social interactions. Students will learn about the diverse range of behaviors exhibited by fish species and how these behaviors are influenced by environmental factors such as food availability, predation risk, and habitat. Students will develop an understanding of the adaptive significance of fish behavior.
 Week 7
Lesson 7
Fish Reproduction
In this lesson, students will explore the reproductive strategies of marine fish, including spawning, parental care, and migration. They will learn about the different stages of the fish life cycle, from fertilization and embryonic development to larval and juvenile stages. Students will gain insights into the diversity of fish reproductive strategies and the challenges they face in maintaining viable populations.
 Week 8
Lesson 8
Fish Population and Marine Ecology
In this lesson, students will explore the role of fish populations in marine ecology and the interconnectedness of marine ecosystems. Students will learn about the relationships between fish populations and other organisms, such as plankton, coral reefs, and commercial fisheries.
