Chapter 6: Control and Coordination

This chapter explores how living organisms regulate and coordinate their bodily functions. It provides a detailed explanation of the human nervous system, focusing on how neurones transmit messages. Additionally, it discusses the role of hormones in plants and animals, explaining their significance in control and coordination.

Chapter 7: How Do Organisms Reproduce?

This chapter is essential as it covers the fundamental concept of reproduction. It explains both asexual and sexual reproduction, with classifications based on plants and animals. Understanding this topic is crucial as it forms the basis for more advanced biological studies in higher classes.

Chapter 8: Heredity and Evolution

This chapter builds on the previous topic of reproduction, exploring heredity and evolution. It explains how traits are inherited and how genetic variations occur based on Mendelian principles. Understanding these concepts is particularly important for students interested in pursuing science or medical studies in higher classes.

Chapter 9: Light—Reflection and Refraction

The first chapter in the Physics section introduces the principles of light reflection and refraction. Students learn about the laws of reflection and their applications, including the working of a pinhole camera. The chapter also covers how light bends when passing through different substances like water and prisms.

Chapter 10: The Human Eye and the Colourful World

This chapter provides a detailed study of the human eye and its structure, including parts like the pupil, retina, and lens. It also explains common vision defects, such as nearsightedness and farsightedness, and how they can be corrected using lenses.

Chapter 11: Electricity

Electricity is a crucial topic with practical applications, making it highly relevant for board exams. This chapter introduces essential formulas used to solve numerical problems and explains how electric current flows through a conductor. It also covers key electrical terms and concepts necessary for a strong understanding of electricity.

Chapter 12: Magnetic Effects of Electric Current

This chapter explores the magnetic effects of electric current, which have numerous real-life applications. It introduces the concept of magnets and their functioning, explaining how a compass needle acts as a small magnet. Students also learn about the north and south poles of a magnet and their role in generating magnetic effects.

Chapter 13: Our Environment

The final chapter of the syllabus focuses on the Earth's ecosystem and its role in sustaining life. It explains the formation of food chains and their importance in maintaining ecological balance. Additionally, students learn about the negative impact of human activities on the environment, including pollution and global warming, making this chapter essential for understanding environmental conservation.

Tips for Preparing the Science Syllabus 2026 CBSE Class 10

The Process of Learning

• Learn scientific concepts through applications and examples.
• Pay close attention to understanding each subject's underlying theory.
• Instead of memorizing formulae, understand their meaning, purpose, and origin.
• Instead of depending just on facts you have committed to memory, solve challenges using your comprehension.

Study Regularly

• Make it a habit to study every day, even if it's only for a short while.
• Regular, brief study sessions work better than last-minute cramming the night before the test.
• To achieve greater recollection, divide the course into digestible chunks and cover each one progressively. 

Effective Time Management

• Completing the CBSE Class 10 Science Exam requires a strong grasp of time management.
• Set aside time in your study sessions to focus on each subject.
• To improve your speed and efficiency on tests, practice responding to questions in the allotted time.
• Maintain a well-organised study routine to prevent last-minute cramming.

Also, Class 10 Science and Class 10 SST can be studied together as both subjects are somehow related to each other. Students can check the chapters in the Class 10 science syllabus & also check the topic-wise division in SST Syllabus Class 10.

Remember that the trick to doing well on the CBSE Class 10 Science Exam is to have a regular study schedule and a deep comprehension of the subjects. In conclusion, the goal of the CBSE Class 10 Science syllabus is to provide students with a solid understanding of science's foundational concepts.

The syllabus, which covers a variety of topics in biology, chemistry, and physics, tries to be both difficult and understandable. Using committed study and understanding of the CBSE Class 10 Science syllabus, students may improve their scientific performance and achieve academic achievement.
