App update 2025
The NCERT science books for classes 6 to 12 are a cornerstone of science education in India. These books are renowned for their:
* Clear and Concise Explanations: Concepts are presented in a straightforward and easy-to-understand manner, making them accessible to students of varying learning styles.
* Focus on Practical Learning: The books emphasize hands-on activities and experiments, encouraging students to explore scientific concepts through observation and inquiry.
* Engaging Illustrations and Diagrams: Visual aids are used effectively to support textual information and make learning more interactive.
* Comprehensive Coverage: The books cover a wide range of scientific disciplines, including physics, chemistry, biology, and environmental science.
Here's a brief overview of the key topics covered in each class:
Class 6:
* Science: Introduces fundamental scientific concepts, including the scientific method, states of matter, living and non-living things, and the solar system.
* Our Environment: Explores the components of the environment, the food chain, and the importance of conserving natural resources.
Class 7:
* Science: Builds on Class 6, covering topics such as nutrition, fibers and fabrics, heat, and changes around us.
* Our Environment: Delves into different ecosystems, air and water pollution, and the role of forests and wildlife.
Class 8:
* Science: Introduces more complex concepts like force and pressure, friction, sound, and reproduction in animals and plants.
* Our Environment: Focuses on cell structure, microorganisms, and the importance of cleanliness and personal hygiene.
Class 9:
* Science: Divided into Physics, Chemistry, and Biology. Covers topics such as motion, gravitation, matter in our surroundings, cell structure and function, and diversity in living organisms.
Class 10:
* Science: Also divided into Physics, Chemistry, and Biology. Covers topics such as light, electricity, acids, bases, and salts, heredity and evolution, and the human eye.
