The CBSE Class 10 Science syllabus covers a range of topics across three main sections: Physics, Chemistry, and Biology. Here’s a detailed overview of the latest syllabus:
1. Chemical Substances – Nature and Behaviour
- Chemical Reactions: Types of reactions, balancing of reactions, and concept of oxidation-reduction.
- Acids, Bases, and Salts: Properties of acids and bases, indicators, and preparation and properties of salts.
- Metals and Non-Metals: Physical and chemical properties, reactivity series, and corrosion.
- Carbon and its Compounds: Bonding in carbon, nomenclature, and properties of carbon compounds like alkanes, alkenes, alkynes, and alcohols.
- Periodic Classification of Elements: Modern periodic table, periodic trends, and group-wise properties.
2. Physics
- Light: Reflection of light, mirrors, and lenses, formation of images.
- Human Eye and Colourful World: Structure of the eye, defects, and their correction, dispersion of light, and the rainbow.
- Electricity: Ohm’s law, series and parallel circuits, and the concept of resistance.
- Magnetic Effects of Electric Current: Electromagnetism, magnetic fields, and applications of electromagnetism.
- Sources of Energy: Renewable and non-renewable sources, conservation of energy, and environmental impact.
3. Biology
- Life Processes: Nutrition, respiration, transport in plants and animals, and excretion.
- Control and Coordination: Nervous system, hormonal coordination in humans and plants.
- Reproduction: Reproductive health, sexual reproduction in animals and plants, and human reproductive system.
- Heredity and Evolution: Mendelian genetics, variation, and evolution theories.
- Our Environment: Ecosystem, environmental issues, and sustainable development.
- Management of Natural Resources: Conservation of resources, sustainable practices, and environmental impact.
Practical Work
- Experiments related to Chemistry, Physics, and Biology: Preparation of solutions, measuring physical properties, and biological experiments.
The syllabus aims to provide a comprehensive understanding of fundamental concepts in science and encourages scientific inquiry and experimentation. For detailed content and specific chapters, refer to the official CBSE curriculum or prescribed textbooks.
