Science
Class 10.

This chapter introduces the concept of chemical reactions, where substances interact to form new substances with different properties. Students learn how to write and balance chemical equations and understand various types of reactions such as combination, decomposition, displacement, and redox reactions. The chapter also explains corrosion and rancidity, helping learners relate chemistry to everyday life.

This chapter focuses on the properties and uses of acids, bases, and salts in daily life. Students explore indicators, pH scale, and the importance of pH in nature and human body. Common chemicals like baking soda, washing soda, and plaster of Paris are discussed to show how chemistry is applied practically.

In this chapter, students study the physical and chemical properties of metals and non-metals. It explains extraction of metals from ores, corrosion, and prevention methods. The chapter also highlights the uses of metals and non-metals in daily life and introduces the concept of alloys.

This chapter explores carbon’s unique bonding nature and its ability to form a vast number of compounds. Students learn about hydrocarbons, functional groups, ethanol, ethanoic acid, soaps, and detergents. The chapter emphasizes the importance of carbon compounds in fuels, food, medicines, and everyday materials.

Life Processes explains the basic functions necessary to maintain life, such as nutrition, respiration, transportation, and excretion. Students understand how plants and animals carry out these processes and how different organs work together to keep organisms alive and healthy.

This chapter describes how living organisms respond to stimuli through control and coordination systems. It covers the nervous system, hormones, and endocrine glands in humans, as well as plant hormones. The chapter helps students understand how actions and reactions are regulated in living beings.

This chapter deals with the various methods of reproduction in plants and animals. Students learn about asexual and sexual reproduction, reproductive health, and human reproductive systems. The chapter highlights the importance of reproduction in the continuity of life.

Heredity and Evolution explains how traits are passed from parents to offspring and how variations occur. Students study Mendel’s experiments, inheritance patterns, acquired and inherited traits, and the concept of evolution. This chapter connects genetics with the diversity of life on Earth.

This chapter introduces the behavior of light when it reflects from mirrors and refracts through lenses. Students learn ray diagrams, mirror and lens formulas, and magnification. The concepts help explain everyday optical phenomena and form the foundation of optics.

This chapter explains the structure and functioning of the human eye and common eye defects. It also discusses dispersion of light, scattering, and atmospheric phenomena like blue sky and sunrise colors. The chapter links physics concepts to natural observations.

Electricity introduces electric current, potential difference, resistance, and Ohm’s Law. Students learn how electricity flows in circuits and how electrical energy is calculated. This chapter builds a strong foundation for understanding household and industrial electrical systems.

This chapter explains the relationship between electricity and magnetism. Students study magnetic fields, electromagnets, electric motors, and generators. The chapter shows how electrical energy is converted into mechanical energy and vice versa.

Our Environment focuses on ecosystems, food chains, energy flow, and environmental balance. Students learn about biodegradable and non-biodegradable substances, ozone depletion, and conservation of resources. The chapter emphasizes the importance of protecting the environment for sustainable development.
