Start chapter

Describing Motion Around Us

Explore how motion is described in everyday life using position, distance, displacement, speed, velocity, and acceleration. Learn to interpret motion through position–time and velocity–time graphs, and apply kinematic equations for constant acceleration. Includes an introduction to motion in a plane and uniform circular motion.

Start chapter

Exploring Mixtures and their Separation

This chapter explains how mixtures are classified as homogeneous or heterogeneous, and as solutions, suspensions, or colloids. Learn how concentration and solubility help describe solutions, and how separation methods like crystallization, distillation, chromatography, separating funnel, centrifugation, and coagulation are used in daily life and labs.

Start chapter

How Forces Affect Motion

Class 9 Science Chapter 6, “How Forces Affect Motion”, explains how forces change an object’s state of rest or motion. It covers force as a vector, balanced vs unbalanced forces, friction, and Newton’s three laws with real-life examples and simple experiments.

Start chapter

Work, Energy, and Simple Machines

Class 9 Science Chapter 7 explains how work is defined for a constant force, how energy changes when work is done, and why power depends on time. It also introduces simple machines—pulleys, inclined planes, and levers—and shows how they make tasks easier without reducing total work.

Start chapter

Journey Inside the Atom

Explore how the idea of the atom evolved from ancient thinkers to Dalton, Thomson, Rutherford and Bohr. Learn about subatomic particles, atomic number, mass number, electronic configuration, valency, isotopes and isobars. Includes key experiments like cathode rays and the gold foil scattering experiment.

Start chapter

Atomic Foundations of Matter

Explore how matter is built from atoms and why reactions follow fixed laws. This chapter covers the Law of Conservation of Mass, the Law of Constant Proportions, and Dalton’s Atomic Theory, then connects them to bonding, formula writing, and basic mass calculations.

Start chapter

Sound Waves: Characteristics and Applications

Explore how sound is produced by vibrations and how it travels through solids, liquids, and gases. Learn sound wave basics—compressions, rarefactions, wavelength, frequency, amplitude, intensity, and speed—plus reflection effects like echo and reverberation. Includes real-life applications such as ultrasonography, sonar, and echolocation.

Start chapter

Reproduction: How Life Continues

Explore how living beings continue life through reproduction in Class 9 Science (Exploration). This chapter explains asexual methods like vegetative propagation, budding and spore formation, and sexual reproduction through meiosis, pollination and fertilisation, with clear links to human reproduction, pregnancy and health.

Start chapter

Patterns in Life: Diversity and Classification

This chapter explains biodiversity and why it is vital for ecosystem balance and human life. Students learn how scientists classify organisms using visible features, cell structure, nutrition and ecological roles. It also covers India’s biodiversity hotspots, evolution of diversity, and modern scientific naming.

Start chapter

Earth as a System: Energy, Matter, and Life

Explore how Earth works as one connected system where energy from the Sun and cycling of matter link the geosphere, hydrosphere, cryosphere, atmosphere, and biosphere. Learn why uneven heating drives winds and ocean currents, how biogeochemical cycles sustain life, and how human activities disturb these balances.
