Chapter List
1. Cellular Organization of Plants and Animals
Introduces the cell as the basic unit of life in both plants and animals. Students learn about cell structure, organelles and their functions, differences between plant and animal cells, and how cells are organized into tissues and organ systems in living organisms.
2. Sense Organs
Covers the five sense organs — eyes, ears, nose, tongue, and skin — and how they help humans perceive the world. Students learn about the structure and function of each sense organ, common disorders affecting them, and how to care for and protect sense organs.
3. Photosynthesis and Respiration in Plants
Explains how plants make food through photosynthesis using sunlight, water, and carbon dioxide. Also covers plant respiration — how plants release energy from food — and the differences between photosynthesis and respiration, including their importance for life on Earth.
4. Environment and Interactions
Explores the relationship between living organisms and their environment. Topics include food chains and food webs, ecosystems, adaptation of organisms, interdependence in nature, environmental pollution, and how human activities affect the natural environment and biodiversity.
5. Atoms, Molecules, Mixtures and Compounds
Introduces the building blocks of matter — atoms and molecules. Students learn the difference between elements, compounds, and mixtures, how atoms combine to form molecules, and basic properties of common substances. Lays the foundation for understanding chemistry concepts in higher classes.
6. Air
Covers the composition of air, properties of gases in the atmosphere, and the importance of air for living things. Topics include oxygen, nitrogen, carbon dioxide, and their roles in natural processes, as well as air pollution sources and their effects on health and the environment.
7. Solutions and Suspensions
Explains the difference between solutions, suspensions, and colloids. Students learn about solutes and solvents, concentration of solutions, saturated and unsaturated solutions, and how to separate mixtures using methods like filtration, evaporation, and distillation.
8. Energy and Its Forms
Covers different forms of energy including kinetic, potential, thermal, light, sound, and electrical energy. Students learn about energy transformation, the law of conservation of energy, renewable and non-renewable energy sources, and practical applications of energy in daily life.
9. Forces and Machines
Introduces the concept of force and how forces affect motion and shape. Topics include types of forces (gravitational, frictional, magnetic), simple machines (lever, pulley, inclined plane, wheel and axle), and how machines make work easier by changing the direction or magnitude of force.
10. Properties of Light
Explores the behavior of light including reflection, refraction, and dispersion. Students learn how mirrors and lenses work, how rainbows are formed, and how light travels through different media. Practical activities help students investigate the properties of light using everyday objects.
11. Investigating Sound
Covers how sound is produced, transmitted, and heard. Students learn about vibration, pitch, loudness, the speed of sound in different media, echo, and noise pollution. Includes practical investigations to help students explore the properties of sound through simple experiments.
12. Space and Satellites
Introduces the solar system, planets, moons, and the concept of artificial satellites. Students learn about the motion of Earth and other planets, how satellites orbit Earth, uses of satellites in communication and weather forecasting, and basic facts about space exploration and the universe.
