2. Microorganisms: Friend and Foe

In this chapter, students explore the world of microorganisms, learning about their helpful and harmful roles. Microorganisms assist in processes such as fermentation and nitrogen fixation, but they can also cause diseases. The chapter highlights the importance of hygiene and vaccinations in maintaining health.

3. Coal and Petroleum

This chapter deals with non-renewable resources like coal and petroleum, explaining how they are formed, their extraction, and their role in our daily lives. It also addresses the environmental challenges posed by the use of fossil fuels and highlights the need for cleaner, sustainable energy sources.

4. Combustion and Flame

Students explore the process of combustion, understanding how fuel burns in the presence of oxygen. They’ll learn about different types of combustion (complete and incomplete), the structure of flames, and how combustion is applied in various day-to-day activities.

5. Conservation of Plants and Animals

This chapter emphasizes the importance of protecting our biodiversity. Students learn about endangered species, conservation methods such as wildlife sanctuaries, and the role humans play in preserving plants and animals to maintain ecological balance.

6. Reproduction in Animals

Here, students will explore the reproductive processes in animals, including sexual and asexual reproduction. They will learn how animals reproduce, the role of fertilization, and the development of embryos into young ones.

7. Reaching the Age of Adolescence

Adolescence is a period of physical and emotional changes. In this chapter, students will understand the physiological changes during puberty, including hormonal fluctuations and growth patterns. It also highlights the importance of maintaining a healthy lifestyle during this stage.

8. Force and Pressure

This chapter introduces the concept of force—what it is, how it works, and the different types of forces. Students will explore how force affects the motion of objects and how pressure is calculated, with applications in daily life, like hydraulic systems.

9. Friction

Friction is the force that resists motion. Students will learn about the different types of friction, such as static, sliding, and rolling. The chapter will cover how friction affects everyday activities and its role in machines, along with ways to reduce or increase friction when needed.

10. Sound

In this chapter, students will learn how sound is produced and how it travels through various media like air, water, and solids. They'll study sound waves, pitch, frequency, and the properties of sound, as well as its uses in communication and entertainment.

11. Chemical Effects of Electric Current

This chapter introduces students to the chemical effects caused by electric current. Students will learn about electrolysis, electroplating, and electrorefining, understanding how electric current can be used to produce chemical changes in substances.

12. Some Natural Phenomena

This chapter covers exciting natural phenomena such as lightning, earthquakes, and volcanic eruptions. Students will learn about the science behind these events, the causes, and how they affect the environment, with a focus on how static electricity plays a role in lightning.

13. Light

The chapter focuses on the properties of light, such as reflection, refraction, and dispersion. Students will explore how light behaves, the formation of rainbows, and how lenses work in optical instruments like magnifying glasses and microscopes.
