The role of microorganisms in decomposition, nitrogen fixation, and food spoilage is also discussed, along with methods to prevent the spread of infectious diseases.
Students will learn about the formation of fossil fuels like coal, petroleum, and natural gas over millions of years. This chapter covers the uses of these fuels, their products, and their environmental impact. It emphasizes the need for energy conservation and exploring alternative energy sources for sustainable development.
This chapter introduces the chemical process of combustion, where substances react with oxygen to release heat and light. Students learn about ignition temperature, rapid combustion, spontaneous combustion, and the structure of a candle flame. The chapter also explores fuel efficiency, the calorific value of fuels, and fire safety.
The chapter discusses the importance of conserving biodiversity, including plants and animals. Topics include deforestation, biodiversity, biosphere reserves, national parks, sanctuaries, and the Red Data Book. Students learn about endangered species, the role of afforestation, and reforestation in environmental conservation.
This chapter explains the process of sexual and asexual reproduction in animals. Students will learn about fertilization, embryo development, and the differences between viviparous and oviparous animals. The chapter also covers internal and external fertilization, and the role of parental care in animal reproduction.
This chapter focuses on the physical and emotional changes that occur during adolescence. Students learn about puberty, hormonal changes, and the development of secondary sexual characteristics. The chapter emphasizes the importance of personal hygiene, a balanced diet, and emotional well-being during this transitional period.
Students are introduced to the concepts of force and pressure in this chapter.
