It has also been tried to explain why microorganism is harmful and causes various diseases to humans, animals and plants. These dangerous microorganisms cause food poisoning. In this chapter, then, different methods of food preservation are explained. The chapter culminates with the nitrogen fixation and nitrogen cycle that is explained by a diagram.
Chapter 3 Synthetic Fibers and Plastics
This chapter describes how artificial textures and plastics are managed which is intended for classification. As with synthetic fibers, synthetic fibers, plastics, choice and characteristics of plastics as a material and environment are part of the major principles of this chapter. Chapter 3 class 8 science book gives a detailed description of synthetic fiber and its different types (rayon, nylon, polyester and acrylic). Also try to explain in detail about the characteristics of synthetic fibers. After that, introduce students to the properties, properties and effects of plastics in the environment.
Chapter 4 Materials Metals and Non-Metals
In chapter 4 explains the world of metals, non-metals, properties, and employment. This part helps students to classify components into metals and non-metals based on their metal properties. Physical properties of metals and non-metals, chemical properties of metals and non-metals, use of metals and non-metals are a part of the important topics mentioned in the chapter.
Chapter 5 Coal and Petroleum
This chapter is about natural resources and taxonomy. It teaches that coal, petroleum and natural gas are fossil fuels that have been formed millions of years ago from the dead remains of living organisms.

Then, biosphere reserves, flora and fauna, endemic species, wildlife sanctuaries, national gardens, red data books, migration , Paper recycling and end redistribution is explained
Chapter 8 Cell Structure and Function
It gives important inside and outside information about the major unit of life-head. Gives students detailed knowledge about cell discovery, its properties and structure. In ncert Chapter 8 Science Class 8, students are first told that the cell is the smallest living part of an organism. They will know that cells are of many types and many cells differ from organism to organism. The structure and function of the cell is beautifully explained. Different parts of the cell are described in full detail, in which the major part is the cell membrane, cytoplasm, nucleus. In this chapter concludes with a comparison of the cells of both plants and animals and their functions.
Chapter 9 breeding in animals
