NCERT Exemplar Class 8 Science Chapter 3: Synthetic Fibres and Plastics
NCERT Exemplar Solutions for Class 8 Science Chapter 3 – Synthetic Fibres and Plastics introduces students to man-made materials and their applications in modern life. The chapter begins with an explanation of synthetic fibres, classified into types such as rayon, nylon, polyester, and acrylic. Students learn about their properties like strength, elasticity, durability, and resistance to water, which make them widely used in textiles and industries. The chapter then highlights the advantages and disadvantages of synthetic fibres. While they are affordable, lightweight, and easy to maintain, they are not eco-friendly as they do not decompose easily and may cause environmental harm.
A major part of NCERT Solutions for Class 8 Science Chapter 3 is dedicated to plastics, where students learn about thermoplastics and thermosetting plastics, their uses in packaging, household goods, electronics, and industries. The harmful effects of plastic waste, its non-biodegradability, and the urgent need for plastic management and recycling are also explained. The chapter also includes the concept of biodegradable and non-biodegradable substances, helping students differentiate between eco-friendly and harmful materials. Another subtopic is the role of synthetic materials in reducing the use of natural resources like wood, cotton, and silk. By practicing NCERT Exemplar Solutions for Class 8 Science, learners gain clarity on fibre production, properties, and applications. They also develop awareness about the environmental issues linked with plastics and the importance of sustainable alternatives. NCERT Solutions for Class 8 Science ensure that students can answer application-based questions, relate scientific concepts to real-world scenarios, and become responsible users of synthetic materials.
