Quick Chapter Recap: Nature's Treasures

Chapter 11 of NCERT Class 6 Science introduces students to natural resources, which are materials and components found in the environment that are essential for human survival and development. The chapter categorises natural resources into renewable resources (like sunlight, wind, and water) that can be replenished naturally, and non-renewable resources (like coal, petroleum, and minerals) that exist in limited quantities and take millions of years to form. The chapter emphasises the need for judicious use and conservation of resources to ensure their availability for future generations. It also introduces the concept of pollution — contamination of air, water, and soil — and discusses how human activities contribute to environmental degradation. Students learn practical ways to conserve resources in daily life, such as reducing water wastage, saving electricity, reusing materials, and recycling waste. Understanding this chapter helps students appreciate the delicate balance of nature and their role in preserving it.

Natural resources are classified as renewable (sunlight, wind, water) and non-renewable (coal, petroleum, natural gas, minerals)
Conservation means using resources carefully and avoiding wastage to ensure availability for future generations
Pollution is caused by human activities like industries, vehicles, and improper waste disposal
The 3Rs — Reduce, Reuse, Recycle — are practical methods to conserve resources and reduce pollution
Sustainable development balances present needs with future resource availability

Long Answer Model Responses

The long-answer questions in Section E require detailed, structured responses that cover multiple aspects of each topic. Below are model answers that demonstrate the depth, organisation, and scientific accuracy expected in CBSE Class 6 Science exams. Each answer is approximately 80-100 words and uses proper paragraph structure or numbered points for clarity. When writing long answers, always begin by directly addressing the question, then systematically present your points with examples where relevant, and conclude with a brief summary if the question demands it. Practice writing these answers in your own words to develop your expression skills while retaining scientific accuracy. For HOTS questions like Q24, demonstrate your ability to connect cause and effect, predict consequences, and apply chapter concepts to hypothetical situations — this analytical thinking is crucial for higher grades.

Case-Study Answer Key

The case-study question tests your ability to analyse real-world situations using concepts from Nature's Treasures. Here are model answers for all three sub-questions. Notice how each answer identifies relevant information from the case study, connects it to chapter concepts, and provides clear, specific responses. When answering case studies, always refer to details given in the passage and support your answers with reasoning. This demonstrates comprehension and application skills that CBSE values highly. Case-study questions typically carry 6 marks in exams, so practice this format regularly. If you found this question challenging, re-read the chapter sections on water conservation and pollution, then attempt similar case studies to build confidence.

A24(a). Two reasons for water scarcity: (i) Excessive extraction of groundwater through borewells has lowered the water table significantly; (ii) Pollution of the local lake with sewage and plastic waste has made it unfit for drinking, reducing available water sources.
A24(b). Two steps to reduce water consumption: (i) Take shorter showers or use a bucket instead of running water while bathing; (ii) Reuse water from washing vegetables or rinsing utensils for watering plants or cleaning.
A24(c). Long-term measures: (i) Implement rainwater harvesting systems across the city to recharge groundwater and reduce dependence on borewells; (ii) Set up sewage treatment plants to clean wastewater before releasing it into water bodies; (iii) Launch awareness campaigns about reducing water wastage and penalise industries that pollute; (iv) Restore the lake by removing plastic waste and preventing further sewage discharge.
