CLASS 6 SCIENCE · CHAPTER 11
These notes follow the chapter’s sequence and explain its central ideas, examples and activities. Read each section, connect it with the textbook observations, and use the quick check to review the main concepts.
Air, water, sunlight, forests, soil, rocks and minerals are among the treasures of nature described in the chapter. Living beings depend on these resources for survival and for many daily activities. Fresh air supports breathing, water is used for drinking and growing plants, and soil supports plant growth. Nature provides food and shelter to organisms, while sunlight is an important source of energy. These resources are connected: changing one part of an environment can affect other parts as well.
Air is all around us even though we cannot usually see it. Breathing shows how important air is to living beings; holding one’s breath quickly becomes uncomfortable, so breathing activities should be performed safely and without holding the breath for a long time. Water is needed for drinking, washing, cooking, gardening and many other activities. The chapter asks students to consider how water is used at home and how it can be conserved. Careful use reduces waste and supports the needs of people and other living things.
Sunlight supports life on Earth and provides energy that people use in different ways. Plants use sunlight as they grow, and sunlight also warms the Earth. Thinking about the Sun as a natural resource helps connect daily life with wider natural processes. Using energy thoughtfully and avoiding unnecessary waste are ways to respect resources. The chapter’s examples encourage students to identify where natural resources are present in objects and activities they encounter each day.
Forests provide habitats, food and shelter for many organisms and contribute to the well-being of the environment. Soil supports plant growth and contains materials needed by plants; its properties influence what can grow in a place. Rocks and minerals are natural materials used in many ways. These resources take part in connected systems, so damaging forests or soil can have consequences beyond one location. Protecting natural areas and using materials responsibly helps preserve these benefits.
Fossil fuels are resources formed over very long periods and are not replaced on a human timescale. This is why they are described as non-renewable. Renewable resources can be replenished naturally on a shorter timescale, although responsible use is still important. The chapter distinguishes renewable and non-renewable resources and asks students to consider the resources used in everyday products. Conserving resources, reducing waste and choosing carefully can help ensure that nature’s treasures remain available for future needs.
Key idea: Air, water, sunlight, forests, soil, rocks and minerals are among the treasures of nature described in the chapter.
