The NCERT Exemplar Solutions for Class 6 Science provide comprehensive answers to all questions from the NCERT Exemplar textbook, designed specifically to help students build strong conceptual foundations. These solutions cover all twelve chapters including Components of Food, Sorting Materials into Groups, and Electricity and Circuits, addressing common difficulties students face such as distinguishing between conductors and insulators or understanding the difference between transparent and translucent materials. Each solution is structured to develop problem-solving abilities and critical thinking skills essential for competitive exams. Students often struggle with application-based questions in topics like Separation of Substances, where they must identify the appropriate method for different mixtures. The detailed step-by-step explanations help clarify why handpicking works for larger impurities while sedimentation is better for heavier particles. EduRev offers these solutions in a convenient format that allows students to practice chapter-wise and track their progress systematically, making science learning both engaging and effective for Class 6 students.
This chapter explores the origin of various food items we consume daily, helping students understand that all food ultimately comes from plants and animals. Students learn to classify food sources into plant-based and animal-based categories, identifying specific plant parts like roots, stems, leaves, fruits, and seeds that provide nutrition. The chapter addresses common misconceptions, such as students often not realizing that honey comes from nectar collected by bees or that mushrooms are neither plants nor animals but fungi.
This chapter introduces students to the six major nutrients-carbohydrates, proteins, fats, vitamins, minerals, and dietary fiber-along with the importance of water in our diet. Students learn simple tests to identify the presence of starch, proteins, and fats in food samples, a practical application that often appears in school practicals. A common challenge students face is remembering which nutrient deficiency causes which disease; for instance, confusing kwashiorkor (protein deficiency) with marasmus (overall calorie deficiency) or not understanding that night blindness results from Vitamin A deficiency.
This chapter teaches students to classify materials based on observable properties like appearance, hardness, solubility, transparency, and ability to float or sink. Students learn why grouping objects makes it easier to study their properties and locate them efficiently. A specific difficulty students encounter is distinguishing between translucent and transparent materials-many incorrectly classify frosted glass as opaque rather than translucent because objects appear blurred through it. The chapter also explores how the same material can have different properties in different forms, such as how paper is flexible but cardboard is rigid.
This chapter covers various methods of separating mixtures including handpicking, threshing, winnowing, sieving, sedimentation, decantation, filtration, and evaporation. Students learn to select the appropriate separation method based on the properties of components in a mixture-a skill that requires understanding the physical basis of each technique. A common error students make is suggesting filtration for separating miscible liquids or not recognizing that sedimentation works only when one component is heavier and insoluble. The chapter includes real-world applications like how salt is obtained from seawater through evaporation.
This chapter introduces plant morphology, focusing on the structure and functions of roots, stems, leaves, flowers, fruits, and seeds. Students learn to differentiate between taproot and fibrous root systems, and understand leaf venation patterns in monocots versus dicots. A specific challenge students face is identifying whether a plant part is a modified stem or root-for example, mistaking potato (a stem tuber) for a root or not recognizing that onion is a modified stem. The chapter also covers the parts of a flower and their reproductive functions.
This chapter explores how humans and animals move, introducing the skeletal and muscular systems. Students learn about different types of joints-ball-and-socket, hinge, pivot, and fixed-and understand which movements each joint allows. A common misconception is that students often think bones can move on their own without understanding that muscles contract and relax to produce movement. The chapter also compares human movement with how earthworms, snails, cockroaches, birds, fish, and snakes move, highlighting the diversity of locomotion strategies in the animal kingdom.
This chapter defines the characteristics of living organisms-movement, growth, reproduction, respiration, response to stimuli, excretion, and nutrition-and explores how organisms adapt to their habitats. Students learn about different biomes including deserts, mountains, grasslands, and aquatic environments. A specific difficulty is understanding adaptations: students often struggle to explain why camels have long eyelashes (to protect eyes from sand) or why mountain goats have strong hooves (for grip on rocky surfaces). The chapter distinguishes between terrestrial, aquatic, and aerial habitats with examples of organisms uniquely suited to each environment.
This chapter introduces the concept of motion and various units of measurement for length and distance. Students learn about standard units (meter, kilometer, centimeter) and the importance of having uniform units for accurate measurement. A common challenge is converting between units-students often make errors when converting kilometers to meters or centimeters to meters by misplacing decimal points. The chapter also covers different types of motion including rectilinear, circular, and periodic motion, with everyday examples like a moving car, a spinning top, and a swinging pendulum to illustrate each type.
This chapter explores the properties of light, explaining how light travels in straight lines and how shadows are formed. Students learn about transparent, translucent, and opaque objects, and understand why shadows change in size and shape depending on the position of the light source. A specific concept students struggle with is understanding why shadows are always formed on the opposite side of the light source or why a shadow has the same shape as the object but not necessarily the same size. The chapter also introduces reflection and the characteristics of images formed by plane mirrors.
This chapter introduces basic concepts of electricity, including electric cells, bulbs, circuits, conductors, and insulators. Students learn to construct simple circuits and understand why a circuit must be complete for a bulb to light up. A common practical error is that students often leave gaps in the circuit or use insulators like plastic to connect components, then wonder why the bulb doesn't glow. The chapter teaches students to identify conductors (metals like copper and aluminum) versus insulators (rubber, wood, plastic) through simple experiments, building foundational knowledge for understanding electrical safety.
This chapter explores the properties of magnets, including attraction, repulsion, magnetic and non-magnetic materials, and the directional property of magnets. Students learn that magnets have two poles-north and south-and that like poles repel while unlike poles attract. A specific misconception students have is believing that magnets attract all metals, when in fact only ferromagnetic materials like iron, nickel, and cobalt are attracted to magnets, while copper and aluminum are not. The chapter also covers how to make magnets and the use of magnets in compasses for finding directions.
This chapter discusses the composition of air, explaining that air is a mixture of gases including nitrogen, oxygen, carbon dioxide, and water vapor. Students learn about the properties of air-it occupies space, has mass, exerts pressure, and supports combustion through oxygen. A common experimental challenge is demonstrating that air occupies space: students often don't understand why water doesn't enter an inverted glass pushed into a container unless the glass is tilted. The chapter also covers how oxygen is essential for respiration and combustion, and how carbon dioxide is used by plants during photosynthesis.
NCERT Exemplar Solutions for Class 6 Science are specifically designed to challenge students beyond the standard NCERT textbook questions, incorporating higher-order thinking problems that develop analytical skills. These solutions are particularly valuable because they address conceptual questions, numerical problems, and diagram-based queries that frequently appear in school examinations and scholarship tests. Students preparing for competitive exams like NTSE or Science Olympiads benefit significantly from practicing these problems, as they bridge the gap between basic understanding and advanced application. EduRev provides complete chapter-wise solutions that help students identify and overcome their weak areas systematically. For instance, students who find difficulty in understanding circuits can revisit the Electricity chapter solutions to understand series versus parallel connections through detailed explanations and circuit diagrams.
The NCERT Exemplar problem book for Class 6 Science contains carefully curated questions that test conceptual clarity and application ability across all topics in the syllabus. Unlike regular textbook questions that focus on recall, Exemplar questions require students to apply concepts to new situations-for example, predicting which separation method would work for a novel mixture or explaining why certain animals can survive in extreme habitats. These solutions help students develop scientific temperament by encouraging them to think logically about cause-and-effect relationships in natural phenomena. Students who consistently practice these Exemplar Solutions typically perform better in school exams because they develop deeper understanding rather than superficial memorization of facts and definitions.
