NCERT Solutions Class 6 Science Chapter 6 - Materials Around Us

Beginning Class 6 Science can be fun, and perhaps a little intimidating, and that is precisely where the NCERT Solutions for Chapter 6: Materials Around Us fits in – it is designed to enhance this learning component and make it easier and clearer for young minds to engage with the wonderful world of science.

Science is ultimately a process for making meaning of our world: what is our world made up of, and why do things happen the way they do? It is an empirical process of observation, experimentation, and evidence. Science is a means for teaching us how to be curious, how to ask questions, and how to use logical reasoning – all of which take us far beyond the classroom.

The NCERT Solutions for Class 6 Science Chapter 6 will support students in developing a strong scaffolding in making sense of the scope of materials in the world around them, but, more importantly, keep them curious about how the world works. Once students reach this point, where they are beginning to not think of science as a subject, but instead are looking at the world with wonder, clarity, and critical thinking, then progress is being made in this journey of understanding.

2.0Key Concepts in Chapter 6: Materials Around Us

In the NCERT textbook, particularly in Class 6 Science, the chapter "Materials Around Us" typically introduces students to the basics of identifying, classifying, and understanding the properties of various materials encountered in everyday life.

World of Materials Introduction: This chapter opens by explaining what materials are and how they are essential components of everything around us, promoting natural curiosity in students.

Diversity of Materials: It introduces students to the vast variety of materials, from natural to man-made, and how they differ in their appearance and properties.

Properties of Materials: The chapter illustrates the importance of understanding the properties of materials through examples, such as:

• Appearance (Lustre): Whether a material is shiny or dull.
• Hardness: How easily a material can be compressed or scratched.
• Solubility: Whether a material dissolves in water or not.
• Transparency: Whether a material is transparent, translucent, or opaque.
• Float or Sink: Whether a material floats or sinks in water.

Grouping Materials: The correct answer illustrates the importance of grouping materials based on their properties, which helps in understanding their uses and behavior.

Inculcating Scientific Temperament: The chapter guides students to inculcate a scientific temper (Scientific Temperament) consisting of:

1. Observation and questioning.
2. Logical reasoning and critical analysis.
3. An evidence-based way of thinking about things.

Real-life Examples: The chapter is based on real-life examples to help students understand scientific concepts, using real-life incidents and scenarios that students can relate to, from simple daily life examples for Class 6 such as identifying materials used to make a chair or a glass.

Here are some common subtopics covered in this chapter:

• Introduction to Materials
• • What are materials?
  • Importance of materials in our daily life
• Diversity of Materials
• • Examples of different materials (wood, plastic, metal, glass, paper, fabric, etc.)
  • Natural vs. man-made materials
• Properties of Materials
• • Appearance (Lustre): Shiny vs. dull
  • Hardness: Hard vs. soft
  • Texture: Smooth vs. rough
  • Solubility: Soluble vs. insoluble in water
  • Transparency: Transparent, translucent, opaque materials
  • Float or Sink: Materials that float or sink in water
  • Magnetic Properties (sometimes introduced): Materials attracted to magnets
• Grouping Materials Together
• • Why do we group materials?
  • Methods of grouping based on properties
• Uses of Materials
• • How material properties determine their uses
  • Examples of objects made from different materials and why
• Simple Experiments with Materials
• • Hands-on activities to test properties like solubility or whether an object floats/sinks

Ans. (1)-(b), (2)-(d), (3)-(a), (4)-(c)

• The containers which are used to store materials in shops and at home are usually transparent. Give your reasons for this. Ans. The containers which are used to store materials in shops and at home are usually transparent because keeping the things in transparent jars so it can be seen easily, and customers attracted to see them.
• State whether the statements given below are True [T] or False [F]. Correct the False statement(s). (a) Wood is translucent while glass is opaque. (b) Aluminium foil has lustre while an eraser does not. (c) Sugar dissolves in water whereas sawdust does not. (d) An apple is a matter because it occupies no space and has mass. Ans. (a) [False] Wood is opaque while glass is transparent. (b) [True] (c) [True] (d) [False] An apple is a matter because it occupies space and has mass.
• We see chairs made up of various materials, such as wood, iron, plastic, bamboo, cement and stones. Following are some desirable properties of materials which can be used to make chairs. Which materials used to make chairs fulfil these properties the most? (a) Hardness (does not bend or shake on sitting even after long use). (b) Lightweight (easy to lift or to take from one place to another) (c) Does not feel very cold when sitting during winters. (d) Can be cleaned regularly and made to look new even after long use. Ans. (a) iron, cement and stone (b) Plastic and bamboo (c) Wood, bamboo (d) Cement and stone
• You need to have containers for collection of (a) food waste, (b) broken glass and (c) wastepaper Which materials will you choose for containers of these types of waste? What properties of materials do you need to think of? Ans. Plastic is suitable to store, food waste, broken glass and waste paper. because plastic is non reactive and light in weight and will not break easily.
• Air is all around us but does not hinder us from seeing each other. Whereas, if a wooden door comes in between, we cannot see each other. It is because air is $\_\_\_\_$ and the wooden door is $\_\_\_\_$ . Choose the most appropriate option: (a) transparent, opaque (b) translucent, transparent (c) opaque, translucent (d) transparent, translucent Ans. transparent, opaque
• Imagine you have two mysterious materials, X and Y . When you try to press material X, it feels rigid and does not change its shape easily. On the other hand, material Y easily changes its shape when you press it. Now, when you mix both materials in water, only material X dissolves completely. while material Y remains unchanged. What can materials X and Y be? Can you identify whether material X is hard or soft? What about material Y? Justify your answer. Ans. Material X could be salt or sugar (hard and soluble in water). Material Y could be rubber (soft and insoluble in water). Material X is hard because it does not change shape easily and dissolves in water. Material Y is soft because it changes shape easily and does not dissolve in water.
• (i) Who am I? Identify me on the basis of the given properties. (a) I have lustre. $\_\_\_\_$ (b) I can be easily compressed. $\_\_\_\_$ (c) I am hard and soluble in water $\_\_\_\_$ (d) You cannot see clearly through me $\_\_\_\_$ (e) I have mass and volume but you cannot see me. $\_\_\_\_$ (ii) Make your own 'Who am I?' (a) I am soft and insoluble in water $\_\_\_\_$ (b) I am hard and have a shiny surface (c) I can be easily compressed and I am used for cleaning $\_\_\_\_$ Ans. (i) (a) metal (b) sponge (c) salt (d) Translucent (e) Air (ii) (a) Clay (b) Metal (c) Sponge
• You are provided with the following materials - vinegar, honey, mustard oil, water, glucose and wheat flour. Make any two pairs of materials where one material is soluble in the other.
