NCERT Solutions for Class 6 Science Chapter 6 Material Around Us (Exercises and Questions)

Chapter 6 important questions and answers are given below. These NCERT Solutions for Class 6 Science Chapter 6 will help you a lot in your exams.

Question 1. Visit your kitchen and observe how your parents have organised various edibles. Can you suggest a better sorting method? Write it in your notebook

Answer:

In my house kitchen, different items are stored in different containers of shelves. Different cereals like Rice and wheat are stored in different containers at the topmost shelf of the almirah, while spices are arranged in small containers and are placed at the middle shelf. Packed products and snacks are arranged in the different cabinets of the almirah. Fruits, milk and vegetables are kept in the refrigerator.

Sorting method:

We can arrange items based on their types and usage frequency.

• Daily use items like sugar, salt, etc can be arranged in one compartment
• Rarely used items like special types of masalas can be arranged in different compartments
• Pulses and grains can be arranged in one cabinet.
• Ready-to-eat and snacks can be arranged in a separate cabinet
• Fruits and vegetables can be store in a Refrigerator

Arranging all these items in a systematic way can reduce hustle and confusion and kitchen work can be done more quickly and easily.

Question 2: Unscramble the letters (Column I) and match with their properties (Column II)

Unscramble letters in column I

Answer:

(i)- (b)

(ii)-(d)

(iii)-(a)

(iv)-(c)

Question 3: The containers that are used to store materials in shops and at home are usually transparent. Give your reasons for this.

Answer:

Usually, transparent containers are used in shops and at home because in transparent containers we can see the content inside it without opening it. Transparent containers save time and effort by quickly identifying what is inside the container and transparent containers also help to maintain hygiene because to identify things, we don't need to open them again and again which prevents exposure to sunlight, moisture and dust.

Question 4: State whether the statements given below are True [T] or False [F]. Correct the False statement(s).

(i) Wood is translucent while glass is opaque.

Answer: False

Correct statement: Wood is opaque while glass is translucent.

(ii) Aluminium foil has lustre while an eraser does not.

Answer: True

(iii) Sugar dissolves in water, whereas sawdust does not.

Answer: . True

(iv) An apple is a matter because it occupies no space and has mass.

Answer: False

Correct statement: An apple is a matter because it occupies space and has mass

Question 5: We see chairs made up of various materials, such as wood, iron, plastic, bamboo, cement and stones. The following are some desirable properties of materials that can be used to make chairs. Which materials used to make chairs fulfil these properties the most?

(i) Hardness (does not bend or shake on sitting, even after long use).

(ii) Lightweight (easy to lift or to take from one place to another).

(iii) Does not feel very cold when sitting during winters.

(iv) Can be cleaned regularly and made to look new even after long use

Answer:

(i). Hardness (does not bend or shake on sitting even after long use)

Iron and steel are very strong and durable and they can easily wear heavy weight without bending.

(ii) Lightweight (easy to lift or to take from one place to another).

Plastic and Bamboo are lightweight and they are easy to move and can be taken from one place to another easily.

(iii) Does not feel very cold when sitting during winter.

Wood and Bamboo do not feel very cold when sitting during winter

(iv) Can be cleaned regularly and made to look new even after long use

Plastic and iron are good for this purpose because they can be cleaned regularly and made to look new by painting iron chairs even after long use.

From here we concluded that any single material fulfills all the properties but if we consider comfort, usability and maintenance then plastic, wood and bamboo chairs are best.

Question 6: You need to have containers for the collection of: (i) food waste, (ii) broken glass and (iii) wastepaper. Which materials will you choose for containers of these types of waste? What properties of materials do you need to think of?

Answer:

To choose the ideal container for the things given above we shall consider the nature of the things and the material used to make the container:

(i) Food waste: For food waste, we can use either plastic or stainless steel containers because they are easy to clean and durable.

(ii). Broken glasses: Metal or thick plastic containers can be used for broken glasses because they are strong and safe to handle sharp objects like broken glass.

(iii) Wastepaper: For these, we can use plastic baskets, wooden and cardboard baskets because wastepaper is light and can be easily placed in plastic, wooden and cardboard containers.

Some important properties of containers :

• Containers are durable
• They are strong and water-resistant
• Containers are easy to clean
• Ensures safety by containing sharp objects

Question 7: 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:

(i) transparent, opaque

(ii) translucent, transparent

(iii) opaque, translucent

(iv) transparent, translucent

Answer:

The correct answer is option (i). Transparent, opaque

Air is transparent, and the wooden door is opaque.

Air allows light to pass through it completely, while wooden doors do not allow light to pass through it.

Question 8: 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.

Answer:

In the above problem, it is clearly mentioned that material X is rigid and does not change its shape easily but it is soluble in water, while material Y can change shape easily and doesn't dissolve in water. Hence, Material X is hard and soluble, while Material Y is soft and insoluble.

Question 9: (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?’

Answer (i):

(a). Metal example: steel

(b). Rubber and air

(c). Sugar

(d). Opaque object like wood

(e). Air

Answer (ii):

I am hard

You can see through me clearly

Used in making utensils, I am strong and shiny

I am non-lustrous

Question 10: 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. Now, make two pairs of materials where one material remains insoluble in the other material

Answer:
