NCERT Class 6 Science Chapter 4 Sorting Materials Into Groups Topic-Wise Discussion

Here’s a topic-wise discussion for NCERT Class 6 Science Chapter 4:

4.1 Things Around Us

NCERT Solutions for Class 6th Science Chapter 4 aim to assess what students already know about the things that are around us. The lesson primarily aims to show how to group these things. Students also learn how to organise things into different groups in this section. PhysicsWallah’s NCERT solutions highlight the methods and principles of sorting various things, helping students better understand them. When a thing is present, they can easily determine which category it belongs to.

4.2: Characteristics of Materials

In this part of Chapter 4, students can learn about the different characteristics of materials because things need to be categorised based on their characteristics. Things with similar characteristics are placed in a single group. Class 6 Science Chapter 4 NCERT Solutions mainly focus on things, their materials, their characteristics, and their purposes.

Without prior knowledge of the purpose of an item, we should not use the appropriate material to make it. Chapter 4 of Class 6 Science explains the concept of characteristics using a simple example that can be understood by sixth-grade students.

In CBSE Class 6 Science Chapter 4, students are encouraged to understand the first characteristic that helps in easily grouping objects – appearance. This visible trait, as explained in PhysicsWallah’s NCERT Solutions, includes examples like wood, iron, steel, plastic, etc. Students are also involved in activities where they collect various objects based on their appearance.

NCERT Solutions for Class 6 Science Chapter 4 prioritise the use of sense organs to categorise objects. Moving on to the next characteristic, it is the hardness of the object. Students can comprehend this by simply touching the object. For instance, wood feels hard, while objects made of cloth or rubber feel soft. Using this understanding, students can group objects accordingly.

Soluble or Insoluble

As students explore different object properties in Chapter 4 of Class 6 Science using PhysicsWallah’s NCERT Solutions, another important aspect is solubility. The chapter guides students to test items by mixing them in water. If an item dissolves, it’s termed a solution, and if it doesn’t, it’s considered a nonsolution.

Objects may Float or Sink

This part requires careful attention from students, and the NCERT Solutions of Class 6 Science make efforts to clarify the distinction between these two properties. The chapter also introduces a visual aid method using photos to help students understand this concept.

Transparency

In NCERT Solutions for Class 6 Science Chapter 4, which focuses on sorting materials into groups, the last section enlightens students about transparent and opaque materials.

NCERT Solutions for Class 6 Science Chapter 4 FAQs

An object is a tangible item with mass and volume. Its properties include characteristics like colour, shape, size, and texture.

The chemical properties of an object refer to its behaviour in chemical reactions, such as reactivity with acids, flammability, and corrosion resistance.

Different materials can be sorted based on their physical properties, like density, hardness, and conductivity, or by their chemical properties, such as reactivity with specific substances.

The property of a material signifies its inherent characteristics, which can be either physical (e.g., density, melting point) or chemical (e.g., reactivity, combustibility).

Physical properties are inherent characteristics of a material that can be observed or measured without changing its chemical composition, such as colour, density, and conductivity.

Chemical properties describe how a substance interacts with other substances, including its reactivity, flammability, and ability to undergo chemical reactions.

Short Type Questions and Answers

Question 1. What are herbs?

Answer: The small plants with soft/tender, green, short stem are called herbs. Herbs hardly attain height more than 1.5 metres. Their stems are not woody and can be bent. A herb may or may not have branches, e.g., tomato, mint, paddy, etc.

Question 2. Write the differences between a shrub and a tree, based on the properties of the stem. Answer:

Question 3. From the members of the various groups given below, find the odd one out.

Coriander (dhania), mint (pudina), jamun, grass.
Rose, mehndi, guava, morepankh.
Jamun (Jamun is a tree while others are herbs).
Guava (Guava is a tree while others are shrubs).

Question 4. What are climbers and creepers? Give some examples.

Answer: In some plants like grape vines, money plant, bean stalk, gourd plants, etc., the stem is so weak that it cannot hold it straight. They either stand up with some support or they just spread on the ground. In the first condition, the plants are called climbers and in second condition, they are called creepers or runners.

Question 7. Pitcher plant has green leaves which can prepare food by photosynthesis then why does it eat insects?

Answer: Pitcher plant eats insects to get nitrogenous compounds which it neither synthesizes nor can absorb from the soil.

Question 8. What are weeds?

Answer: The unwanted plants that grow in the field with the main crops or in their surroundings are called weeds. Weeds are the plants which are not grown by the farmers, e.g., grass.

Question 9. What is a stem?

Answer: The part of the plant which generally grows above the ground level and bears leaves, flowers and fruits is called a stem.

Question 10. Do you agree that stem is like a two way street?

Answer: Yes. Stem carries the water absorbed by the roots to the leaves and also the food prepared by the leaves to the roots

Question 11. What are the modification of stem?

Answer: Stem is modified to perform certain special functions:

Storage of food
Storage of water
Provide support
To make food
Multiplication or reproduction.

Question 12. What are nodes and internodes?

Answer: Nodes: The point where the leaf arises on the stem. They are attached to the stem by a stalk. Internodes: The portion of the stem between the two nodes.

Question 13. Define petiole and lamina.

Answer: The part of leaf which is attached to the stem is called petiole and the broad green part of the leaf is called lamina.

Question 14. What are veins?

Answer: There are some lines on the leaf called veins.

Question 15. What is midrib?

Answer: There is a thick vein in the middle of the leaf called midrib.

Question 16. Why are leaves generally green?

Answer: The green colour of leaves is because of the presence of chlorophyll.

Question 17. What are the modifications seen in a pitcher plant?

Answer: In a pitcher plant, the lamina is modified into a pitcher and apex into its lid.

Question 18. What are lateral roots?

Answer: The smaller roots that grow on the main taproot are called lateral roots.

Question 19. How do you identify the root system of a plant without pulling it out of soil?

Answer: By looking at the venation of the leaves, we can identify the root system of a plants. Plants with leaves having parallel venation have fibrous root and leaves having reticulate venation have taproot.

Question 20. What is a fruit? How does it differ from a seed?

Answer: After fertilization, the ovary of the flower gets stimulated by the action of seed and forms the fruits, like mango, orange, etc. Embryo surrounded by a hard wall is called the seed.

Question 21. Write the functions of sepals and petals.

Answer: Functions of sepals: Sepals protect the inner parts of flower when it is a bud. Function of petals: Petals attract the insects which are the agencies of pollination by colour and fragrance.

Question 22. In what sequence does a plant bear? Seed, Flower, Fruit.

Answer: A plant bears first flowers, then seeds and in the last fruits.

Question 23. Write the names of reproductive parts of a flower.

Answer: The reproductive parts of a flower are:

Question 24. What do you mean by a complete and an incomplete flower?

Answer: The flower with all whorls, i.e., sepals, petals, stamen and carpel in it is a complete flower. If anyone of these is absent in a flower, it is called an incomplete flower.

Long Type Questions and Answers

Question 1. Do all flowers have four separate whorls? Does any flower have more than four whorls? If so, write its name.

Answer: No. Some flowers have some additional whorls than others. Sometimes some of these whorls may even be absent. For example:

In Gudhal, an additional whorl of epicalyx is found.
In unisexual flowers, either stamen or pistil is absent.

Question 2. Do all flowers have the same parts and are they arranged in the same way?

Answer: The flowers of different species of plants are different. The number of petals and sepals are different in different flowers. Some of the flowers have stamens and some flowers have only pistil, others have both. Sepals may be connected with petals in some cases; but in other cases, these may be separated. Thus, the properties of flowers are different.

Question 3. Why roots are modified?

Answer: Certain plants have modified roots to perform specific functions:

Storage roots, e.g., carrot, radish
Supporting roots, e.g., banyan, rubber
Climbing roots, e.g., money plant
Parasitic roots, e.g., dodder
Breathing roots, e.g., mangroves.

Question 4. Explain the difference between taproots and fibrous roots.

Question 5. What are the main functions of roots?

Answer: Main functions of roots are:

Roots absorb water and minerals from soil for the other parts of the plants.
Roots hold the plant firmly to the soil.
Some roots transform to store food, e.g., radish.
Roots of leguminous plants contain symbiotic bacteria which add the fertility of soil by fixing atmospheric nitrogen into nitrates.

Question 6. What do you mean by

leaf venation
reticulate venation, and
parallel venation?
Leaf venation: The design made by veins in a leaf is called leaf venation.
Reticulate venation: If the design is net-like on both sides of midrib, the venation is called reticulate venation.
Parallel venation: In the leaves of grass, the veins are parallel to one another. This is called parallel venation.

Question 7. Explain the main functions of leaf.

Answer: There are following two main functions of leaf:

Transpiration: The extra water comes out of the leaves through stomata in the form of vapour. This process is called transpiration.
Photosynthesis: The process by which leaves prepare their food from water and carbon dioxide in the presence of sunlight and a green-coloured substance i.e., chlorophyll is called photosynthesis.

CBSE Case Study Questions Class 6 Science The Living Organisms Characteristics and Habitats

Case study 1.

In the sea, plants and animals aresurrounded by saline (salty) water. Mostof them use the air dissolved in water.There is very little water available inthe desert. It is very hot in the day timeand very cold at night in the desert. Theanimals and plants of the desert live onthe desert soil and breathe air from thesurroundings.The sea and the desert are verydifferent surroundings and we find verydifferent kind of plants and animals inthese two region. Let us lookat two very different kind of organismsfrom the desert and the sea – a cameland a fish. The body structure of a camelhelps it to survive in desert conditions.Camels have long legs which help to keep their bodies away from the heat of the sand. They excrete small amount of urine, their dung is dry and they do not sweat. Since camels losevery little water from their bodies, theycan live for many days without water.

Let us look at different kinds of fish.The thing that is common in all fishis their streamlined shape, which helps them move inside water. Fish have slippery scales on their bodies. These scales protect the fish and also help in easy movement through water. Fish have flat fins and tails that help them to change directions and keep their body balance in water. Gills present in the fish help them to use oxygen dissolved in water.

Que. 5) Answer: Fish have slippery scales on their bodies. These scales protect the fish and also help in easy movement through water.

Case study 2

The place where organisms live iscalled habitat. Habitat means a dwellingplace (a home). The habitat provides food, water, air, shelter and other needsto organisms. Several kinds of plants and animals live in the same habitat.The plants and animals that live onland are said to live in terrestrialhabitats. Some examples of terrestrialhabitats are forests, grasslands, deserts,coastal and mountain regions. On theother hand, the habitats of plants and animals that live in water are called aquatic habitats. Lakes, rivers and oceans are some examples of aquatic habitats. There are large variations among terrestrial habitats like forests, grasslands, deserts, coastal and mountain regions located in different parts of the world.

The organisms, both plants and animals, living in a habitat are its biotic components. The non-living things such as rocks, soil, air and water in the habitat constitute its abiotic components.

On the other hand, the habitats of plants and animals that live in water are called aquatic habitats. Lakes, rivers and oceans are some examples of aquatic habitats.

Case study 3

Abiotic factors likeair, water, light and heat are importantfor the growth of plants. In fact, abioticfactors are important for all livingorganisms.We find that organisms exist in verycold as well as very hot climates, this is becausethey manage to survive through adaptation.

Adaptation is the method by whichorganisms get well adjusted to the climate. Adaptation does not take place in a short time because the abiotic factors of a region also change very slowly. Those organisms which cannot adapt to these changes die, and only the adapted ones survive. Organisms adapt to different Abiotic factors in different ways. This results in a wide variety of organisms in different habitats.

Que.1) Adaptation can happen in a short span of time.

Que.2) Which of the following is NOT an Abiotic factor?

a) Human beings

Que.3) …………………………………………………………………………………… helps organisms to exist in extreme climates.

a) Abiotic components

b) Habitats

c) Adaptation

d) None of the above

Que.4) Define the term Adaptation?

Que.5) Briefly explain how adaptation takes place?

Que.1. b) False

Que.2. a) Human beings

Que.3. c) Adaptation

Que.4) Answer: Adaptation is the method by which organisms get well adjusted to the climate.

Que.5) Answer: Adaptation does not take place in a short time because the abiotic factors of a region also change very slowly. Those organisms which cannot adapt to these changes die, and only the adapted ones survive. Organisms adapt to different Abiotic factors in different ways. This results in a wide variety of organisms in different habitats.

Case study 4

There are desert animals like ratsand snakes, which do not have long legsthat a camel has. To stay away from the intense heat during the day, they stayin burrows deep in the sand. These animals come out only during thenight, when it is cooler. Desert plants lose very little water through transpiration. The leaves in Desert plants are either absent, very Small, or they are in the form of spines. This helps in reducing loss of water from the leaves through transpiration. The Leaf-like structure you see in a cactus is, in fact, its stem. Photosynthesis in these plants is usually carried out by the stems.

Mountain habitats are normally very cold and windy. In some areas, snowfall may take place in winters. Here, Trees are normally cone shaped and have sloping branches. The leaves of some of these trees are needle-like. This helps the rainwater and snow to Slide off easily. Animals living in the mountain regions are also adapted to the conditions there. They have thick skin or fur to protect them from cold. For example, yaks have long hair to keep them warm. Snow leopard has thick fur on its body including feet and toes. This protects its feet from the cold when it walks on the snow.

Que. 1) Photosynthesis in desert plants is carried out through it’s ………………………………………………………………………………….…… .

Case study 5

Apart from fish, many other Sea animals have streamlined bodies to help them move easily in water. There are some sea animals like squids and octopus, which do not have this streamlined shape. They stay deeper in the ocean, near the seabed and catch any prey that moves towards them. However, when they move in water they make their body shapes streamlined. These animals have gills to help them use oxygen dissolved in water. There are some sea animals like dolphins and whales that do not have gills. They breathe in air through nostrils or blowholes that are located on the upper parts of their heads. This allows them to breathe in air when they swim near the surface of water. They can stay inside the water for a long time without breathing. They come out to the surface from time to time, to breathe in air.

Plants growing in ponds, lakes and rivers have their roots fixed in the soil below the water. In terrestrial plants, roots normally play a very important role in the absorption of nutrients and water from the soil. However, in aquatic plants, roots are much reduced in size and their main function is to hold the plant in place. The stems of these plants are long, hollow and light. The stems grow up to the surface of water while the leaves and flowers, float on the surface of water. Some aquatic plants are submerged in water. All parts of such plants are under water. Some of these plants have narrow and thin ribbon-like leaves. These can bend in the flowing water.

Que.5) Answer: In terrestrial plants, roots normally play a very important role in the absorption of nutrients and water from the soil. However, in aquatic plants, roots are much reduced in size and their main function is to hold the plant in place.

Case study 6

When we inhale, the air moves from outside to the inside of our body. When we breathe out, the air moves from inside our body to outside. Breathing is part of a process called respiration. In respiration, some of the oxygen of the air we breathe in, is used by the body. We breathe out carbon dioxide produced in this process. The process of breathing in animals like cows, buffaloes, dogs or cats is similar to humans. Respiration is necessary for all livingorganisms. It is through respiration that the body finally obtains energy from thefood it takes.Some animals may have different mechanisms for the exchange of gases,which is a part of the respiration process. For example, earthworms breathethrough their skin. Fishhave gills for using oxygen dissolved inwater. The gills absorb oxygen from theair dissolved in water. Respiration also takes place in plants. Exchange of gases in plants mainly takes place through leaves. The leaves take in air through tiny pores in them and use the oxygen. They give out carbon dioxide to the air. The amount of oxygen released in the process of food preparation by plants is much more than the oxygen they use in respiration.

Changes in our surroundings that makes us respond to them, are called stimuli. All living beings respond to stimuli, including plants. Flowers of some plants bloom only at night. In some plants flowers close after sunset. In some plants like Mimosa, commonly known as ‘touch-me-not’, leaves close or fold when someone touches them. These are some examples of responses of plants towards changes in their surroundings.

Que.1) Respiration in ………………………………………………………………………… takes place through their skin.

b) Earthworms

Que.2) During photosynthesis, the amount of …………………………………………………………………………….……… released by plants is much more than it uses during Respiration?

b) Carbon dioxide

Que.3) The leaves of mimosa or touch me not plant closes or folds, when someone touches them?

Que.4) Define the term respiration?

Que.5) Explain the process of Respiration in plants?

Que.1. b) Earthworms

Que.2. a) Oxygen

Que.4) Answer: Breathing is part of a process called respiration. In respiration, some of the oxygen of the air we breathe in, is used by the body. We breathe out carbon dioxide produced in this process.

Que.5) Answer: Exchange of gases in plants mainly takes place through leaves. The leaves take in air through tiny pores in them and use the oxygen. They give out carbon dioxide to the air. The amount of oxygen released in the process of food preparation by plants is much more than the oxygen they use in respiration.

Case study 7

All organisms need food. Not all thefood that is eaten is completely used,only a part of it is utilised by the body. The rest has tobe removed from the body as wastes. Ourbody produces some wastes in other lifeprocesses also. The process of gettingrid of wastes by organisms is known asexcretion. Plants also excrete. They do, butnot as seen in animals. The mechanismsin plants are a little different. Some plantsfind it possible to store the waste productswithin their parts in a way that they donot harm the plant as a whole. Someplants remove waste products assecretions.Excretion is another characteristiccommon to all organisms.

Animals reproduce their own kind. The mode of reproduction may be Different, in different animals. Some Animals produce their young ones through eggs. Some animals give birth to the young ones. Plants also reproduce. Like animals, Plants also differ in their mode of Reproduction. Many plants reproduce through seeds. Plants produce seeds, which can germinate and grow into new plant. Some plants also reproduce through parts other than seeds. For example, a part of a potato with a bud, grows into a new plant. Plants also reproduce through cuttings. Living things produce more of their own kind through reproduction.

Que.1) Only a part of food is required by our body and the rest is removed through secretion.

Que.2) Which of the following is a mode of Reproduction in plants?

c) Cuttings

Que.3) Living things produce their own kind through the process of …………………………………………………………………………………………… .

b)Respiration

c) Reproduction

d) Secretion

Que.4) Define the term Excretion?

Que.5) Explain the process of excretion in plants?

Que.2. d) All of the above

Que.3. c) Reproduction

Que.4) Answer: The process of getting rid of wastes by organisms is known as excretion.

Que.5) Answer: Plants also excrete. They do, but not as seen in animals. The mechanisms in plants are a little different. Some plants find it possible to store the waste products within their parts in a way that they do not harm the plant as a whole. Some plants remove waste products as secretions.

NCERT Solutions for Class 6 Science Chapter 4 Sorting Materials into Groups 2

Metal: It is a hard, shiny, usually solid material which is able to be shaped and can conduct or allow electricity and heat to pass through it.
Transparency: Light can pass through certain objects. Due to this, we are able to see through the objects. This property of materials to allow light to pass through them and enable visibility is called transparency. On this basis, objects can be of three types:

i. Transparent: If almost all the light can pass through an object, it is called transparent. We can see clearly through transparent materials such as air, water and a clear glass. ii. Opaque: If no light can pass through an object, it is called opaque. We cannot see through an opaque material at all, such as cardboard, milk, stone and metal. iii. Translucent: If light can pass through an object partially, it is called translucent. We cannot clearly see through a translucent material such as a frosted glass, turbid water and dust-laden air. Such materials allow partial visibility.

Objective: To distinguish between transparent, opaque and translucent materials. Materials Required: Apiece of a clear glass, a cardboard, oily paper and torch. Procedure:

Take a torch and point it to each of the three objects-a clear glass, a cardboard and oily paper one by one.
Write down what happens when light is pointed to each of the objects.

NCERT Solutions for Class 6 Science Chapter 4 Sorting Materials into Groups 3

Rough or Smooth: An object having an uneven or irregular surface is said to be rough, such as sandpaper. On the other hand, object having a smooth and levelled or a polished surface is said to be smooth. For example, mirror and metals.
Floatation: Many materials float, whereas many others sink in water. This property is called floatation. Materials such as wool, leaves and feathers float on the water whereas rocks and metals sink.
Density: The mass per unit volume of a substance is known as its density. Materials which are less dense than water float on it. Materials denser than water sink in it.

Objective: To classify different materials on the basis of floatation. Materials Required: Wooden piece, dry leaf, pebble, eraser, iron nail, pencil, table tennis ball and a bucket half-filled with water. Procedure:

Take all these materials at a time and drop them in the bucket of water.
Observe whether each material float on water or sink to the bottom of the bucket.

NCERT Solutions for Class 6 Science Chapter 4 Sorting Materials into Groups 4

Materials can also be grouped on the basis of whether the object is solid, liquid or gas, whether it is conductor of heat or it is a non-conductor of heat. For example, metals are conductors of heat but wood and plastics are non-conductors of heat.

Need to Group Materials: We group materials due to the following uses:

Sorting of materials into groups makes it convenient for us to view them.
We can store similar things together and hence can locate them easily.
Dividing materials into groups makes it convenient to study their properties and the patterns in these properties.

Class 6 Science Chapter 4 Sorting Materials into Groups Additional Important Questions and Answers

Short Answer Type Questions

Question 1. Why is a tumbler not made with a piece of cloth? Answer: We use tumblers made of glass, plastic and metal to keep a liquid. These substances can hold a liquid. A tumbler made of cloth cannot hold a liquid because:

cloth piece is not hard enough to hold liquids, and
cloth piece has very minute pores through which the liquid oozes out.

Question 2. Make a table and state whether the following materials mix with water or not. Vinegar, lemon juice, mustard oil, coconut oil and kerosene. Answer:

Question 3. Name five objects each which can be made from the following materials: wood, cotton, leather, paper Answer:

Question 4. Metals generally occur in solid state and are hard in form. Name a metal that exists in liquid state and a metal that is soft and can be cut with knife. Answer: Mercury is a metal that exists in liquid state. Sodium and Potassium are soft metals and can be cut with knife.

Question 5. Why do we cook food in utensils made of aluminium or other metallic materials? Answer: Cooking utensils which are used to cook food are made from aluminium or other metals. The reason is that metals are good conductors of heat. They allow the transmission of heat through them and food cooks quickly. Therefore, utensils are made of metals.

Question 6. Universal solvent (water) is very essential for the human body. Why? Answer: The universal solvent is able to dissolve a number of substances. So it is essential for the human body. It constitutes a major part of the cells located in human body. All materials are transported across the body in dissolved form.

Question 7. Classify the following into transparent, translucent and opaque materials. Butter paper, cardboard, ground glass, clear glass, water, air, brick, wall, aluminium sheet Answer: Transparent: Clear glass, water, air Translucent: Butter paper, ground glass Opaque: Cardboard, brick, wall, aluminium sheet

Question 8. Classify the following into hard materials and soft materials. Cotton, iron, diamond, chalk, wood, wax, clay, sponge, bone, feathers Answer: Hard materials: Iron, diamond, wood, bone, chalk Soft materials: Cotton, wax, clay, sponge, feathers

Question 9. Write three common characteristics of materials. Answer:

All materials can be felt by one or more of our senses.
All materials occupy space.
All materials possess mass.

Question 10. Write a short note on texture. Answer: Materials may be rough or smooth. The surface of paper or a glass tumbler feels smooth since there are no uneven surfaces. The bark of tree, rock and sandpaper are rough to touch because their surfaces are uneven and bumpy. So, materials can be classified on the basis of their texture.

Question 11. Write a short note on floatation. Answer: Many materials float, whereas many others sink in water. This property is called floatation. Materials such as wood, leaves and feathers float on the water whereas rocks and metals sink. If you weigh equal volumes of cotton and water, the cotton weigh less than water as cotton is less dense than water.

Long Answer Type Questions

Question 1. What is classification? How is it useful? Explain with examples. Answer: The method of grouping objects on the basis of certain similarities and dissimilarities is called classification. We can understand the importance of classification with the help of simple examples.

a. The things in your house are the most common examples. You classify or group them while arranging them. You keep the utensils in the kitchen, the books in the study room and the bed in the bedroom. It helps in locating the things easily.

b. Classification also enables us to make a systematic study of anything. For example, if you observe the way things have been stocked in your kitchen, you will find that various items are classified. Certain items are classified as spices and stocked together.

Other items may be required for a common activity, say, making a tea. Hence, these are stocked together. You also classify your items and arrange your study table in such a way that you do not have to waste time trying to locate a given item.

Question 2. Define solubility of materials in water. Give examples. Answer: Some materials are soluble in water whereas some are insoluble. For example, sugar is soluble in water whereas sand is insoluble. Actually, water causes all molecules in a solid piece of sugar to break apart. The individual molecules, when separated, are so small that we cannot see them. We can say that sugar is soluble in water. Some solids like sugar and common salt are soluble in water.

On the other hand, sand is insoluble in water. It settles down in water and does not dissolve even on stirring. Some solids are insoluble in water, e.g., wood, stone, chalk and wax. Materials in each state can therefore be classified on the basis of their solubility in water.

Question 3. Define the properties of matter. Answer: Some important properties of matter are discussed below:

Appearance: Materials can be classified on the basis of their appearance. Different materials have different appearance.
Lustre: Materials can be classified on the basis of their lustre or shine. Some shine a lot whereas others are quite dull.
Texture: Different materials feel different when touched, so they have different textures. Some can be rough and others can be smooth.
State: Most materials can be placed into one of the three states: solid, liquid or gas.
Solubility in water: Some materials are soluble in water whereas some are insoluble. Miscible liquids mix with each other while immiscible liquids do not.
Transparency: If almost all the light can pass through an object, it is called transparent. If no light can pass through an object, it is called opaque. If light can pass through an object partially, it is called translucent.
