Questions
Passage 1:
Read the given passage below and answer the questions:
On a winter sunday afternoon, Ruchi and her friends collected different items from their houses. They collected sugar, salt, mustard oil, sand, sawdust, honey, chalk powder, soil, glucose and wheat flour. They tried to mix each of the materials into water and observed certain changes. Some of them were soluble, and some were not soluble in water. Certain materials were floating on the surface of water and few of them sank into the bottom. They also classified the items on the basis of appearance that is hard and soft. They recorded all their observations in the notebook.
Q. 1. Items which dissolve in water are called __________.
(a) Soluble
(b) Insoluble
(c) Mixer
(d) Soft
Difficulty Level: Easy
Ans. Option (a) is correct.
Explanation: Items that dissolve in water are called soluble. They mix uniformly with water, forming a solution. In contrast, insoluble items do not dissolve and remain separate.
Q. 2. Which of the following is/are hard on the basis of appearance:
(a) Honey
(b) Mustard oil
(c) Sand
(d) Both a and b
Difficulty Level: Easy
Ans. Option (c) is correct.
Explanation: Honey and mustard oil soft in appearance and touch. But sand is hard and rough in touch and appearance.
Q. 3. Consider the following statements about sugar:
(A) It is soluble in water.
(B) It is opaque in nature.
(B) It is lustrous.
(C) It is made up of metal.
Difficulty Level: Medium
The correct statements are:
(a) (A) and (B)
(b) (B) and (C)
(c) (C) and (D)
(d) (A), (B) and (D)
Ans. Option (a) is correct.
Explanation: Sugar can easily be dissolved in water. It is opaque and hard. It is made up of element carbon, hydrogen and oxygen.
Q. 4. Why do all liquids not dissolve in water?
Difficulty Level: Difficult
Ans. Some liquids do not dissolve in water and form a separate layer when kept aside for some time. Two liquids must have the same polarity to be dissolve. Oil does not dissolve in water because oil is nonpolar, whereas water is polar.

Learning Objectives
- To identification and classification of various objects based on their composition and properties, like shape, colour, texture and transparency.
- Analysis and comparison of hardness, solubility of different materials through hands-on activities and experimentation.
- Understanding the significance of material properties in selecting suitable materials for making objects.
- Understanding the matter.
Materials are substances or mixtures of substances that make up objects in our everyday environment. Everything we see and touch is composed of one or more materials.
Understanding materials helps us comprehend the physical world around us. All things are made up of some materials. The material from which an object is made affects its durability, functionality and aesthetic appeal. This understanding also influences the selection of materials for various uses.
Matter is anything that occupies space and has mass. It can be classified into different types based on its properties.
Keywords Related to Materials Around Us
- Lustrous: Shiny or reflective surface, often seen in metals like gold and silver.
- Volume: The amount of space occupied by a substance or object, measured in cubic units.
- Transparent: A material that allows light to pass through so objects behind can be seen clearly.
- Translucent: A material that allows some light to pass through but scatters it, making objects appear blurry.
- Soluble: A substance that can dissolve in a solvent, like salt in water.
- Soft: A material that can be easily compressed, bent, or cut, like rubber or cotton.
- Hard: A material resistant to deformation, scratching, or cutting, like steel or diamond.
- Insoluble: A substance that does not dissolve in a solvent, like sand in water.
- Material: Any substance used to create or build things, including wood, metal, or plastic.
- Matter: Anything that has mass and occupies space.
- Mass: The amount of matter in an object, measured in kilograms or grams.
