Materials Around Us Class 6 Short questions and answers
Question: What is a material?
Answer: A material is any substance used to create an object. Examples include paper, wood, cloth, glass, metal, plastic, and clay.
Question: Why do we classify materials?
Answer: We classify materials to organize them based on common properties such as shape, color, hardness, and the materials they are made of, making it easier to study and understand their characteristics.
Question: Give an example of a lustrous material.
Answer: An example of a lustrous material is metal, such as iron, copper, or aluminum. These materials have shiny surfaces.
Question: What is the difference between transparent, translucent, and opaque materials?
Answer: Transparent materials allow objects to be seen clearly through them (e.g., glass). Translucent materials allow objects to be seen but not clearly (e.g., frosted glass). Opaque materials do not allow objects to be seen through them (e.g., wood).
Question: What properties are used to choose a material for making an object?
Answer: The choice of material for making an object depends on its properties, such as the ability to hold water, durability, appearance, and the purpose for which the object will be used.
Question: What happens when you mix sugar and water?
Answer: When sugar is mixed with water, it dissolves completely, making the water taste sweet. Sugar is soluble in water.
Question: How can you tell if a material is hard or soft?
Answer: A material is hard if it is difficult to compress or scratch, like a stone. A material is soft if it can be easily compressed or scratched, like an eraser.
Question: What do mass and volume tell us about matter?
Answer: Mass tells us the quantity of matter in an object, while volume tells us the space occupied by that matter. Anything that has mass and occupies space is considered matter.
Question: Why do we use different materials for different parts of an object like a pen?
Answer: We use different materials for different parts of an object to match the material’s properties with the required function, such as using metal for durability and plastic for lightweight design.
Question: How can you classify the balls used in sports?
Answer: Balls used in sports can be classified based on their size, color, texture, and how high they bounce, which are determined by the materials they are made of.
Question: What is the process of classifying objects into groups called?
Answer: The process of classifying objects into groups based on similar properties is called classification.
Question: Name two examples of materials that are soluble in water.
Answer: Sugar and salt are examples of materials that are soluble in water.
Question: Why are some metals non-lustrous?
Answer: Some metals become non-lustrous due to the effect of air and moisture, which causes their surfaces to become dull.
Question: Give two examples of opaque materials.
Answer: Examples of opaque materials include wood and metal.
Question: What is terracotta, and how is it made?
Answer: Terracotta is baked clay used to make pots and other items. It is made by shaping clay and then baking it in kilns.
Question: How do you determine if a material is soft?
