FAQs on CBSE Class 6 Science Important Questions Chapter 6 - Materials Around Us
1. What are the most important types of materials discussed in Class 6 Science Chapter 6?
The important types of materials include metals (like iron, aluminium), wood, glass, plastic, rubber, and fabric. Each type has unique properties, such as hardness, flexibility, and solubility, which make them suitable for specific uses as per CBSE 2025–26 curriculum.
2. What are the properties of materials that are frequently asked in CBSE Class 6 Science important questions?
- Hardness – Ability to resist scratching or compression
- Transparency – Allows light to pass through
- Flexibility – Can bend without breaking
- Solubility – Ability to dissolve in water
- Conductivity – Ability to conduct heat or electricity
3. How are materials classified in exam-oriented CBSE Class 6 important questions?
Materials are classified based on properties like hardness (hard/soft), transparency (transparent/opaque/translucent), solubility (soluble/insoluble), and conductivity (conductors/insulators), which is a key exam concept as per latest marking scheme.
4. Why are metals often considered important in frequently asked questions for construction materials? (HOTS)
Metals like iron and aluminium are important in construction because they are strong, durable, and weather-resistant, making them ideal for building safe and lasting structures (as per CBSE 2025–26 exam trends).
5. What is a common exam pitfall when identifying transparent, opaque, and translucent materials? (FUQ)
The main pitfall is confusing translucent materials (partly allow light, like frosted glass) with transparent (clear, like plain glass) and opaque (no light, e.g., wood). Remember: Objects behind translucent materials appear blurred, not invisible.
6. How can a student distinguish between conductors and insulators in exam questions? (Application)
- Conductors: Materials that let electricity or heat pass through easily (e.g., metals like copper, aluminium)
- Insulators: Materials that block electricity or heat (e.g., rubber, plastic)
7. Why is plastic preferred for making water bottles as per important CBSE questions?
Plastic is often used for water bottles because it is lightweight, durable, and does not react with water, ensuring safety and convenience. This is a classic 2-mark question in CBSE exams.
8. Compare the environmental impact of biodegradable and non-biodegradable materials. (FUQ, HOTS)
- Biodegradable materials decompose naturally and do not accumulate in the environment (e.g., paper, wood)
- Non-biodegradable materials such as plastic persist, contributing to pollution and environmental harm. This is critical for both HOTS and application questions in 2025–26 pattern.
9. How does understanding material properties support better choices in daily life? (FUQ, Application)
Understanding material properties helps students select the right materials for specific purposes, encourages use of sustainable options, and reduces waste—topics that often appear in value-based or application-focused exam questions.
10. What is the process called when materials are arranged based on their properties?
The process is termed classification of materials and is a key concept in exam questions for Class 6 Science, as per CBSE marking guidelines.
11. What types of questions on solubility and transparency can be expected in 3-mark sections? (Exam strategy)
Students may be asked to classify given materials (like salt, sand, glass) based on whether they dissolve in water and/or allow light through. Correct tabular answers, as per CBSE patterns, fetch full marks.
12. Why can’t a tumbler made of cloth be used for storing water? (HOTS)
A cloth tumbler is not suitable because cloth is porous (lets water pass through) and not rigid, so it cannot hold water without leaking or collapsing. This reasoned answer matches CBSE requirements for High Order Thinking Skills questions.
13. What are conceptual traps students face when classifying materials by hardness? (FUQ)
Common traps include:
- Assuming all metals are equally hard (e.g., gold is softer than iron)
- Not testing for scratch or compression resistance accurately
- Forgetting that some plastics can be hard or soft
14. How are grouping and classification of materials relevant in real-life situations? (FUQ)
Grouping helps in choosing suitable materials for a task, understanding material uses, recycling, and waste management. For example, separating plastic and paper aids in better recycling. Such real-life linked questions are scoring in CBSE exams.
15. Explain why gold and silver remain shiny while iron rusts. (Application, HOTS)
Gold and silver maintain their shine because they are less reactive and don’t corrode easily. In contrast, iron reacts with air and moisture, forming rust that dulls its surface—an important property-related question for Class 6 Science exams.
