FAQs for RBSE Class 6 Science Chapter 2
1. Why is grouping materials important?
Grouping materials helps in understanding their properties, making it easier to select the right material for the right purpose.
2. Can materials be sorted based on more than one property?
- Yes, materials can be classified based on multiple properties such as color, texture, and solubility.
3. What are the examples of conductors and non-conductors?
- Conductors: Metals like copper, aluminum.
- Non-conductors (Insulators): Plastic, rubber, wood.
4. How can students test if a material is transparent?
- To test for transparency, students can try to look through the material to see if light passes through it clearly.
5. What is the difference between transparent, translucent, and opaque materials?
- Transparent materials allow full light passage, translucent materials allow partial light, and opaque materials block light completely.
