Understanding Class 6 Chemistry Worksheet On Chapter 4 Sorting Materials Into Groups Set 3
Class 6 Chemistry Worksheet On Chapter 4 Sorting Materials Into Groups Set 3 refers to the practice of organizing and classifying different items based on their similarities and differences. This worksheet covers the properties of materials such as appearance, hardness, solubility, flotation, transparency, and magnetic properties. Understanding sorting is important in areas like material classification, properties of substances, and grouping objects for scientific study.
Key Properties Used to Sort Materials
In sorting materials into groups, properties such as appearance (shiny or dull), hardness (hard or soft), roughness, solubility (soluble or insoluble in water), flotation (floats or sinks), transparency (transparent, translucent, opaque), magnetic properties, and conduction of heat are considered. Grouping similar things together makes finding, studying, and using them more efficient.
Here’s a helpful table to understand sorting materials better:
Sorting Materials Table
| Property | Description | Example |
|---|---|---|
| Lustre | Ability to reflect light (shine) | Gold, Silver |
| Hardness | Ability to resist compression or scratching | Stone, Iron, Wood |
| Solubility | Ability to dissolve in water | Salt (soluble), Sand (insoluble) |
| Flotation | Float or sink in water | Plastic ball (float), Iron nail (sink) |
| Transparency | Allows light to pass through or not | Glass (transparent), Cardboard (opaque) |
Worked Example – Material Grouping
Let’s understand the process step by step:
1. Choose objects: Wood block, Glass cup, Iron nail, Sponge.
2. Check for properties like hardness, transparency, flotation, magnetic response.
3. Group as per similarities—e.g., Wood and Sponge (float), Glass and Iron (sink).
4. Review and justify each group by explaining the property used.
Final Understanding: Using property-based grouping clarifies the nature of materials and builds scientific skills.
Practice Questions
- Define sorting materials into groups and give two examples.

Common Mistakes to Avoid
- Confusing sorting materials into groups with mixing materials.
- Using incorrect criteria for classification (for example, classifying by color when property-based sorting is required).
- Assuming all materials in a group share every property—some exceptions exist.

FAQs on Class 6 Chemistry Chapter 4 Sorting Materials Into Groups Worksheet Set 3
1. What is meant by sorting materials into groups in Class 6 Chemistry?
Sorting materials into groups means arranging objects based on their similar properties such as appearance, hardness, solubility, and transparency. In Class 6 Chemistry Chapter 4 – Sorting Materials Into Groups, materials are grouped to make their study easier and more systematic. For example:
- Metals are grouped together because they are usually hard and shiny.
- Liquids like water and oil are grouped based on whether they mix or not.
- Transparent materials like glass are grouped separately from opaque materials like wood.
2. Why do we need to classify or group materials?
We need to classify materials to make their study simple, organized, and systematic. Grouping helps us compare properties and understand differences easily. The main reasons are:
- To identify materials based on common properties.
- To select suitable materials for specific uses (e.g., plastic for insulation).
- To avoid confusion when studying a large number of substances.
3. What are the common properties used to sort materials into groups?
The common properties used to sort materials include appearance, hardness, solubility, floatation, transparency, and magnetism. These properties help in grouping substances effectively:
- Appearance – shiny or dull
- Hardness – hard or soft
- Solubility in water – soluble or insoluble
- Floatation – float or sink in water
- Transparency – transparent, translucent, or opaque
- Magnetism – attracted or not attracted by a magnet
4. What is the difference between transparent, translucent, and opaque materials?
The difference lies in how much light passes through the material.
- Transparent materials allow almost all light to pass through (e.g., clear glass, air).
- Translucent materials allow some light to pass but objects cannot be seen clearly (e.g., butter paper, frosted glass).
- Opaque materials do not allow light to pass through (e.g., wood, metal).
5. What is meant by soluble and insoluble substances in water?
A soluble substance dissolves in water, while an insoluble substance does not dissolve in water. For example:
- Salt (NaCl) and sugar dissolve in water, so they are soluble.
- Sand and chalk powder do not dissolve in water, so they are insoluble.
6. What is the difference between a solution and a suspension?
A solution is a clear mixture in which the solute completely dissolves, while a suspension is a mixture in which particles do not dissolve and settle down on standing.
- In a solution (e.g., salt in water), particles are not visible and do not settle.
- In a suspension (e.g., sand in water), particles are visible and settle at the bottom.
7. What does it mean if a material floats or sinks in water?
A material floats or sinks depending on its density compared to water.
- If a material is less dense than water, it floats (e.g., wood, cork).
- If a material is denser than water, it sinks (e.g., stone, iron nail).
8. How can we test whether a material is attracted to a magnet?
We can test magnetism by bringing a magnet close to the material and observing if it gets attracted.
- Materials like iron, nickel, and cobalt are magnetic.
- Materials like plastic, wood, and glass are non-magnetic.
9. What is the difference between hard and soft materials?
The difference between hard and soft materials is based on their ability to resist compression or scratching.
- Hard materials do not get compressed or scratched easily (e.g., iron, stone).
- Soft materials can be easily compressed or scratched (e.g., cotton, sponge).
10. Can a material be grouped in more than one way?
Yes, a material can be grouped in more than one way because it has multiple physical properties. For example:
- Iron is hard, opaque, and magnetic.
- Glass is hard, transparent, and non-magnetic.
