### Class 6 Science Chapter 4 Sorting Materials Into Groups

• 4.1 Objects Around Us

NCERT Solutions for Class 6th Science Chapter 4 words to assess the previous knowledge of the students regarding the objects which surround us. The lesson mainly wants to explain how to sort them into groups. Students also learn in the section how to sort out the objects into several groups. The NCERT solutions of Vedantu emphasize the methods and principles of sorting several objects. It makes students understand more about the objects. If an object appears, then they can easily find out that a particular object belongs to which category.

Two activities are given to the students to get practical knowledge about the objects and the material used to get those objects by the NCERT Solutions of Science Class 6 Chapter 4 PDF.

• 4.2: Properties of Materials

In this section of Chapter 4, the students can learn the several properties of materials because the objects need to categorize or sort out into the groups by using their properties. The objects which are having say properties are categorized into a single group. The NCERT Solutions of Class 6 Science Chapter 4 majorly concentrates on the objects and their materials, their properties, and purposes too.

Since without having prior knowledge of the purpose of the item, we should not use the appropriate material to manufacture it. Class 6 Chapter 4 Science has explained the concept of properties using a simple example which can be understandable by the grade 6 students.

### Appearance

CBSE Class 6 Science Chapter 4 talks to the students to learn the first property by which we can categorize the objects easily. it is a visible property called appearance. The NCERT Solutions of Vedantu provided several examples to find how to classify objects through appearance like wood, iron, steel, plastic, etc. Along with the explanation part, the students are given and engaged with the activity to collect different kinds of objects based on their appearance.

### Hardness

NCERT solutions Class 6 Science ch 4 is using the sense organs as a priority to sort out the objects into groups. Coming to the next property in this chapter, it is the hardness of the object. The students can easily understand this by touching the object itself. Because if we touch the wooden object, it will be hard whereas if we touch the object made of cloth or rubber, it is soft. Based on these also, the students can sort out the objects into groups.

### Soluble or Insoluble

As the students are involved in learning various properties of objects in this fourth chapter of Class 6 Science prepared by NCERT Solutions of Vedantu, the next significant property is about solubility. Students will collect a few items and test them by mixing each one in a glass of water. If it is dissolved, then it is called a solution, and if it is not dissolved, it is called nonsolution.

### Objects may Float or Sink

Students need to pay more attention here. But the NCERT Solutions of Class 6 Science had tried a lot to explain the difference between these two properties and the method of using photo property to the students.

### Transparency

NCERT Solutions Class 6 Science Chapter 4 sorting materials into groups and she gets the students to learn about both transparent materials and opaque materials in this last section of the chapter.

### Exercises

• Match the following.

• 8 True or false.

• Grouping activities.

## FAQs on NCERT Solutions for Class 6 Science Chapter 4 - Sorting Materials Into Groups

1. What is an object? What are its properties?

An object is a combination or collection of the matter who discovered physical and chemical properties. The basic physical properties of an object are,

• Transparency

• Appearance

• Hard ness

• Float or sinker

• Solubility

2. What are the chemical properties of an object?

Along with the physical properties, every object has some typical properties. If you take an object when it changes the state of matter to another state by any reaction, then it is termed as chemical property, and the reaction is known as a chemical reaction. Some of the chemical properties of an object are,

• Acidity

• Reactivity

• Combustion

• Condensation

• Flammability

• Evaporation etc.

3. How do we sort different materials?

Materials are classified based on similarities and variations in their characteristics. Things are grouped together for ease of use and to better understand their characteristics. These similarities further have their own subgroups. This helps to sort them into even more similar groups, in an efficient manner. This is how we tend to sort different materials together.

4. What does the property of a material signify?

The physical characteristics of a substance describe the physical condition of material apart from its chemical or mechanical components. These characteristics include texture, density, mass, melting and boiling points, as well as electrical and thermal conductivity. Different materials can be sorted into different groups based on their varying properties, be it physical or chemical. Sorting materials is necessary and useful.

5. What does one mean by physical properties?

A physical property is the property of a material that can be viewed or quantified without affecting the substance's identity. Colour, density, hardness, and melting and boiling points are examples of physical characteristics. The physical properties of multiple materials are unique to that material and are very useful for sorting the materials into different groups. Hence knowing about any material’s physical properties can be helpful.

6. What does one mean by chemical properties?

A chemical property is a quality of a specific material that may be seen during a chemical reaction. Some of the most important chemical characteristics include flammability, toxicity, enthalpy of formation, pH value, oxidation states and chemical stability. These are very crucial as they provide information about any product's properties and can also be helpful in sorting materials based on their chemical properties.

7. Why is sorting necessary in Class 6?

Organizing things into groups allows us to organize them in a methodical manner. When things are grouped, they are easier to manage. When objects are grouped, it is much easier to get an idea about their varying properties. It is also easier to compare two items when they are grouped. Hence, sorting or grouping can be really helpful and can help in identifying similar materials based on their physical or chemical attributes.
