Sorting Materials into Groups

Introduction to Sorting Materials into Groups

What is Sorting?

Sorting is any method of organising objects in a systematic order, and it has two separate meanings: putting objects in a logical order based on some criterion; Categorising is the process of grouping objects that have comparable characteristics.

Any substance or mixture of substances with a volume and mass is referred to as a material. In most cases, a substance refers to a pure chemical. A material’s appearance, behaviour, name, structure, colour, order, composition, and any other information about it are all characteristics. We’ve observed that our food and clothing come in such a variety of styles. There is such a wide range of items everywhere, not only food and clothing. 

It is easier to analyse materials characteristics when they’re divided into categories. It also aids in the detection of any patterns in these characteristics. For example, we may quickly identify related things by grouping them together. It’s easier to analyse materials’ characteristics and look for trends in their properties when they’re divided into groups.

Why Do We Need to Sort Materials into Groups?

The characteristics of materials are classified together based on their similarities and contrasts. Materials are grouped together for ease of use and research purposes. We save time, energy, and make our work simpler by grouping items.

Organising things by grouping them makes it easier to arrange them in a specific order. When things are grouped together, they are much easier to manage. When objects are grouped, it is much easier to understand their attributes. It’s also easier to compare two items when they’re grouped together.

Purpose of Sorting Materials into Groups

Classification is the process of classifying and grouping objects/things based on certain criteria. It simplifies, organises, and facilitates the study of a huge number of items of various types. Materials come in a variety of shapes and sizes, each with its own set of characteristics. They distinguish things based on similarities and differences while sorting them. The youngsters compare objects to see if one has more or less of a certain attribute. Sorting and classifying exercises help youngsters develop a variety of cognitive abilities and lay the groundwork for subsequent problem-solving.

Advantages of Sorting Materials into Groups

1. Storage

Sorting things into solid, liquid, and gas categories is required in order to designate appropriate containers for storage. Vegetables, for example, can be transported in canvas bags, but milk and oil are not. Oil and milk can be stored in open-mouth containers like a glass tumbler, but gases like nitrogen and oxygen cannot.

2. Manufacturing 

An object’s substance may be determined based on its properties. For example, if we want to make liquid-storage bottles, we utilise materials like glass, plastic, or metal, but we can’t use fabric or leaves since they won’t hold the liquid. Similarly, we may use wood or plastic to make cricket bats, but we cannot use glass.

3. Disposal 

Sorting items into groups of biodegradable and non-biodegradable substances is critical for proper disposal. Dry and moist trash for degradable chemicals should also be segregated to ensure a longer decay time during transit. To decrease the waste of non-biodegradable materials, the items should be separated into recyclable and non-recyclable categories.

4. Usage 

We must classify substances based on their physical and chemical characteristics in order to make good use of them. Lemon juice and tamarind, for example, may be used as souring agents in the kitchen, but sugar cannot.

Properties of Materials

Any substance or mixture of substances with a volume and mass is referred to as a material. Some things can be produced from different materials, such as plastic, while others, such as a table and chair made of wood, can be made from the same material. A material’s property is a physical attribute of a material that is independent of the amount of the substance in question.

Based on the physical properties of materials, the classification of materials are given below. 

1. Appearance

The appearance of materials can be used to distinguish them from one another. Other materials, such as graphite and wood, do not appear to be glossy and are referred to as non-lustrous. Metals include shiny objects like iron, gold, and copper that are found in nature.

Colour, borders, font, transparency, and other parameters are controlled via the Appearance object’s attributes. Glossy materials are referred to as lustrous, whereas quasi materials are referred to as non-lustrous.

2. Transparency

Transparent materials include air, water, and clear glass. When light collides with transparent materials, nearly all of it goes straight through. All visible light passes through glass. Translucent items enable a little amount of light to pass through. Any incident light is reflected or absorbed by opaque materials. Light rays cannot travel through opaque materials as a result materials, such as wood and stone, are opaque.

3. Hardness

Hardness is a material’s resistance to localised plastic deformation. Hardness is only one mechanical property to consider; other qualities like toughness and strength must also be taken into account, as hard materials have poor toughness and are readily broken.

Hard materials are materials that cannot be readily crushed, chopped, deformed, or scraped. Iron and glass are two examples. Soft materials are materials that can be compressed. Cotton, rubber, and sponge are among examples.
