Through this blog, you will learn Class 6 Science Chapter 2 and know what objects are and how many types there are. The answers to all the questions of Class 6 Science Chapter 2 are also given below.
We have seen many types of food and clothes around us. Apart from this, we have also seen many types of objects like phones, chairs, table coolers, freeze, stones, toys, books, water, etc. in the shape of all objects. The color and usage are different.
Look at the things around you and identify the things that are round-shaped. Make a list of them, this round-shaped object can be any object like a rubber, ball, drug or football. It can also contain round-shaped fruits and vegetables.
Just as the Earth takes things made of iron from us. iron ball, bearing ball, pipe chairs, and many other things. All of these are made of iron, but their shapes and sizes are different, similarly, there are also plastic vases which are made in different sizes, colors, and shapes.
Thus, most of the things around us are made up of one or more materials. These materials can be of any form like soil, paper, wood, metals, plastic, and glass.
1. Question Answer Class 6 Science Chapter 2
Are All Objects Made from the Same Type of Material?
All objects, no matter what shape or form they are, are made up of different materials.
Name Five Objects Made of Wood.
chair, table, bed, bat, and wickets.
What Are the Names of Five Things Made of Plastic?
Ball, chair, stool, bucket, jug. etc
Name Five Objects Made of Iron.
Chair, machines, rod, pipes, and tap.
Properties of Metal
Did you know that we do not make household utensils from cloth but from metal and plastic materials? Why don’t we make utensils from cloth? We do not want to make the vessel out of cloth because if liquid is added to it, it will boil and if we cook food in a cloth vessel, the cloth will burn before us or our food will not be cooked.
If we have to keep only water, we can use plastic, glass etc. pots, but if we have to keep hot food or any hot item, we have to choose metal utensils.
2. Question Answer Class 6 Science Chapter 2
What Type of Vessel Should Be Used to Keep Hot Food?
We should use utensils made of metal to keep hot food, because due to high melting point the food will not melt quickly.
What Type of Vessel Is Required to Store Water (Liquid)?
We prefer to use plastic and metal vessels to store water because they are more flammable than cloth.
appearance
All materials appear completely different from each other. Plastic looks different from iron. Iron looks different from gold and silver. However, there is some similarity between gold and iron which plastic does not have.
- Shining: All metals have shine. But plastic is not a metal so it does not shine.
- Ductile: All metals are ductile. But non-metals are not ductile.
- Luster: all metals have luster.non metal have no lustre.
- Hardness: all metals are hard but all non-metal are not hard.
3. Question Answer Class 6 Science Chapter 2
What is Soft Material?
Material: A material that can be easily compressed scraped and used is called soft material. example: rubber, cotton.
What Is Hard Material?
Hard: A material that cannot be easily compressed or scratched so that it can be used is called soft material. example: iron, brass,
- Soluble: When a substance dissolves completely in water, it is called a water-soluble stone. example: salt, sugar.
- soluble: When any substance which does not dissolve completely in water is called an insoluble substance. example: sand, pebble.
Water has a very important role in our lives because it dissolves a large amount of impurities and substances in our bodies
Do All Liquids Dissolve in Water?
Not all liquids dissolve in water. Oil does not mix in water.
Do All Gases Dissolve in Water?
Not all gases dissolve in water but oxygen dissolves in water, which plays an important role in the survival of all living beings.
Why Do We Need to Group Material?
Things are grouped together so that we could understand their properties easily.
.
- Transparent: Such a substance or material that can be seen through and used again is called transparent. example: air, water, and glass.
- Opaque: The material that cannot be seen through the eyes is called opaque material. example: iron box, wooden box, plastic box cardboard, etc.
- Translucent: A material that cannot be seen again and again is called translucent material. example: oily paper, some glass.
