VR Tour For Std. 6 Ch. 4: Sorting Materials into Groups

What's Included in Virtual tour of this chapter

Sorting is the process of arranging items with similar properties by grouping them.  We are surrounded by various objects which have different shapes like spherical, cylindrical, cone, and cuboid. Further, in our virtual tour, we will identify the objects according to their surfaces and sort them into groups. Some objects have a Shiny surface while some objects have a dull surface. We will sort solid and liquid substances based on solubility. Some substances are soluble in water while some do not dissolve into water. Further in the chapter, we will understand why some objects float on water while some sink with an experiment. The final virtual tour will focus on identifying transparent, opaque, and translucent objects.

Virtual tour 1 Sorting materials according to their shape

Virtual tour 1: Sorting materials according to their shape

We will learn how to sort objects in accordance with their shapes. Each shape will have a slightly different dimension and size. You will be able to identify shapes like Sphere, cuboid, cylindrical, cone, and circle. In day-to-day lives, we are surrounded by so many different shapes. With this virtual tour, we have learned what kind of shapes the objects are in.  Materials that cannot be easily compressed, cut, bent, or scratched are called hard materials.

Virtual tour 2 Sorting materials according to their surface

Virtual tour 2: Sorting materials according to their surface

There are a number of objects in this world and those are made of different types of materials. It is because of the different kinds of surfaces they have. We will sort the objects into two groups – Dull and Shiny. A dull or dead surface has a rough base or slightly roughened surface whereas a Shiny surface is a smooth and glossy surface.

Virtual tour 3 Sorting materials according to their hardness

Virtual tour 3: Sorting materials according to their hardness

The Materials that can be compressed, cut, or scratched easily are called soft materials while the materials that are difficult to compress, cut, or scratched are called hard materials. We will perform a little experiment with cream, iron nail, wax, butter, ice-cream, and ball, and learn the difference between hard and soft objects.

Virtual tour 5 Sorting Liquids according to their solubility in water

Virtual tour 4: Sorting solid materials according to their solubility in water

In this virtual tour, we will sort solid things based on their solubility. Solubility means the ability of any substance to dissolve in water. Substances that dissolve in water are called soluble and substances that do not dissolve in water are called insoluble.

Virtual tour 5: Sorting Liquids according to their solubility in water

All substances on the earth have their definite density. Density means the relation of the weight of a substance to its size. Based on this property, the objects either float or sink in the water. The object which is denser than water will sink whereas the object which is less dense than water, will float.

Virtual tour 6: Sorting materials according to their density

After collecting the cotton, let’s move to the second stage in this virtual tour.  We will first separate the cotton fibers from cotton seeds. The cleaned cotton is sent to the second plant, where it is compressed and its bundles are sent for spinning. Spinning is the process of producing yarns from the extracted fibers. We will learn in this process how the strands of cotton fibers are twisted together to form yarn.

Virtual tour 7 Transparent, translucent and opaque objects

Virtual tour 7: Transparent, translucent and opaque objects

In this final virtual tour, we will sort the object on the basis of their transparency, translucent and Opaque. Transparent objects are the ones where we can see through the object clearly. The translucent object is less than completely transparent but clear enough to allow the passage of light whereas the opaque objects are the ones through which we cannot see anything.
