VR Tour For Std. 6 Ch. 6: Changes around Us

What's Included in Virtual tour of this chapter

We will learn about reversible and irreversible changes. When a certain substance changes by a certain process and if we can get back the original form of the substance, such a process is called a reversible change. Similarly, the changes that cannot be reversed are called irreversible changes. We will also learn how buds converting into flowers is an irreversible change, while expansion and contraction of the iron ring is a reversible change.

Virtual tour 1: Information about Reversible and Irreversible changes and its examples

So, this learning virtual tour is based on “Change”. Can we change everything around us? No, but there are certain things which we can change like can you get the salt back which you have dissolved in water? The answer is yes. We will go through this virtual tour with a lot of experiments. Such changes are called reversible changes. Can you make chapati with dough? Yes, you can. But can you get the dough back from the chapatti? No, therefore such changes are called irreversible changes.

Virtual tour 2 Reversible and Irreversible changes Part 2

Virtual tour 2: Reversible and Irreversible changes Part 2

In this virtual tour, We will see the concept of reversible and irreversible change more clearly. We will perform fun activities with balloons, little doll made of ceramic, plastic, etc. If you inflate a balloon, you can get it back to its original shape but if you burst a balloon, you cannot get it back to its original shape.

Virtual tour 3 Reversible and Irreversible changes Part 3

Virtual tour 3: Reversible and Irreversible changes Part 3

To have a deep insight into the concept, we will go to a garden. Is it possible to convert the flower back to a bud? No, right? Thus, converting buds into flowers is an irreversible change. But the expansion and contraction of the iron ring is a reversible change.
