NCERT Class 6 Science Curiosity: Chapter 8 — A Journey through States of Water
This chapter, "A Journey through States of Water," from NCERT Class 6 Science Curiosity, explores the different states of water. It begins with a conversation between Aavi and Thirav about ice and water, leading to the understanding that they are different forms, or states, of the same substance. The chapter introduces Activity 8.1 to observe the conversion of ice to water, highlighting that water flows while ice does not. It then delves into the phenomenon of water disappearing from puddles and utensils, prompting discussions on absorption by soil and evaporation. Activity 8.2 is suggested to investigate how water disappears from surfaces. This chapter helps students understand the basic concepts of states of matter and physical changes related to water, crucial for their CBSE science curriculum.
