NCERT Class 7 Science Curiosity: Chapter 7 — Heat Transfer in Nature
This chapter, "Heat Transfer in Nature," from NCERT's Class 7 Science Curiosity textbook, explores why some places are hotter or colder than others, introducing the concept of heat transfer. It begins with a relatable scenario of siblings discussing climate differences between Gangtok and Kerala, highlighting the role of proximity to the equator and coastlines. The chapter then delves into the practical application of heat transfer through cooking utensils, explaining why metals are used due to their conductivity. An activity demonstrates conduction using a metal strip and pins, prompting students to observe and predict how heat travels and causes the pins to fall, thus introducing the fundamental principles of heat transfer in a scientific context.

Practice questions
- Why are cooking utensils usually made of metals? Answer: Cooking utensils are made of metals because metals are good conductors of heat, allowing food to be heated efficiently.
- What is the main source of heat and light for the Earth? Answer: The Sun is the main source of heat and light for the Earth.
- Name two factors that influence the climate of a place. Answer: Proximity to the equator and having a long coastline are two factors influencing climate.
