NCERT Class 6 Science Curiosity (Sanskrit): Chapter 7 — तापमानं तत्परं च
This NCERT Class 6 Science Curiosity Chapter 7, ऊष्मपादानं च (Heat and Cold), introduces students to the concepts of heat and cold. It explains that our bodies can sense whether something is hotter or colder than ourselves, using the example of a child feeling feverish. The chapter emphasizes that we cannot always rely on touch to determine temperature accurately. It includes an activity (Kriyākalāpa 7.1) where students use three containers with hot water, tap water, and ice-cold water. By placing one hand in hot water and the other in cold water, and then both hands in tap water, students observe and predict differing sensations, highlighting the limitations of touch for temperature measurement. This chapter helps students understand basic thermal properties and the importance of careful observation in science.
