Day 1: Introduction to Heat
Topic: Heat and Temperature
विषय: ऊष्मा और तापमान
Learning Outcomes
- Define heat and temperature.
- Understand the difference between hot and cold.
Teaching-Learning Activities
Teacher asks:
- Why do we feel hot in summer?

- गर्मियों में हमें गर्मी क्यों लगती है?
- हम पंखे का उपयोग क्यों करते हैं?
Explain:
Heat:
- A form of energy that makes things hot.
ऊष्मा:
- ऊर्जा का एक रूप जो वस्तुओं को गर्म बनाती है।
Temperature:
- Degree of hotness or coldness.
तापमान:
- किसी वस्तु की गर्मी या ठंडक का माप।

Examples:
- Metal spoon becomes hot in tea.
- Iron pan becomes hot while cooking.
Activity Observe different objects (metal, plastic, wood) and identify conductors and insulators.
Assessment Choose the correct answer:
Wood is a: a) Conductor
b) Insulator
Homework List three objects made of conductors and insulators.
Day 4: Transfer of Heat – Convection and Radiation
Topic: Convection and Radiation
विषय: संवहन और विकिरण
Learning Outcomes
- Explain convection and radiation with examples.
Teaching-Learning Activities
Convection: Heat transfer through movement of liquids and gases.
संवहन: द्रव और गैसों की गति द्वारा ऊष्मा का संचरण।
Examples:
- Sea breeze
- Water boiling
Radiation: Heat transfer without a medium.
विकिरण: बिना माध्यम के ऊष्मा का संचरण।
Examples:
- Heat from the Sun
- Heat from fire
Activity Observe why we wear light-colored clothes in summer.
Assessment Ask:
- How does heat reach Earth from the Sun?
Homework Write one example each of conduction, convection and radiation.
