PHYSICS HTS LESSON PLAN
ICSE Class 7 Lesson Plan, Chapter – Heat
Chapter: Heat.
Date:7/10/25 to 24/10/25
Class:7B
No. of Periods: 4
Topic: -Heat
Subtopics
- Definition of Heat
- SI Unit – joule
- Effects of Heat:
- Change in Temperature
- Change in Size (Expansion)
- Change in State (Melting, Boiling)
- Chemical Change (Burning)
- Concept of Temperature
- Difference between Heat and Temperature
- Conversion between Celsius, Fahrenheit, and Kelvin Scales
Learning Outcomes
- Define heat and state its SI unit – joule.
- Explain the different effects of heat with everyday examples.
- Differentiate between heat and temperature.
- Relate the rise and fall of temperature to the flow of heat energy.
- Perform simple conversions between Celsius, Fahrenheit, and Kelvin scales.
Procedure
Introductory Activity:
Introducing the Topic by asking students when you place one hand in a bowl of warm water and the other in a bowl of cold water for a few seconds . Then, how each hand feels. This will lead to a short discussion on how heat is a form of energy that makes a body feel hot or cold**, and how it flows from a hotter body to a colder one. This experience connect to the concept of Heat and Temperature as a measure of the degree of hotness.

- Explain the definition of heat and its SI unit (joule).
- Discuss effects of heat using simple examples:
- When sunlight falls on metal furniture, it becomes hot (change in temperature).
- Telephone wires sag in summer (expansion – change in size).
- Ice melts to water (change in state).
- Burning of paper (chemical change).
- Introduce the concept of temperature and its measurement using a thermometer.
- Explain the difference between heat and temperature with real-life analogies.
- Write of conversion formulae between Celsius, Fahrenheit, and Kelvin . Giving excercise on conversion.
- Summarize the entire concept through a Rainbow Mindmap connecting effects, units, and relationships as students draw this in their notebook.
Activities
- Observation Touching warm and cold water to feel the difference.
- Observation of metal expansion in daily life (railway tracks, lids of jars).
- Drawing and colouring a rainbow mindmap on Heat.
- Interactive blog puzzles and flash cards, Converter
Values/Skills
- Observation and comparison skills.
- Scientific curiosity and reasoning.
- Respect for safety and accuracy in experiments.
- Collaborative and communicative learning.
Assessment
- Oral Q&A and class discussion.
- Worksheet on effects of heat and temperature conversions.
- Rainbow Mindmap review of key concepts.
- Interactive puzzles, flash cards, and blog-based quiz through Speed Up Science.
