Lesson plan – Physics
Topic: Thermodynamics - Heat transfer.
Target group: 7 graders
Time: 45 minutes
Lesson objectives:
1. Students know the basic terms and meanings (e.g. heat, temperature, conduction,
convection, radiation).
2. Students explain how heat transfers.
3. Students describe how heat transfers occur by conduction, convection, and radiation.
4. Students give examples of heat transfers that occur in everyday situations.
Methods:
Individual work, pair work, experiments,
Materials:
Worksheets, quizlet exercises, kahoot quiz, items necessary for experiments:
1. Temperature test: non-contact thermometer, 1 book, 1 cola can
2. Ice melting: for each pair of students: 4 ice cubes, 1 black plastic lid, 1 black metal lid, 1
white plastic lid, 1 white metal lid
3. Heat sensation: 3 bowls of water: tap/regular water, hot water, cold water.
4. Popping balloons: 2 balloons, 2 candles, water
Procedures:
1. Introduction:
a. Introducing the topic.
b. Brain storming: What is temperature? What is heat?
c. Questions to answer after the lesson: Why do you feel colder when you get into
the sea? What makes something warmer or colder?

2. Development and practice:
a. Introducing basic terms – using PowerPoint presentation
b. Experiment no 1: temperature test
i. One students touches a book and a can and describes the temperature –
which is colder? What will happen to the temperature of these objects if
we leave them for the whole day on the beach?
ii. Measuring the temperature and explaining the idea of conduction using
the example of a freshly baked cake and a roaster (same temperature,
various time of conduction)
iii. Students fill in the text in a worksheet about the experiment – fill in the
gap task.
c. Experiment no 3: heat sensation
d. Experiment no 4: popping balloons
i. Teacher balloons over the candles – one balloon is filled with air, the
second one with water.
ii. Students observe the experiment and tries to explain why the balloon
with water does not pop.
iii. Teacher summarises the experiment and students fill in the worksheets.
e. Experiment no 5: melting ice cubes
i. Students do experiment in pairs and make notes on the observation
worksheet
ii. Teacher summarises experiment.
f. Experiment no 6: idea of radiation, convection and conduction
i. Teacher uses a candle and a metal stick to explain the terms.
3. Checking for understanding:
a. Quizlet exercise – matching term with its definition
b. Kahoot quiz – choosing the correct answer about heat transfer in everyday life.
c. Teacher asks students for everyday examples of heat transfer
4. Closure:
a. Teacher asks students to write on papers what they have learnt during the
lesson and then collects the papers for evaluation
b. Teacher summarises the lesson, revises the basic idea.
c. Teacher asks students for the answers posed at the beginning of the lesson.
