LESSON ON CONDUCTION FOR LOWER SECONDARY STUDENTS

Topic: Transfer of thermal energy (Conduction)

Class: Lower Secondary students (Form II)

Time: 50 minutes

Aim: To introduce the concept of transfer of thermal energy (conduction)

Prior Knowledge:

Students should be familiar with the concepts of temperature and energy (heat energy).

They should also know how to read a thermometer.

Learning Outcomes:

After this lesson, the students must be able to:

1. define conduction

2. appreciate that conduction occurs mostly in solids

3. give examples of conductors

4. differentiate between good conductors and bad conductors

5. give uses of good conductors and bad conductors

Teaching Strategies used: Questioning, Brainstorming, Guided discovery, Group work, expository, demonstration.

Teaching Aids: Beakers, Water, Bunsen burners, Tripods, Wire Gauze, Thermometer, Metal Rods made of different materials, Wax, Thumb tacks, Stand, Clamp, Blackboard, Chalks.

Methodology: Starts on next page

Follow up:

1. Worksheets containing small exercises on conduction will be given to students.

The small exercises will consist of multiple choice questions, short structured questions and also fill in the blank type questions.

2. The use of audio-visual equipments where the students will be able to see some demonstrations of conduction.

3. Use of the internet and animations to show to students some simulations on temperature change, transfer of energy.

4. Ask students if they have encountered real life situations about conduction. A good example will be the cooking of food at home. Students will be asked to describe what are the processes involved and the related concepts.

5. Students will also be asked to do a small project on what they have learnt about conduction and also to do some additional research.
