S/N | Time | Teaching/Learning Activity | Resources | Rationale/Remarks |
---|---|---|---|---|
1. | 5 min | Introduction: | PowerPoint slides | To elicit students’ prior knowledge and situate them within the topic. |
Brief students on lesson outline | ||||
Explain that thermal energy is a form of energy that can be transferred. Recall methods of heat transfer from lower sec science. | ||||
2. | 15 min | Lesson Development | ||
Conduction | ||||
Teacher explains the mechanism of conduction using the prepared slides covering conduction in solids, liquids and gases. This is followed by an explanation of how the presence of free electrons in metals speed up the rate of conduction | PowerPoint slides | A deliberate teacher directed approach adopted. | ||
3. | 10 min | Handout 1 – Conduction | Handout 1 | This is to allow students some time to consolidate the information provided by the teacher. |
Students are given some time to complete the handout on the main points involved with conduction | ||||
5. | 15 min | Convection | PowerPoint slides | A deliberate teacher directed approach adopted. |
Teacher explains the mechanism of convection using the prepared slides. Teacher then goes through examples to show how convection occurs in various applications. | ||||
6. | 10 min | Handout 2 – Convection | Handout 2 | This is to allow students some time to consolidate the information provided by the teacher. |
Students are given some time to complete the handout on the main points involved with convection. | ||||
7. | 15 min | Radiation | ||
Teacher explains the mechanism of radiation using the prepared slides. Teacher then goes through characteristics of good absorbers/radiators. | PowerPoint slides | A deliberate teacher directed approach adopted. | ||
8. | 10 min | Handout 3 – Radiation | Handout 3 | This is to allow students some time to consolidate the information provided by the teacher. |
Students are given some time to complete the handout on the main points involved with radiation. | ||||
9. | 5 min | Applications | ||
Teacher goes through some applications that make use of thermal energy transfer eg. Thermos flask, food packaging etc. | PowerPoint slides | To help students understand how thermal energy transfer may be applied to real-life situations. | ||
10. | 5 min | Conclusion | ||
Recap of main ideas and key learning points by teacher. | PowerPoint slides | To recap the lesson and highlight the key concepts learnt. |
