Theme of the Lesson

Electromagnetic Devices

(generator, electromagnetic relay, and transformer)

Learning objectives that are achieved at this lesson (Subject Programme reference)

Learners can infer from appropriate experiments on electromagnetic induction that a changing magnetic flux can induce an e.m.f in a circuit

Lesson objectives

10.4.2.3 – to explain the operating principle of electromagnetic devices (electromagnetic relay, generator and transformer)

Evaluation criteria

Students will have achieved the objective if they are able to

explain the operating principle of electromagnetic devices (electromagnetic relay, generator and transformer)

Language Objectives

Learners can use a simple demonstration to explain the factors affecting the size and direction of the induced e.m.f in a coil

Subject-specific vocabulary & terminology:

-electromagnetic induction

-induced e.m.f

-magnetic flux

Useful sets of phrases for dialogue and writing:

-There is an induced e.m.f in the coil because...

-The size of the induced e.m.f increases because...

-The direction of the induced e.m.f will reverse if…

Values instilled at the Lesson

Respect for other’s opinions. Group work. Problem-solving skills. Communication skills. Working with potentially harmful apparatus will help students develop a responsible attitude. And working in pairs and/groups encourages friendliness. Communication skills are encouraged by working with a partner and answering questions.

Cross-curricular Links

Lifelong learning of the topics today by applying their knowledge this day for their SET, SAT, final external summative examination and other examinations they will take in the future.

ICT Skills

Calculations using engineering calculators Ask the students to do further reading on the topic from the internet, especially from the Institute of Physics and PhET Colorado websites.

Previous Learning

·         magnetic fields; representation of fields by field lines fields of permanent magnets and relationship between magnetic field and current in conductors;

·         electrical equations: V = IR, P = IV;

·          magnetic fields; flux density and the tesla.

Differentiation – how do you plan to give more support? How do you plan to challenge the more able learners?

Assessment – how are you planning to check students’ learning?

Health and safety regulations

Weak Learners:

Review the previous lesson.

Revise the topic on key terms used in magnetism benefit of the weak learners.

Strong Learners:

-To derive the following formula:

E=Bυlsinα

Checking Students’ Learning:

-Using observation and the Question-Answer strategies at the start, during, and at the end of the lesson.

-Using the computer generated and/or tutor-feedback

-Using self, peer, and group feedback, online quizzes, and formative assessments.

-Checking the quality of their work and understanding from their notebooks, whiteboard work, answers on the active board, group presentations and discussions, developed posters, and responses on the worksheets.

Follow all standard laboratory procedures, rules, and regulations in the Schools’ Laboratory Safety Guide and to remain safety conscious always
