Theme of the lesson

Ampere force and Lorentz force

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

10.4.1.2 – to apply the left-hand rule and describe the effect of a magnetic field on moving charged particles and electrical conductor;

Lesson Objectives

Learners can predict the direction of the force on a charge moving in a magnetic field

Evalution Criteria

Students have achieved the objective if they are able to apply the left-hand rule and describe the effect of a magnetic field on moving charged particles and electrical conductor;

Language Objectives

Learners can:

use Fleming’s Left Hand Rule to explain to other learners in the class the direction of the magnetic force on a current-carrying conductor (speaking and listening skills)

Subject-specific vocabulary & terminology:

Fleming’s Left-Hand Rule

magnetic field direction

current-carrying conductor

conventional current

Useful sets of phrases for dialogue and writing:

The thumb represents...

The first finger represents...

The second finger represents…

The magnetic force is perpendicular to...

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.

•      keep doing?

•      start doing:

-Students to summarize main ideas, evaluate class processes, answer questions posed at the beginning of the lesson, and link both to the past and the future

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 research the use of strong magnetic fields in mass spectrometers and in isotope separation (e.g. for radiological dating or for enrichment of uranium).

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
