Circuit Breakers

An animation illustrating the role of an electromagnet in circuit breakers used to prevent mains circuits from over-heating.

I have many others of the same format; these can be seen by visiting my shop on the TES website (search: rtyler62).

If you buy this resource, please print the Readme document as it contains the instructions and details of the files included.

NOTE: MACROS MUST BE ENABLED FOR ALL POWERPOINT PRESENTATIONS

Support Material

Users and timings
It is intended for all science teachers but particularly those who are not physics specialists and is, primarily, aimed at 14 to 16 year old pupils. Normally, this resource would fill a 45 to 60 minute lesson but could easily be extended to two lessons.

Learning outcomes
The learning outcomes are based on Bloom’s taxonomy of hierarchical classification: knowledge, comprehension, application, analysis, synthesis and evaluation. The lesson title and learning outcomes are:

How do circuit breakers prevent fires?

Learning outcomes

Knowledge

To describe the main components of a circuit breaker.

Comprehension

To explain the role of an electromagnet in a circuit breaker.

Differentiation:
The activities have varying degrees of differentiation; please refer to the Readme document.
