- %CO:A,12,72%Attainment target 11: Electricity and magnetism
-
- Pupils should develop their knowledge and understanding of electric and
- electromagnetic effects in simple circuits, electric devices and
- domestic appliances.
-
- Level 1 * know that many household appliances use electricity but that
- misuse could be dangerous.
-
- Level 2 * know that magnets attract certain materials but not others
- and can repel each other.
-
- * understand the danger associated with the use of electricity,
- and know appropriate safety measures.
-
- Level 3 * know that some materials conduct electricity well while
- others do not.
-
- * understand that a complete circuit is needed for an
- electrical device such as a bulb or buzzer, to work.
-
- Level 4 * be able to construct simple electrical circuits.
-
- Level 5 * be able to describe and record diagrammatically simple
- electrical circuits that they have made.
-
- Level 6 * understand the term voltage and be able to measure the
- potential difference across a conductor, such as a bulb,
- buzzer or heating element.
-
- * understand how electrostatic charge generated in everyday
- contexts can be safely discharged.
-
- * be able to recognise and explain simple electromagnetic
- effects in a range of common devices.
-
- * be able to measure and cost domestic electrical energy
- consumption by obtaining electricity meter readings.
-
- Level 7 * understand the magnetic effect of an electric current and
- electromagnetic induction.
-
- * understand the chemical effects of an electric current.
-
- * be able to interpret common electrostatic phenomena in terms
- of unbalanced charges.
-
- Level 8 * be able to conduct simple investigations with ammeters,
- voltmeters and joulemeters to measure quantities such as
- electrical resistance and energy dissipated in a device.
-
- * be able to explain how electricity is distributed on a
- national scale.
-
- * understand the behaviour of a circuit and its components in
- terms of a model of charge flow.
-
- Level 9 * be able to express the relationships between the following
- quantites in the appropriate units: charge, current,
- vootage, resistance and electrical power.
-
- * be able to calculate these electrical quantities by
- measurement and substitution of quantities in appropriate
- formulae.
-
- * be able to make informed judgements about the economic and
- environmental benefits and drawbacks associated with the
- different methods of generating electricity.
-
- Level 10 * know about thermionic emission and the production of X-rays.
-
- * be able to explain the use of X-rays, recognising that
- applications require compromise between priorities.
