At the end of this unit
in terms of scientific enquiry
most pupils will: select and use appropriate equipment to investigate circuits which include cells, bulbs and switches; measure current; identify patterns in their results and draw conclusions about series and parallel circuits; describe hazards associated with electricity and how to deal with them
some pupils will not have made so much progress and will: explore circuits using appropriate equipment; identify patterns in their results and use these to describe the behaviour of simple circuits; identify and report on hazards associated with electricity
some pupils will have progressed further and will: plan and carry out a systematic investigation of series and parallel circuits to obtain sufficient evidence to draw conclusions; give examples of the development of scientific ideas about electricity,
eg Galvani and Volta
on
electric current, and explain how electricity can be hazardous to humans
in terms of physical processes
most pupils will: construct a range of working electrical circuits and represent these in circuit diagrams; state that electric current is the same at all points in a series circuit and divides along the branches of a parallel circuit; use a flow model to describe resistance and to distinguish between electric current and energy transfer in a circuit; compare and contrast the advantages of series and parallel circuits in use,
eg fuses, ring main
some pupils will not have made so much progress and will: construct simple electrical circuits and represent these diagrammatically; give examples of useful circuits; state safety rules for use of electricity
some pupils will have progressed further and will: relate voltage of cells and batteries qualitatively to energy transfer in circuits; use a flow model to explain the difference between electric current and energy transfer; apply the idea that nerves are electrical conductors to explain electrical hazards
