KS3 - Circuits 2 (animated)

KS3 - Circuits 2

Has basic animated slides with examples of electron movement and principles of carrying charge.
Follows from KS3 - Circuits 1 and leads on to concept of resistance.
Ends with question about lightning (air has a high resistance, how does lightning 'flow'?)

Infomation:

Links to prior topics :
Basic physics, Circuits 1

Skills Developed:
Diagrams/graphical work, physical to abstract, logic

Learning Objectives :
Revise PD, electrons and charge

To identify new circuit components and understand conductors
To explain what is happening in a circuit, using different models
To infer a relationship between voltage current and resistance

Assessment Criteria for Objectives:
Comparison of models
Understanding of relationships between VIR

Teaching & Learning Strategies :
Visual and tactile,
labelling,
abstraction,
comparison modelling,
modelling with rope as circuit


Resources / Materials Required

School circuit kit (cells, cables, switches, bulbs)
Ammeters
Optional Rope Model

Lab Safety Considerations [CLEAPSS / Hazcards / COSHH]

Electrical safety (1.5-3v, IE negligible, but good time to start on electrical safety)


Practical Work/Demonstration
Circuit creation – Battery + bulb + ammeter to measure,
Optional rope model of a circuit

Literacy /Numeracy/ICT incl. School-wide objectives

Numeracy links with voltage calculations ,
literacy with the labels.
