AQA GCSE Physics Required Practical 3: Resistance of a Wire

Resource to support the delivery of Required Practical 3 Investigating the Resistance of a Wire. The focus of the activity includes:

AT 1 – use appropriate apparatus to measure and record length accurately.
AT 6 – use appropriate apparatus to measure current, potential difference and resistance.

Skills developed on the specification include:

WS 2.2 – plan experiments or devise procedures to make observations, produce or characterise a substance, test hypotheses, check data or explore phenomena.
WS 2.3 – apply a knowledge of a range of techniques, instruments, apparatus, and materials to select those appropriate to the experiment.
WS 2.4 – carry out experiments appropriately having due regard for the correct manipulation of apparatus, the accuracy of measurements and health and safety considerations.
WS 2.6 – make and record observations and measurements using a range of apparatus and methods.
WS 3.1 – present observations and other data using appropriate methods.
WS 3.6 – present reasoned explanations including relating data to hypotheses.
WS 3.7 – be objective, evaluate data in terms of accuracy, precision, repeatability and reproducibility and identify potential sources of random and systematic error.
