It is intended for all science teachers but particularly those who are not physics specialists. It is, primarily, aimed at 14 to 16 year old pupils but can also be used at a higher level as a precursor to a more in-depth study of this topic. Normally, the activities would fill a 45 to 60 minute lesson but could be spread over two lessons if needs be.

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

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:

What Is The Relationship Between Current, Voltage And Resistance?
Learning Outcomes
Knowledge

• to identify the components needed to investigate Ohm’s Law and to draw the circuit diagram
• to describe the effect that voltage has on current
• to describe the effect that heat has on resistance of conductors and semi-conductors
  Analysis
• to use Ohm’s Law to calculate voltage, current and resistance

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