Thinking about actions to take: Power and Voltage
Teaching Guidance
for 11-14
There's a good chance you could improve your teaching if you were to:
Try these
- relating the brightness of lamps to what's happening to the current and voltage in each loop
- using semi-quantitative reasoning and physical models, such as the rope loop
Teacher Tip: Work through the Physics Narrative to find these lines of thinking worked out and then look in the Teaching Approaches for some examples of activities.
Avoid these
- diving straight into the sums to be done
- using ad-hoc rules to generate the sums to be done
Teacher Tip: These difficulties are distilled from: the research findings; the practice of well-connected teachers with expertise; issues intrinsic to representing the physics well.
