Static electricity
I can describe how objects with a positive or negative charge attract or repel other charged objects.
Static electricity
I can describe how objects with a positive or negative charge attract or repel other charged objects.
Lesson details
Key learning points
- Some objects can be charged by rubbing with certain materials.
- Objects with a static electric charge can exert a force on other objects (that contain electric charge).
- The electrostatic force acts at a distance.
- Objects with opposite electric charges attract each other.
- Objects with the same electric charge as each other repel each other.
Common misconception
Pupils often think ‘negative’ refers to a neutral material, that there is only one type of charge and that friction creates charge.
The understanding of the particle model of matter needs to be secure before introducing atomic structure. Using dynamic models to help pupils visualise what is happening to the negative charge helps them progress in their thinking.
Keywords
