Static electricity and sparks
静电与电火花
Description
Explain static electricity as the build-up of electric charge through friction, describe how charged objects attract or repel each other, and relate static discharge to everyday phenomena such as lightning
Mastery Evidence
- Explains that rubbing transfers electrons from one material to another, creating opposite charges
- States that like charges repel and unlike charges attract
- Links the concept of static discharge to the formation of lightning as a large-scale electric spark
Assessment Prompt
Can your child explain why a balloon rubbed on hair sticks to the wall, and connect this to the science of how lightning forms during a thunderstorm?
