Video and lesson investigations on the topic of static electricity. Key concepts include:
- A rubbed comb (or balloon) can pull some other objects towards it. It does not need to touch the object to make it move.
- A rubbed balloon can also make things move apart.
- When a balloon is rubbed, it becomes ‘charged’.
- This charge is called ‘static electricity’.
- Static electricity can make objects attract or repel each other.
- A static charge results when one object picks up electrons (negative charges) from another object.
- The object that picks up the electrons becomes negatively charged.
- The object that loses electrons becomes positively charged.
- These oppositely charged objects will then be attracted to one another.
- Opposites attract!
