What is a build up of static electricity caused by?
Friction
1 of 7
What happens when two materials are rubbed against each other?
Electrons are scraped off one material and dumped onto the other, electrons are negatively charged so this leaves a positive static charge on one and a negative static charge on the other
2 of 7
What happens to the electrons when polythene is rubbed with a duster
Electrons move from the duster to the rod
3 of 7
What happens to the electrons when the acetate rod is rubbed with a duster
Electrons move from the rod to the duster

How is static electricity responsible for attracting dust?
Dust particles are really tiny and lightweight and so are easily attracted to anything thats charged, many things around the house are made of insulating materials that get easily charged and attract the dust particles.

How is static electricity responsible for clinging clothes and crackles?
When synthetic clothes are dragged over each other, electrons get scraped off, leaving static charges on both parts, leading to attraction and therefore creating little sparks as the charges rearrange themselves.

How is static electricity responsible for bad hair days?
Static builds up on your hair giving each strand the same charge so they repel each other
