Secure: I can describe how materials can become charged. Develop: I can describe the effect of static electricity and explain how charges can repel and attract. Exceed: I can explain static electricity in terms of electron transfer. https://www.youtube.com/watch?v=yc2-363MIQs Starter: What is a static shock? What causes them?

Static electricity: build up of charge from electrons that have been moved to or from an insulator. Insulating material: a material that does not allow electrons to move through it easily. Electrostatic charge: charge caused by the movement of electrons to or from an insulator. Bronze Silver Gold Copy down the definition for static electricity. Copy out all definitions.

Give students 5 minutes to come up with the ideas that rubbing causes objects to become charges, once charged, they will attract or repel electrons and so cause the phenomena depicted.

Electrostatic charges When you rub certain types of insulating materials together they become charge either positively or negatively. Charge caused by electrons being moved from one material to the other.

Opposite charges attract Like for like charges repel. When two electrically charged bodies are brought together they exert a force on each other. Opposite charges attract Like for like charges repel.

The boy has gained a negative electrostatic charge while sliding down the polythene slide. His hair all has the same type of charge so all the individual strands are repelling each other.
