This is an online activity that provides you with various exercises on rounding whole numbers.

In this lesson you will learn that:

• Static electricity is a build-up of charge in an object.
• The build-up pf charge is caused by insulating materials rub against each other.
• The motion of these charges causes small shocks, lightening and sparks.
• These charges can be detected. 
• Certain materials can be classified as insulators, and others as conductors.
• Capacitors are small devices in circuits which can store charge.
• Lightning rods are used to allow charges from strikes to travel safely and dissipate in the Earth
