Conductors and insulators micro-lesson

Do you struggle with balancing your kids’ screen time with their education? Say hello to 1Question, the app that solves this problem with a fun twist! Our app lets your child earn screen time minutes in their favourite apps by watching educational videos and correctly answering quiz questions. And the best part? You get to decide which apps to lock behind learning using 1Question. 

Learning time​

Kids learn by watching short, engaging video lessons.

Materials that let electricity pass through them easily are called electrical conductors. Materials such as iron, copper, and steel are good electrical conductors. This is why these materials are used inside cables and electrical devices. For example, the metal used in plugs allows electricity to transfer from the wall socket through the plug and into a device such as a TV. Materials that do not allow electricity to pass through them easily are known as electrical insulators. These include plastic, wood, and rubber. That is why these materials are used to cover materials that carry electricity. For example, the plastic covering that surrounds wires and cables is an electrical insulator and this stops you from getting electric shock when handling these objects.
