What are conductors and insulators?

Warm Up 3. Study the picture above. When the sun comes out, the snowman melts, or changes from ____. solid to liquid liquid to solid gas to liquid solid to gas 4. Buoyancy is__________ The ability for an object to float To form a solution with another material The amount of matter something contains. evaporation 1. In the diagram above, the water in the pan is changing from a liquid to a gas, or ____. a. Melting c. condensing b. freezing d. evaporating 2. What is matter? The amount of matter something contains. Everything in the universe that has mass and takes up space The amount of salt in water The amount of space that matter takes up.

What is a conductor? A conductor is something which allows electricity to flow through. When dealing with thermal energy, conductors allow for heat to transfer easily from one object to the next An example of a conductor is: Scissors Paper clip Aluminum foil Iron Steel Copper Silver Mercury

What is a Insulator? An insulator is what makes electricity from not flowing When dealing with thermal energy, insulators do not allow for the transfer of heat from one object to the next. They help to keep in the thermal energy. Examples of insulators are: Cotton Paper Plastic Glass Rubber Air

Conclusions… Conductors allows energy flow through them. Conductors are materials that can carry energy - they conduct energy. Metal materials such as copper, iron, steel and aluminum are all good conductors of energy. Insulators do not allow energy to flow through them. Materials such as wood, plastic, rubber and glass do not carry energy and are called insulators – they don’t conduct energy.
