The ability for an object to float b. To form a solution with another material c. The amount of matter something contains. d. evaporation

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 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.
