Introduction:
I was looking
at electric heater and wondering how it gets hot? To use
the electric heater we usually plug it to the
electricity and turn a knob. It gradually starts to get
hot.
Electricity and heat
are two different types of energy. Does an electric
heater convert electrical energy to heat energy? How
does it do that? If electricity produces heat, why are
all the electric wires not hot? and how does the air
conditioning unit creates cold air?

Project
description:
In this project you will investigate to find out if electricity
can create heat. You will perform experiments to show the
heat producing property of electricity. Identify and get a good
understanding of devices that use electricity to produce heat
(Hair Dryer, Iron, Electrical Heater, ...)
As a part of your project, make a device to show that heat
producing properties of electricity can have many industrial
applications. Making a foam cutting tool can be a fun and useful
experiment. Following are two samples of Polystyrene foam cut by
foam cutting tools.
