Did you know that learning about energy transfer technologies in science may help you learn about particular career choices?
Here's an example:
Fire Fighting
In order to protect themselves from the intense heat of a fire, fire fighters must wear protective clothing. This clothing uses special materials that prevent heat transfer.
When they are working, fire fighters use water to increase the transfer of heat. When they spray water over the flames of a fire, the liquid water quickly heats and changes to water vapour. This change in state transfers heat away from the fire.
If a
fire ladder is placed against the side of a building, a machine called
an inclined plane is made and allows fire fighters to enter the building to
continue to fight the fire.
Fire axes are another kind of machine: a
lever. When used to break through doors, they act as an extension of a
fire fighter’s arm.
In this theme, you will learn about all of these things. You will learn what heat is, how heat transfers from one object to another,
and how to increase or reduce heat transfer. To end this theme, you
will also learn how simple machines transfer energy.
As
you work through the theme, you might also consider other occupations
that use energy transfer technologies widely, such as mechanics, cooks,
machine operators, even deep sea divers!
