Explaining
Conduction
Heat energy
What happens to
the particles as
the heat is
applied?
Vibrate
Faster
Collide
Transfer
How is the
energy passed
to the other
end of the rod?
STRETCH! explain how conduction occurs
As the particles gain heat
________, they _______
faster and c_______ with
the particles ________
surrounding them. This
_______ the heat energy.
Energy
Vibrate
Faster
collide
Closely
Transfers
The heat energy is
transferred down
the metal bar

Say what each part is made from, whether it is a conductor or
insulator and why that is important
