Hi, I am Jared, and welcome to Fun Science
Demonstrations for Young Learners.
A little message, Morse code, are you getting
it?
Our big idea today is that electricity
needs a path to follow and sometimes
that path is
easy to follow, and sometimes it is
not so easy.
Some things conduct electricity and some
things
do not conduct electricity. And what is
neat today is we get to experiment
and find out what things are good
conductors and what things are not such good
conductors.
How do I do that, how do I show you electricity?  I could bite down on this and
get shocked and aaahhhhh!
The easiest way is the light bulb. Watch our pathway.
We have electricity flowing through the
pathway lighting up the light bulb.
Sometimes it is easy. Sometimes things
really
allow the electricity to flow through. We
call them conductors.
Take a look at this wire. We have a little
metal end
and it is covered with plastic. If I
connect metal to metal,
Whoa! electricity flows, it must be a good
conductor.
Watch what happens when I touch the
metal to the plastic-
no light bulb! The electricity
is not flowing through that plastic.
It is an insulator,
it does not really conduct it well. So I
have all these cool things here
to really test and see, do they conduct
electricity or do they not?
Let us start with my favorite, the
hammer.
We have the metal part-let us try it-let us
create our pathway.
Ah, look at that,
it is flowing through our pathway. 
It conducts!
What about the wooden part? Wood, wood,
electricity is not flowing. That must be
an insulator.
Wood, it must be an insulator. The
screwdriver, another tool of my
liking. Wait, the metal on the hammer
worked, I wonder if the metal on the
screwdriver is going to work. So we
touch and touch. Hey, it is flowing-
must be a conductor. What about the
plastic?
The wood did not work, let us try the plastic.
Let us form our pathway...it is not flowing...
we call it an insulator. Another tool,
a c-clamp. Metal,
it is working: conductor. What about a wooden
popsicle stick?
It is not conducting:
insulator. A glass marble, all right,
touch-ooh, it is rolling-touch,
it is not working. Must be an insulator.
A clothespin-
we have wood, we have metal. Hmm, I am
thinking the wood
does not conduct, it is an insulator. What
about the metal band?
Touch, touch, we have light! Electricity,
science is so cool. Hey, if you want to
