GLOSSARY
Atom: something so small that you
need a microscope to see it and is
everything ariund us.
Electrons: part of an atom which spins
around the protons and neutrons
Protons: the positive side of an atom
which is in the middle with neutrons
Neutrons: the negative part in the
middle of an atom
Power plant: a place outside of the city
with lots of generators
Generater: a device which we use to
transport
Circuit: A connection between a
energy source and power source
Parrellel circuit: when two pathways
connect to the same power source
Series circuit: when there is one
pathway with many energy sources but
one power source
Current electricty: a flow of atoms in
a circuit

Electricity
What is Electricity?
BE AMAZED BY HOW IT
WORKS
My opinion is, electricity is a source of
energy that we use in everyday life such
as turning on light bulb. If you want
something that you need to plug in or
has an on and off switch to work it
needs electricity. It makes light, sound,
heat and or motion. Electricity is made
up of atoms. An atom is made up of
electrons and protons and neutrons.
The electrons move around the protons
and neutrons, which are in the middle.
There is a certain amount of protons and
neutrons in each atom. Say there were
six, half the light switch on to light a of
that would be positive and the other half
negative. Therefore, for electricity to
work you need a circuit and a power
source for the electricity to connect to
a power source that is usually a power
plant or many generators that connect
to different places. A circuit is needed
for electricity to move. A circuit is a
connection between, say, a light bulb
and a battery that is the light bulb’s
power source. You use wires to
connect the light bulb to the battery
that makes the light bulb work.
However, there is a trick to it. There
is a negative (-) and positive (+) to the
battery if you have not noticed. There
is also one on the light bulb.

HOW DOES ELECTRICTY
WORK?
For electricity to work you need a
circuit as I said before in ‘What is
Electricity?’ what is a circuit? A
circuit iqs a connection between a
power source and, say, a light bulb.
There are two different types of
circuits. One of them is a parallel
circuit. A parallel circuit is when you
have two pathways that connect to
the same power source. A pathway is
like a circuit but may not connect to
the power source right away. Another
type of circuit is a series circuit. It
sounds like it is supposed to have
many pathways but it only has one
but still with a couple light bulbs.
Here is a picture of a parallel and
series circuit:
HOW DOES ELECTRICITY
CONTECT TO MAGNETISM?
WHAT DIFFERENT FORMS
OF ELECTRICTY ARE THERE?
There are many different forms of
electricity. Such as static
electricity or current electricity.
CURRENT ELECTRICTY:
Current electricity is when there is a
flow of atoms in a circuit. There are
types of current electricity. DC or direct
current and AC alternating current. DC
is when you get power from batteries,
solar panels and generators. It only goes
in one direction. However, an AC
current is when you get power from the
walls of your house. Like an outlet. For
an AC current the flow of electrons
switches every mill-second.
Did you know? That for an AC current
a light flickers every time the flow of
electrons switches. You can only see it
in slow motion.

STATIC ELECTRICITY:
Static electricity is when electrons
transfer from one atom to another. You
need an electrical charge for it to work.
Like rubbing a balloon on your head.
The electrons transfer from your hair to
your balloon. Now the balloon has a
negative charge from the electrons and
your hair has a positive charge from the
other electrons left on your hair. The
negative electrons attract the positive
electrons so your hair stands up when
the balloon is a tiny bit away.
EXPERIMENT :
Blow up a balloon and tie it. Then rub it
against your hair. See, afterwards, in the
mirror if your hair follows the balloon. If
it does then you have just made an
electrical charge! Good job!
In my opinion, electricity connects to
magnetism by the positive and negative
from a battery and a north and south from
a magnet. In a circuit positive and
negative are on a battery while north and
south are on a magnet. They connected
because if you where to put two north
sides from two magnets they repel. Also
when you put two wires in the positive
side of a battery and attach the other ends
of the wires to a light, will the light
work? No, it won’t because they are like
magnets. They don’t repel but they can’t
make the light work like you can’t get
two north sides of two magnets to stick to
each other. I found out that many
conductors to complete a circuit are
attracted to magnets. So they turn out to
be either north or south. Whichever way
they get attracted to they turn the
opposite such as a rock got attracted to
the south side of a magnet then the rock
would be north.
EXPERIMENT:
Get two donut magnets and a compass
in good shape. Hang one magnet on
string and tape the string on the edge of
a surface that doesn’t have anything
magnetic around it then try to find
which side is north and which side is
south. To help you, use the compass..
WHAT WOULD DAILY LIFE
BE LIKE WITHOUT
ELECTRICTY AND
MAGNETISM?
Without electricity in certain weather
would sometimes mean not many will
survive. That is, in my opinion. On
the CBC website we were asked to
look at some of the videos from the ice
storm of 1961 in Montréal. After we
had to record what life would be like
without electricity and what uses of
electricity you needed to survive.
During an ice storm many trees fall on
power lines which means that certain
houses nearby may not get electricity.
It also takes a lot of time and people to
get the electricity restored in only a
couple days. It is much harder to
restore it because many of the tools
that are needed use electricity such as
light for the workers to see.
Meanwhile, people must get to better
shelters that aren’t their homes. To get
to shelters they need they need
vehicles but their own vehicles are
under a lot of snow. So they use
emergency vehicles that are somewhat
bigger.
