Opposite poles
attract.
Like poles repel.
Force is dependent on
distance
What are the
characteristics of
magnets?
Magnetism?
Attraction of a
magnet for another
object.
What does
magnetism have to
do with electricity?
What is it creates
a magnetic field?
When magnets are
further apart, what
happens to the
magnetic field?
It grows
weaker.
When magnets get
closer together, what
happens to the
magnetic field?
It grows
stronger.

What are
conductors?
Glass
Porcelain
Plastic
Rubber
What are
insulators?
Why are
humans a good
conductor of
electricity?
Electricity will always take the
shortest path to the ground. Your
body is 60% water and that makes
you a good conductor of electricity.
If a power line has fallen on a tree
and you touch the tree you become
the path or conductor to the ground
and could get electrocuted.
Why do we use
insulators on
wires?
The rubber or plastic on an
electrical cord provides an
insulator for the wires. By
covering the wires, the
electricity cannot go through
the rubber and is forced to
follow the path on the
aluminum or copper wires.
Energy comes
from:
What is a power
source?
In a circuit, why
are the wires
made of copper?
Copper is a conductor
Explain which circuit will have brighter
light and why:
Circuit 1 will have
brighter light because it
has to transfer energy into
2 light bulbs and circuit 2
has to light 3 bulbs.
Explain the difference between a series
circuit and a parallel circuit.
In a series circuit, the
energy only has one way
to travel.
In a parallel circuit, the
energy can go more than
one way.
Explain
what
happens if
one of the
bulbs
burn out.
The other bulb will be
brighter because it will get all
of the electricity.
Energy is transferred
from a power source
and then it can power
a light bulb, a sound,
and produce heat?
Why does
a circuit
work?
Margaret
Mead
anthropologist, writer,
scientist;
environmentalist,
women's rights
advocate, studied
tribes in India
Nikola
Tesla
The "Tesla coil," Tesla also invented
fluorescent lights and a new type of
steam turbine, and he became
increasingly intrigued with the wireless
transmission of power.
Michael
Faraday
British physicist and chemist, best
known for his discoveries of
electromagnetic induction and of
the laws of electrolysis. His
biggest breakthrough in electricity
was his invention of the electric
motor

Describe the graph below:
Temperature changes
from day to night
It is a line graph and
shows change over
time.
Using this table
can you tell
what happens to
the
electromagnet
when you add
more loops?
It gets stronger.
