Slide 4
What is Electricity? Electricity is the flow of electrical
power or charge. It is a secondary source of energy which means we
get it from a primary source of energy such as coal, natural gas,
oil, nuclear power and other sources of energy. Types of
electricity? Static and Current electricity
Slide 5
Electricity has been moving in the world forever. Lightning is
a form of electricity. It is electrons moving from one cloud to
another or jumping from a cloud to the ground. Have you ever felt a
shock when you touched an object after walking across a carpet? A
stream of electrons jumped to you from that object. This is called
static electricity. Have you ever made your hair stand straight up
by rubbing a balloon on it? If so, you rubbed some electrons off
the balloon. The electrons moved into your hair from the balloon.
They tried to get far away from each other by moving to the ends of
your hair. They pushed against each other and made your hair
movethey repelled each other. Just as opposite charges attract each
other, like charges repel each other
Slide 6
Electric Energy (Electricity) energy made up of moving
electrons. Anything that uses a battery or gets plugged in uses
electric energy! Electron tiny particle of matter that has a
negative charge.
Slide 7
Predict what kind of setup will light a bulb. Demonstrate how
to construct a simple circuit.

Slide 10
An insulator is a material that resist the flow of electric
current. A conductor is a material that allows the flow of electric
current. How can sort conductors and insulators by creating a
chart.

Slide 12
What is a an electrical circuit? What is a parallel circuit?
What is a series circuit? Identify features of parallel and series
circuit using a KWL chart. How we compare series and parallel
circuit using a Venn diagram.
Slide 13
An electrical circuit is a network that has a closed loop,
giving a return path for the current. A network is a connection of
two or more components, and may not necessarily be a circuit.
Slide 14
A series circuit is a circuit where there is only one path from
the source through all of the loads and back to the source. This
means that all of the current in the circuit must flow through all
of the loads.
Slide 15
A parallel circuit has more than one path for electricity to
follow. Some parallel circuits has millions of paths to follow like
a computer.
Slide 16
Slide 17
Try to distinguish what material pertains to the topic. Narrow
down the information, you do not need to read everything on the
page. You will practice how to skim through websites looking for
what is important data. We are detecting if websites are rich in
data.
Slide 18

Slide 19
What can we do to conserve energy? List of safety rules
Slide 20
Why is it important to conserve energy? It is important to
conserve energy because it reduces pollution. Natural resources are
limited. We need to try to keep our planet clean for generations
after us. Save animals from extinction. It helps save money.
Slide 21
Replace bright bulbs with energy saving bulbs. Use a timer or
motion sensor to turn lights on and off. Turn off anything not in
use. Unplug unused appliances. Try using more battery power. Use
less electrical energy whenever possible. V IDEOS
