2. Everything is made of atoms!
Everything around us is made of
atoms.
But, what are atoms made of?
In the middle of each atom is a
nucleus.
The nucleus contains two kinds
of tiny particles, called protons
and neutrons. Moving around
around the nucleus are even
smaller particles called
electrons.
3. Electricity is caused by electrons
Electrons have a negative charge; While
neutrons, have a positive.
Positive and negative charges attract each other.
While, the same charges will always repeal each other.
4. Electricity is a basic part of our life and it is one of our
most widely used forms of energy.
We get electricity, which is a secondary energy source,
from the conversion of other sources of energy, like
coal, natural gas, oil, nuclear power and other natural
sources, which are called primary sources.
5. When electricity gathers in one place it is
known as static electricity
Static electricity is the imbalance of
positive and negative charges
-You come inside from the cold, pull off your hat
and......static hair!!
The static electricity makes your hair stand straight
out from your head.
6. When you take off your hat, it rubs against your hair.
Electrons move from your hair to the hat. A static
charge builds up and now each of the hairs has the
same positive charge.
The hairs try to get as far from each other as
possible. The farthest they can get is by standing up
and away from the others. And that is how static
electricity causes a bad hair day!
7. Electricity that moves from one
place to another is called current
electricity.
Electrical current is a measure of the amount of
electrical charge transferred per unit time. It represents
the flow of electrons through a conductive material.
A lightning bolt is one example of an electric current.
8. What's a circuit?
A circuit is a closed loop that electrons can travel in.
A source of electricity, such as a battery, provides
electrical energy in the circuit. Unless the circuit is
complete, that is, making a full circle back to the
electrical source, no electrons will move.
9. How to make a single circuit
1. Get a volt bulb, volt battery and 2 wires.
2. Screw a bulb into a bulb holder.
3. Remove about an inch of wire covering
from each end of the wires with a wire
stripper or a pair of scissors.
4. Connect one end of a wire to the positive
end of a volt battery and the other end to
the center of the bulb holder.
5. Connect the other wire to the negative
end of a volt battery and the other end to
the side of the bulb holder.
-Now your bulb will light up!!!
