
Get out a blank sheet of paper and fold it
into 16 equal squares (4 x 4)
Write down one vocabulary word in each box
from the following list in a random order.
Be sure to save space to write definitions in
each box along with the word.



Protons and electrons
Come near eachother they create 2
different forces


Attraction
repulsion
charge
• Protons and electrons
• Come near eachother they
create 2 different forces
• Attraction
• repulsion
Electric field
• Extends outward from anything
with a charge
• When charged particle moves
into electric field, it is either
pushed or pulled
Atom review
• Why are you not attracted to
your pen or coat, etc
• Remember atom is neutral
because protons = electrons
So how produce charge
• Electrons are free to move
• Lose electron = + charge
• Gain electron = - charge
• Just as atom can become
charged, so can entire object
Bingo Clue:
A flow of electric charge (moving electricity)
Bingo Clue:
- Opposite charges attract
- Like charges repel
Bingo Clue:
Opposition to the flow of electric charge
Bingo Clue:
Material with atoms containing loosely
bound electrons which permits electrons to
flow freely
ex. copper (metal)
Bingo Clue:
Area around charged particles that
exerts a force (push or pull) on other
charged particles.
Bingo Clue:
When electrons always flow in the same
direction
EX. Battery
Bingo Clue:
Buildup of electric charges on an object.
(unbalanced charge)
Bingo Clue:
Electrical Potential: amount of stored electric
charge
Note: it requires work to move a charge.
Bingo Clue:
A complete closed pathway for
electricity to flow
Bingo Clue:
Current = voltage
resistance
I = V/R
Bingo Clue:
When electrons flow back and forth,
reversing their direction regularly
(+ to -) (- to +)
EX. Wall Socket/Plug
Bingo Clue:
1. Friction- rubbing two objects together
2. Conduction- direct contact of two objects
3. Induction- rearrangement of electric
charge without touching
Bingo Clue:
When all parts of a circuit are connected
one after another in the same path
Bingo Clue:
Physical Property of Matter that can give
rise to an electric force of attraction or
repulsion
• Protons (+)
• Electrons (-)
• Neutrons (no charge)
Bingo Clue:
Material with atoms containing tightly bound
electrons that do not permit electrons to
flow freely
ex. rubber
Bingo Clue:
IF YOU JUST SAID BINGO…
YOU OWE RYAN A POP!
Bingo Clue:
When the parts of a circuit are connected in
separate pathways or branches
Chemistry Review Notes

The following note pages are the
definitions from your bingo card that
need to be formally recorded in your
science journal.
The Basics




Charge: Physical Property of Matter that can give rise to an
electric force of attraction or repulsion
 Protons (+)
 Electrons (-)
 Neutrons (no charge)
Rule of Charged Particles: Opposite charges attract, Like
charges repel
Electric Field: Area around charged particles that exerts a
force (push or pull) on other charged particles.
Static Electricity: Buildup of electric charges on an object,
(unbalanced charge)
Methods of Providing Charge
1. Friction- rubbing two objects together
2. Conduction- direct contact of two objects
3. Induction- rearrangement of electric charge
without touching

Ohm’s Law

A relationship exists between current, voltage,
and resistance.


Current = Voltage
Resistance
I=V
R
AC vs. DC

Alternating Current (AC): When electrons flow
back and forth, reversing their direction
regularly (+ to -) (- to +)


EX. Wall Socket/Plug
Direct Current (DC): When electrons always
flow in the same direction

EX. Battery
Circuits: Series/Parallel

Circuit: A complete closed pathway for
electricity to flow
Series Circuit: When all parts of a circuit are
connected one after another in the same
path
Parallel Circuit: When the parts of a circuit
are connected in separate pathways or
branches
