Lesson One

• Electricity Basics
• What is electricity?
• Who are the inventors of electricity?
• How do we get electricity?
• What everyday objects do we use that need
  electricity?

5
Vocabulary
Electricity-the flow of electrical power or
charge. Blackout- what happens when the
electrical supply is interrupted. Electric
circuit- unbroken path along which an electric
current exists or is intended or able to flow

Inventors and Inventions

• Benjamin Franklin invented the lightning rod in
  1752.
• Faraday invented the generator in 1831.
• Alexander Graham Bell invented the telephone in
  1876.
• Thomas Edison invented the light bulb in 1879.
• Latimer worked with Edison and invented the
  carbon filament in 1880.
• Woods invented the telephone transmitter in 1885.

Lesson Two

• Insulators and Conductors
• What are insulators?
• What are conductors?
• In what ways can we classify insulators and
  conductors?
• How can we sort insulators and conductors by
  creating a collage?

9
Conductors

• Some materials will allow electricity to travel
  through them. We call these materials conductors.
  
• The piece of metal in this circuit allows
  electricity to travel through it, so the bulb
  lights up.

10
Insulators

• Other materials do not allow electricity to pass
  through them. We call these materials insulators.
  
• There are lots of different insulators, such as
  plastic, rubber or glass. The plastic does not
  allow electricity through, so the bulb does not
  light up.

Lesson Three

• Investigating Properties of Metals and Magnets
• Magnets attract or repel certain objects /
  metals.
• Magnetic fields extend beyond the actual magnet.
• Investigating Properties of Metals and
  Electricity
• All metals conduct electricity.
• Not all conductors are magnetic.
• Electricity and Magnetism
• Electrons moving around atoms create magnetic
  fields.
• Electrons moving through conductors create
  electricity.
• Moving a conductor through a magnetic field can
• generate electricity.

13
Vocabulary

• Force a push or pull.
• Attract magnets pulling together.
• Repel magnets pushing apart.
• Magnet an object that attracts iron.
• Permanent Magnet magnet made from a material
  (such as iron) that stays magnetized.
• Temporary Magnet a piece of iron that behaves
  like a magnet when it is touching a permanent
  magnet.
• Induced Magnetism the influence of a permanent
  magnet's magnetic field on a piece of iron which
  makes the iron behave like a magnet.

PET Manipulative Test Does the object conduct
electricity? Does the object attract a
magnet?
15
Lesson Four

• Series and Parallel Circuits
• What is a series circuit?
• What is a parallel circuit?
• What are electrical circuits?
• How do we change circuits?

16
Electrical Circuits
An electrical circuit is a device that gives
energy to the charged particles that make up the
current, devices that use current, and the wires
that connect them, such as lamps, electric motors
and electronic computers. .

17
What is a series circuit?

• There is only one path for electrons to flow.
• All components are connected end-to-end, forming
  a single path for electrons to flow.

18
What is a parallel circuit?

• All components are connected across each other,
  forming exactly two sets of electrically common
  points.
• All components are connected between the same set
  of points.

19
Changing Circuits

• You can change circuits by adding more bulbs.
• If you add more bulbs to a circuit, the bulbs
  will glow less brightly, because the bulbs have
  to share the electricity that the cell provides.
• Adding more cells to a circuit will make the
  bulbs glow brighter because there is more
  electric power.
• You can also change a circuit by changing the
  length of the wire.
• As the wires get longer the bulbs
• get dimmer.

20
Lesson Five

• Electricity Safety Tips
• What are the safety tips when working with
  electricity?
• Can a song help us to remember the safety tips
  when working with electricity?
• How can we add the safety tips we learned onto a
  
• Filamentality webpage?

21
Electricity Safety Tips

• Never play with electrical cords, wires,
• switches, or plugs.
• Never use a hairdryer near a sink or bathtub.
• Never play an electrical radio or television
• near a bathtub or sink.
• Before you climb a tree, look up. If a power
• line is nearby or touching, stay away from the
• tree.
• Never touch anything that runs on
• electricity when your hands are wet.

Kids

• Replace incandescent bulbs with CFL to save 50
  of lighting Energy.
• Use a timer or motion sensor to turn lights on
  and off.
• Turn off anything not in use.
• Try using more battery power.
• Use less electrical energy whenever possible.

We hope you learned a lot about electrical
energy and had loads of fun throughout all the
interesting activities we had, such as creating a
PowerPoint presentation, a Filamentality web
page, a Webquest activity, a song, spreadsheets,
tables, graphic organizers, a collage, a
scavenger hunt and lastly a class play. What a
unit!
