Vocabulary:

An electric current (flowing electrons) produces a magnetic field (area of magnetic force with aligned spinning electrons.) (i.e. wrapped wire connected to a battery can pick attract some metals.)

An electromagnet is a magnet can be turned on and off using electricity. (motors, loudspeakers, microphones, & switches)

Matter of the day:

Light Bulbs

Diagram:

What is it?:

In 1879, Thomas Edison’s design team developed a carbon-filament light bulb in a vacuum to prevent burn-out. Different inert gases like argon, nitrogen, krypton, neon, xenon, and halogen.

Why does it matter?.

The major form of lighting for over 100 years.

Vocabulary:

Electric force is the attraction or repulsion between electric charges.

Chemical Energy is the energy stored in substances.

Batteries change chemical energy into electrical energy.

terminal: the points on a battery where electricity flows.

Circuit:a a path that allows electrons to flow.

Current:the flow of electrons.

Volt: the potential for the flow of electrons from a source.

Conductor:a material that allows electrons to flow.

Insulator:a material that prevents electron from flowing.

Resistor:a material that slows that flow of electrons.

    Matter of the day:

    Resistors

    Diagram:

    What is it?:

    A device made to slow the flow of electrons in a circuit.Often made of graphite (pencil lead), and thin metal wires or films. Lite bulbs, speakers, and other devices that use electricity can be treated like resistors.

    Why does it matter?.

    Used in electronics to control voltage and current.

    Matter of the day:

    Van de Graaff Generator

    Diagram:

    What is it?:

    A belt generates a negative charge by friction that builds up and stays on the dome. (static electricity)

    Why does it matter?.

    It can simulate lightning.

    _____________________________________________________________

    Vocabulary:

    Static Electricity: charges build up on an object, but they do not flow continuously.

    Electric Current: electrons flowing

    Electric force is the attraction or repulsion between electric charges

    Electric Field is a region around a charged object where the object’s electric force is exerted on other charged objects

    Conservation of charge: an object becomes charged only when electrons are transferred from one location to another. Charges are neither created nor destroyed. If one object gives up electrons, another object gains those electrons.

    There are 3 methods by which charges can be transferred to build up static electricity:

    • Charging by friction is the transfer of electrons from one uncharged object to another by rubbing.
    • Charging by conduction is the transfer of electrons from a charged object to another object by direct contact.
    • Charging by induction is the movement of electrons to one part of an object that is caused by the electric field of a second object.

    Static discharge the loss of static electricity as electric charges transfer from one object to another.
