Electricity

0What is an electric current?0An electric current is the flow of

electrons through a material0An ampere or amp (A): The

amount of charge that passes through the wire in a unit of time is the rate at which the electric current flows

Electricity

0What is an electric circuit?0An electric current will not flow

automatically through every wire.

0Current flows only through electric circuits

0An electric circuit is a complete path through which electric charges can flow

Electricity

0Let’s model a circuit0What parts of a circuit does

our model represent?0Your circle?0The ball?0Your teacher?

0CLOSED VS OPEN CIRCUIT

Electricity

0Electrons in a circuit move from NEGATIVE to POSITIVE

0Anode: NEGATIVE end of battery

0Cathode: POSITIVE end of battery

Build a Circuit

Learning LogRecreate the circuit from the video

It’s Electric Day 2IWBAT write and discuss notes while building models to understand conductivity and types of circuits aaporal.

DO NOW

1. Build a circuit 2. Test WOOD, A METAL WASHER, A

PAPER CLIP, ALUMINUM, AND A PLASTIC FORK

3. Which materials conduct electricity or let electrons flow through them

Electric Circuits

0As you watch the video, define the following words and give examples:1. Conductor2. Insulator3. Resistor4. Series circuit5. Parallel circuit

Electric Circuits

0Remember, electron currents cannot flow through just any material

0Conductors: materials in which electrons move freely

0Insulators: materials in which electrons cannot move freely

Check out which materials are conductor and insulators

Electric Circuits

0In a conductor, some of the electrons are only loosely bound to their atoms0EX: metals, copper, silver,

aluminum0In an insulator, the electrons are

bound tightly to their atoms and do not flow easily0EX: plastic, rubber, glass, wood

Electric Circuits

0Resistors: as charges flow through a circuit the pass through resistors.0 Resistors use electrical energy as they interfere

with or resist the flow of charge

Energy SourceMakes charges move around or flow in a circuit

Parts of a circuit and their symbols

ResistorResists the flow of the electric currentThink volume dial

Parts of a circuit and their symbols

SwitchControls the flow of electricity (on/off)

Loadanything that is using the energy that is being delivered by the electric current in a circuit

Parallel Circuit: creates several paths for the electron to take

If you add more paths more opportunities for electrons to flowoverall resistance decreases

Parallel Circuit: the electrons can still flow if one part of the circuit is

out

Simple and series circuits: A complete circuit with only one path for the

current to take.Simple Series

What happens when one load is out in a simple or

series circuit?

Electromagnetic Review

IWBAT review electricity and magnetism by collaborating to complete tic tac toe activities aaporal.

DO NOW

0 WATCH TOM AND JERRY WHILE YOU THINK ABOUT HOW ELECTRIC CURRENTS CREATE MAGNETS

ELECTROMAGNETS REVISITED

1. Electromagnets are made of coils of wire with electricity passing through them.

2. Moving charges create magnetic fields, so when the coils of wire in an electromagnet have an electric current passing through them, the coils behave like a magnet.
