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?
Learning LogWhat type of circuit are Christmas lights? How do you know?
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.
TIC TAC TOE
0 Do not write on any papers except for the Metric Conversions
0 Complete at least three activities over the next day and a half
0 Have fun!
Learning LogCompare and contrast current electricity and static electricity.
