**Flipping the Poles!**IWBAT understand why the magnetic poles are flipping through reading, taking a clicker quiz and completing an activity aaporal.**DO NOW**• Use bar magnets and iron filings in petri dishes to model magnetic fields • Draw a magnets magnetic field and flow in notebook**Reading Comprehension Clicker Quiz**• Read the article to answer the questions**The Wandering Pole**• Complete the activity in notebook • Answer the questions to VIII ON THE PAPER • Turn in your paper**Magnetic Domain**Electromagnetism Magnetic declination Magnetic field Magnetism Magnetic pole Magnetosphere Learning log Write a summary about magnetism that includes at least three vocab words.**It’s Electric**IWBAT collaborate to build and take notes to understand how magnetism and electricity relate aaporal.**DO NOW**• Watch video on FLIPPING POLES • Write TWO higher level questions about video that could be used as quiz questions**Flipping Poles**• Skip to page 27 • Complete graphing • Answer questions • Turn in with name to box**Electricity**• What is an electric current? • An electric current is the flow of electrons through a material • An 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**• What is an electric circuit? • An electric current will not flow automatically through every wire. • Current flows only through electric circuits • An electric circuit is a complete path through which electric charges can flow**Electricity**• Let’s model a circuit • What parts of a circuit does our model represent? • Your circle? • The ball? • Your teacher? • CLOSED VS OPEN CIRCUIT**Electricity**• Electrons in a circuit move from NEGATIVE to POSITIVE • Anode: NEGATIVE end of battery • Cathode: POSITIVE end of battery**Learning Log**Recreate the circuit from the video**It’s Electric Day 2**IWBAT write and discuss notes while building models to understand conductivity and types of circuits aaporal.**DO NOW**• Build a circuit • Test WOOD, A METAL WASHER, A PAPER CLIP, ALUMINUM, AND A PLASTIC FORK • Which materials conduct electricity or let electrons flow through them**Electric Circuits**• As you watch the video, define the following words and give examples: • Conductor • Insulator • Resistor • Series circuit • Parallel circuit**Electric Circuits**• Remember, electron currents cannot flow through just any material • Conductors: materials in which electrons move freely • Insulators: materials in which electrons cannot move freely Check out which materials are conductor and insulators**Electric Circuits**• In a conductor, some of the electrons are only loosely bound to their atoms • EX: metals, copper, silver, aluminum • In an insulator, the electrons are bound tightly to their atoms and do not flow easily • EX: plastic, rubber, glass, wood**Electric Circuits**• Resistors: as charges flow through a circuit the pass through resistors. • Resistors use electrical energy as they interfere with or resist the flow of charge**Parts of a circuit and their symbols**• Energy Source • Makes charges move around or flow in a circuit • Resistor • Resists the flow of the electric current • Think volume dial**Parts of a circuit and their symbols**• Switch • Controls the flow of electricity (on/off) • Load • anything 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 flow overall 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. Series Simple**What happens when one load is out in a simple or series**circuit?**Learning Log**What 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**• WATCH TOM AND JERRY WHILE YOU THINK ABOUT HOW ELECTRIC CURRENTS CREATE MAGNETS**ELECTROMAGNETS REVISITED**Electromagnets are made of coils of wire with electricity passing through them. 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**• Do not write on any papers except for the Metric Conversions • Complete at least three activities over the next day and a half • Have fun!**Learning Log**Compare and contrast current electricity and static electricity.
