Introduction:

The Electricity and Magnetism unit covers Static Electricity, Current Electricity, Magnetism, and Electromagnetism.  The unit is structured around the lab work and in-class activities.  Many of the activities are inquiry based.  They attempt to allow students to discover the laws of science involved in the unit. Everything has been provided as a Word 1997-2004 .doc document and as a PDF.  This redundancy is in case the formatting fails to download properly.

Prerequisites:

The Electricity and Magnetism unit should be proceeded by:

• Basic atomic structure unit
• Introduction to the periodic table unit
• Bonding unit:  including valence electron
• Work, energy, power, and simple machines unit

Scope:

1.  Topics to be taught:

Static Electricity and Charge:

• Atoms and charge
• Electric Forces
• Polarization of charge
• Charging techniques: Conduction, Friction, Induction
• Electric discharge
• Difference in charge causes charge to flow
• All charge wants to go to the ground

Current Electricity:

• Potential Difference / Voltage
• Producing Electric Current
• Alternating and Direct Current
• Resistance
• Batteries and Cells
• Electric Power
• Series and Parallel Circuits
• Ohm's Law

Magnetism:

• Magnetic properties: Poles, Domains, Field Lines
• Magnetic Fields
• Interactions between magnets
• Types of Magnets
• Earth as a Magnet

Electromagnetism:

• Magnetic force and electric current
• Applications of Electromagnetism: Motors, Speakers, etc...

2.  Skills to be taught:

• Communication: oral and written
• Computation
• Critical thinking
• Experimentation: conducting, data analysis, design
• Observation
• Creating Tables
• Unit conversions
• Notetaking

Sequence:

The entire unit should take about three weeks to complete for a class that meets 200 minutes a week.  The timing of the unit revolves around the lab work and in-class activities.  The lab/activities are arranged in numerical order.  The #5 activity, Jurassic Park, and the #4 activity, Potential Difference and Circuits can be interchanged.  The review games prepare students for the group quiz and unit exam.  The games work best the day before each assessment.
