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
- Comprehension: listening and reading
- 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.
