Basic principles of electricity

• Ohms Law

• Electromagnetic Induction

• Alternating Current

Model thinking

• A model is an approximation that allows us to understand and make

  predictions about a system

• All are models are wrong, some are useful

• How do you separate the important factors in a model from the less

  significant?

• How do you determine which models to use?

• Ohm's Law is a model

Research skills

• How do you discover more about a topic?

• How do you synthesize this information to answer a question?

• How do you find the right question to ask?
