1. Electricity Basics of electricity

2. Electricity Atoms – The smallest unit of each element Electrons – negatively charged particles in atoms Ions – charged atoms or molecules Magnets – A metal with opposite charges on each side. Magnets can be used to create electricity.

3. Static Electricity Lightning Charge Build up Energy Release Path of Least Resistance

4. Current, Resistance, & Voltage Electricity flowing through a substance is called an electric current.  Current is measured in amperes. The opposition to the flow of electrons through a material is called resistance.  Resistance is measured in ohms. The amount of force per electron flowing through a substance is called voltage.  Voltage is measure in volts.

5. Conductors and Insulators As with heat, electricity flows better through some materials than others. Materials with low resistance to the flow of electrons are called conductors. Materials with high resistance to the flow of electrons are called insulators.
