DESCRIPTION
Atoms have protons, neutrons, and electrons. Same number of protons and electrons, it is balanced and neutral Sometimes electrons get knocked out of place – free electrons If they go to where other electrons are missing, this creates a current of electricity!

Electricity!
By Denzel and Jessica
Electricity
• Atoms have protons, neutrons, and electrons.
• Same number of protons and electrons, it is balanced and neutral
• Sometimes electrons get knocked out of place – free electrons
• If they go to where other electrons are missing, this creates a current of electricity!
Static Electricity!
• Charge that stays on an object
• When something gives up or gains electrons
• Does not move along a wire or other conductor
Current Electricity!
• Electric charges are called electric current.
• Free electrons continuously move to spaces where electrons are missing.
Examples
• Light bulbs• Cars• Computers
Conductors
• A conductor is a material that current can pass through easily
Examples
• Metal• Paper clips• Silverware• Wires• Water
Open-Closed Circuits
• If a switch is opened electrons stay still. No electricity moves.
• If a switch is closed electrons move and energy is released.
Parallel-Series Circuits
• The series move in a circle
• The parallel circuit moves in a straight line
• The parallel series moves in a straight line and in a circle
Chemical
• Chemical changes cause energy
• Batteries• Glow sticks• Pop Rocks
Mechanical
• Generator• Robots• Trains• Windmill• Motorcycles
Nonconductors
• Do not allow electricity to pass through easily
• Insulators • Rubber• Plastic• Glass
Household Electricity
• What are some types of household electricity?
• Cords • Computers• TV• Microwave• Stove
Safe Use Of Electricity
• Don’t pull cords• Don’t put metal in an
electrical appliance
