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

How Electricity Impacts Today's Life

• We use electricity for light, heat, transportation, everything!
