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!
