Much different than it is for most of us.

Does somebody want to try and define the word electricity?

These are the questions and definitions we need to know to generate a definition for electricity? –What is electric charge? –What is electrical energy? –What are electrons –What is electric current? –What is an imbalance of charge? –What is an electric field? –What is voltage? –What is electric power? –What is a spark? –What is electromagnetism? –What is electrical science? –What is electrodynamics? –What is electrostatics? –What are electrical phenomena?

Electricity is related to charges, and both electrons (-) and protons (+) carry a charge. Electricity is related to charges, and both electrons (-) and protons (+) carry a charge. Copyright © 2010 Ryan P. Murphy

Annoying Tape. –Teacher gives each student 2 long pieces (10 centimeters each) strips of clear tape. Make non-stick handles by folding a small amount tape on itself. –Stick one piece of tape to table. –Stick the other piece of tape on that tape. –Quickly pull tape from table and then apart. –Observe what happens to the tape when it gets close to each other and then eventually your arm. Try and dispose of in trash barrel by shaking the tape from your hand and not picking. Copyright © 2010 Ryan P. Murphy

What happened!

–When you removed the tape from the table you gave it an electrical charge. When you peeled the tape apart from each other, one piece of tape gained more of a charge than the other.

We usually only notice static electricity in the winter when the air is very dry.

We usually only notice static electricity in the winter when the air is very dry. During the summer, the air is more humid.

–The water in the air helps electrons move off you more quickly, so you can’t build up a large static charge.

What happened? Balloon gained electrons from rubbing (

What happened? Balloon gained electrons from rubbing (now more negative). The match is neutral and is attracted to the negative balloon. –Balancing on coin reduces friction.

Demonstration 2: Packing peanuts. –Put some packing peanuts in a plastic cup and tape it to the top of the generator. –Turn on the generator and away they go! Copyright © 2010 Ryan P. Murphy If you have a “demo” wasp nest, the wasp paper in pieces works very well.

Demonstration 3 – Bad Hair day. –One student to stand on plastic trash barrel. –Put both hands on generator. –Turn it on and hair should stand up on end.

Other Demonstrations: –Blow bubbles near the generator. –Place aluminum pie plate on generator in stack. –Light a candle near generator to observe electrical winds. –Tape many long strips of tissue paper to generator. –Tie an aluminum can so it hangs just above the generator.

Coulombs Law: Any two charged objects will create a force on each other. Opposite charges will produce an attractive force while similar charges will produce a repulsive force.

–Coulombs Law: The greater the charges, the greater the force. The greater the distance between them, the smaller the force.

If your car gets struck by lightning in a thunderstorm, will you be safe. Why?

If your car gets struck by lightning in a thunderstorm, will you be safe. Why? Yes

Answer: You will be safe because your cars metal chassis acts like a Faraday Cage.

Answer: You will be safe because your cars metal chassis acts like a Faraday Cage. The charged particles travel around the outside of the car and into the ground.

A Faraday cage is a metallic enclosure that prevents the entry or escape of an electromagnetic field.

–For best performance, the cage should be directly connected to an earth ground.

Rockin Quiz! –This is your chance to rock it out in science class so don’t just sit there. At least rock your head or tap your desk etc. –After some intro slides, teacher will call on a student to rock it out on their way to the board. –Student goes to board and touches the picture that represents AC or DC on the AC/DC logo (If using a screen just point and drum the air). –Student will then pick a new student to go to the board as the teacher changes the slide. –Thunderstruck video (For the music during quiz and I didn’t see anything inappropriate ). –http://www.youtube.com/watch?v=v2AC41dglnMhttp://www.youtube.com/watch?v=v2AC41dglnM

“DC”

“Its one way!”

“AC”

“It Alternates!”

Is this (AC) Alternating Current, or (DC) Direct Current?
