Electricity is Electronics Technology Education The future is looking bright!
Electricity is Science Electricity is chemistry Atoms contain protons and electrons Electrons flowing from one place to another is known as electricity.
The atom Atoms: contain electrons which are negatively charged contain protons which are positively charged want to have an even number of protons to electrons
Attraction Likes and Dislikes Two positives repel+/+ R Two negatives repel-/- R A positive and a negative attract+/- A Magnets: north & north repel n/n R south & south repel s/s R north & south attract n/s A
Cats chase birds electrons chase protons Electrons (-), Protons (+) Electrons are attracted to the positive protons Electrons want to pair with the protons until there is an equal number of protons to electrons.
Static electricity The carpet experiment –Rub your feet into the carpet (like a cho cho train). –Then…using your finger…touch a “friend” What happens…???
The Shocking Truth When you drag your feet across the carpet… THINGS are jumping onto you. Electrons jump onto your body and create an imbalance of electrons to protons You are now negatively charged.
Your Unsuspecting Friend Your friend is positively charged (extra protons) When you sneak over and touch your “friend”, your extra electrons jump over to your “friend” This movement causes a The electrons then partner with your friend’s extra protons…creating a balance.
To Make a Complete Circuit Summit OBJECTIVE: You must return to where you STARTED… Puff puff
To Make a Complete Circuit An electrical circuit is complete when the electricity from the…. Power Source: Passes through…. Conductors: or Loads: And returns back to the power source through the… Battery Clip:
Dead Battery ?
Closed Circuit vs. Open Circuit
Series Circuit “closed circuit”
Series Circuit Open Circuit
Parallel Circuit Closed circuit
Parallel Circuit Open Circuit
When you get to the Safety Rules site …move through the slides using the “next” and “previous” buttons. Take notes of the Safety rules.Safety rules Neatness + completeness count…the notes will be submitted for marks. Click the link. then click then then Safety Rules
Click the link below and follow the instructions in Electrical Safety Grades K-6
