Use your knowledge from the past couple weeks to discuss everything you know about these two situations. What observations can you make about each scenario? 

Why does the dog get shocked by the fence but the birds don’t get shocked by the wire?

Specifically, current is the speed that the charge is moving (The unit of current is the Ampere = Coulomb/second).

Current is caused by an electron being pushed onto an atom, which causes an electron to jump over to the next atom,….  

Select “Intro” (or “Lab.”  It doesn’t really matter). 

Drag parts from the left onto the page.  You will need: (1) a battery; (2) a switch); (3) a dog); and (4) wire.  Note: you can change the orientation and size of the parts using the circles.

Connect the parts into a circuit to model the dog in the video.  

The battery can represent the electric fence 

click on the battery and change voltage to 120V

The switch can represent the dog peeing.  

The wires can represent the path for electrons to flow.  

Click on the switch to close the circuit (The closing of the switch represents the dog starting to pee on the electric fence)

Add a screenshot of your circuit to your notebook.

Closed Circuit: A complete electrical circuit that allows current to flow.  (When you turn a light switch on, you close a circuit).

Open Circuit: An incomplete electrical circuit that prevents current from flowing.

 of a man that touched a low hanging powerline. In many cases, touching a low hanging power line means being electrocuted. On the other hand here is a 

 that crashes into the wires but he doesn’t get shocked.
