Sample Learning Goals


For Teachers

Circuitry At Home JavaScript Simulation Applet HTML5


Instructions on how to use the JavaScript Simulation Applet


(Switch for Diagram View)


(Switch for World View)
Step 1: Choose a switch, let's say Switch A
Step 2: Click on Switch A, notice how the lights and switches in both view turn off at once
White Buttons represents the switch is opened,
while green (diagram)/ grey (world) represents a closed switch.
Note that the switches in both world and diagram views are interchangeable.

Power Button

(Power Button for Diagram View) [Power On]


(Power Button for World View) [Power On]
(Power Source for Diagram View - Yellow) [Power On]
Step 1: Click on either of the power buttons. Notice that both the buttons turns white.
(Power Button for Diagram View) [Power Off]


(Power Button for World View) [Power Off]
Step 2: Look at the Power Source in the Circuit View. It has now turned white.
(Power Source for Diagram View - White) [Power Off]
Step 3: Look at either views. Notice how the bulbs doesn't light up even with the switches closed.
(Diagram View)


(World View)
To enable the circuit to be powered again:
Simply click on the Power Button

'Wires' Check Box

(Wire? Check Box - Toggles the visibility of the wires in World View)
Step 1: Look at the World View
