How Electricity Works. Electricity is a flow of electrons. A circuit will not work if there is a break in it. The electrons can not flow. An electric current flows between two points because there is a difference in

voltage. (“energy level”) The positive terminal of a battery is at a High Voltage level. The negative terminal is at a

Low Voltage level.

An Electric current behaves like the ball on the piece of wood shown below.

The current will flow from high to low just like the ball.

What happens if both children raise their ends?

Technical Vocabulary

• Electrons

• Circuit

• Output

• Voltage (energy level)

• On / High / +

• Off / Low / -

• Time

Using Electricity worksheets.

You will have completed the Using Electricity worksheets with the Electronics Kits.

Now have a look at Using Electricity 5. Make sure you have the “Working

away from the computer sheet.”

Setting up Control Console

You will need a clear desk near to a plug socket.

Plug in the power lead to the Console. Plug into the wall power socket. The Console will make a noise when it is

turned on.(Do not turn it on until you have connected your outputs.)

When you have finished do not take the lead from the console just turn off the wall socket.

Connecting your circuit• Connect one red plug with crocodile clip on, to

OUTPUT 1. Use a screwdriver to tighten.

• The second to the green socket next to it.

• Avoid unplugging these once they are connected as they will break if not carefully removed.

SAFTEY FIRSTSAFTEY FIRST

DO NOTDO NOT connect an external power supply (mains or battery) to any of the Console terminals.

DO NOTDO NOT connect a Red Output directly to a green Ground Terminal.

DO NOTDO NOT connect a Red Output directly to another Red Output.

DO NOTDO NOT be responsible for breaking the equipment.

Replacing the battery.

Remove the battery and connect the crocodile clips to the metal studs.

Turning the bulb on. Instead of typing the instructions

into a computer, we are keying them into the Control Console.

Start with the OUTPUT you want to control.Then select either:-

HIGH/+ (ON) LOW/- (OFF)

Then you need to say how long for.

Time Then a length of time. 1= 1 tenth of a second. 10 = 1 second.

e.g. 1 10OUTPUT H/+

Next you can add another circuit.

Remember to key in the correct OUTPUT!

Key in instructions to first turn on your light bulb, then your fan.

We are going to make an Advertising Board using an Electric Circuit. We are going to include three factors.

Light.ColourMovement.

Planning and making your board.

Come for a Spin!

Light up your Night!

•Either lay a piece of paper over your circuit and mark where you need your holes

•Or use the planning sheet.

Here is one I made earlier!
