What’s it about?

In this science experiment we will be learning more about electrical current, and how electrical circuits are useful to us in our lives everyday. Many very complex electrical circuits exist today, from radios, cell-phones, GPS systems and many others. These are all based on very simple electrical circuits, like the one in the experiment below, connected together to form such an appliance:

Topics covered

Electrical current, LED, In series

What will I need?

  • 9-VOLT BATTERY
  • COPPER WIRE
  • COLOURED LED’S
  • SHEET OF CARDBOARD
  • STICKY TAPE
  • MAGIC MARKERS

Procedure (Method)

Unfortunately, this section is only available in the e-book version of the project.

How does it work?

Unfortunately, this section is only available in the e-book version of the project.

The power or ‘electrical energy’ stored in a battery can only be released and allowed to flow when a complete circuit is made out of wires that conduct electricity. In the above experiment a complete circuit is made from the negative (-) terminal of the battery to the positive (+) terminal of the battery, through the LED’s placed inside the circuit, as the negatively charged electrons wish to travel to the positive portion of the battery.
