What’s it about?
When electrical components are connected ‘in series’, it means that they are connected one after another in a chain. A light bulb can be illuminated when a battery is connected in a simple circuit, but only when the circuit is ‘complete’, meaning the flow of electricity forms a continuous ‘loop’. In this science experiment, use a ‘series’ electrical circuit to make an education board for testing your friend’s worldly knowledge:

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 or other ‘conductors’ that conduct electricity. In the above experiment, when your friends touches the probes to the correct bolts, which is connected to each other at the back of the board, a complete circuit is made from the positive (+) terminal of the battery to the negative (-) terminal of the battery. The current flows from the battery through the wires, connecting two bolts and ‘light bulb’ and back to the battery. When the circuit is complete and the current is flowing, the light bulb shines to indicate a correct answer.
