In class we have been talking about electricity, how it is made, what it is used for, what life was like in the olden days when there was no electricity and how we can save energy.
Next we had a chance to make electrical circuits. First of all we made circuits using 2 wires, a battery and a bulb. It took good group work to get the bulb lighting. We know that circuits are like circles made of wires, battery and bulb. The circuit can't be broken in any place if you want the bulb to light. 
When we were all able to do this, one of the wires was taken away and we made the circuits again with just one wire, a bulb and a battery.
Using our circuits we could make a lighthouse. You need a kitchen roll cardboard, 2 wires, a battery (and holder) and a bulb (and holder). We can even make the lighthouse bulb flash on and off by connecting and disconnecting the bulb.
