As part of their science work, Year 4 have been investigating conductors and making electrical circuits:

Lewis and Joe have made a switch from a piece of wood and drawing pins to make the light go on and off.
Amy, Tommy and Chloe have made a circuit that would light up a bulb behind the clown's nose, by using two wires, a battery, a bulb and a bulb holder.
Natalie and Thomas made a circuit that would make the clown's bow tie rotate. We connected one end of a wire to the positive end of a battery and the other end of the wire to a motor. Then we took another wire and connected it to the negative end of the battery and to the other side of the motor. We put two bow ties onto the motor and it whizzed around.
Oscar and Amber made a circuit that would make the clown's bow tie rotate. All the colours merged to make a greenish colour as it whirred around.
Rebecca and Oscar investigated whether a pencil was a conductor and would make a good part of a circuit. We made a dimmer switch by adding a pencil (cut in half to show the lead inside) to our circuit. When the two wires were close together on the pencil lead the bulb was bright as we moved the wires apart the light went dimmer.
Nicole and Joseph made the bulb go dimmer by using a pencil as a dimmer switch.
Ria and Lisa Marie made a circuit with a paper switch. They made the switch by putting two butterfly clips on a piece of card and connecting them with a paper clip.
We made a bulb very bright by connecting it to four batteries which gave it more power but when we added a motor to the circuit the bulb went dimmer. We think this was because the motor was using a lot of the power from the batteries. Scott and Chiara.
We made our bulb go brighter by adding an extra battery to our circuit. Caitlin and Sam.
Sarah-Beth, Rebecca and Brandon used very short wires to connect a battery to a bulb and found that the bulb was very bright because the power had less distance to travel.
We made the bulb go very bright when we connected it to four batteries instead of one. It was so bright that we thought the bulb might burst with so much power. Connor and Thomas.
