This week we have a bigger challenge. We have to design and build a parallel circuit with two batteries, one motor, one lightbulb and three switches. This week we are making and investigating simple electrical circuits. The materials that we need are: - a lightbulb -a battery to give the power -some wires to connect all the elements - a switch , to close the circuit. He have also learnt that electricity flows from the negative pole to the positive pole, so it's really important to set the connections well. |
