Making circuits

We have begun our Science work on circuits.  Here we are making simple circuits on Tuesday.

Today we have investigated adding a switch.

Then we added an extra bulb.

We discovered that adding an extra component like a bulb or switch to the circuit makes the light from the bulb dimmer (less bright) than when only one bulb is used in the same circuit.  We decided this is because the current (energy) has a longer journey around the circuit and so the 'power' is less.

We are looking forward to the next step of our circuit investigations!
