4 On to building one and two loop circuits.
Locate your book and kit.
When you are ready, go to the next slide.
5 Find these items in your kit: battery
band
1.5 Volt
battery
light
bulb
buzzer alligator
leads
6 new word alert - SERIES This is called
a SERIES circuit.
Connect the bulb and the motor
in ONE big loop.
1 The bulb and motor are connected
one after the other in a single loop.
Electricity flows through each part in turn.
If one part in the loop goes out, so will all the others.
7 new word alert - PARALLEL Connect the bulb
and motor in a
TWO loop circuit.
Is the light brighter in
the one or two loop circuit?
2 IF the bulb goes out, the motor will still run
in this two loop or parallel circuit.
The parts in
the two loop circuit are connected in PARALLEL.
