How to Make
an Electrical Circuit Lab
to see the movie of this lab!)
We wanted to find out if we
could make an electrical circuit and learn a little more about electricity.
1 battery and battery holder
1 bulb and bulb socket
3 pieces of #22 coated hook-up wire, each 20 cm. long
1 piece of #22 coated hook-up, 80cm.long
1 magnetic compass
1. Use 2 of the 20 cm. wires
and connect them
to the battery holder and the bulb holder so the
bulb can light up.
2. Unconnect one of the wires that connects to the light bulb and battery
and add the other 20 cm. wire and add the switch to the battery holder
so it has one wire to the battery holder which connects to the light bulb,
and one wire that connects to the light bulb and switch and to the other
side of the battery.
3. Now we saw electricity was flowing we took the light bulb and the 20
cm. wire that is connected to the battery holder and replace it with the
80 cm. wire and connect that to the battery holder and the switch and
it should look like the 80 cm. to the battery to the switch and the 20cm.
wire to the switch and the other side of the battery holder.
1. While we were doing this
experiment we were able to see if we made a circuit the bulb would light
2. When we took out the light bulb and replaced it with the 80 cm. wire
and turned the switch on after a while it got hotter, the longer we left
it on the hotter it gets.
3. We also found out if we put even just one wire that was connected to
one of the holders which was put connected by the plastic part of the
wire it wouldn't work so we had to make sure the wires were connected
by the metal part of the wire.
In conclusion we learned how
electricity works. It needs a path of metal to go from one side of the
battery to the other. If there is a break in the path then electricity
will not travel. Plastic will not let electricity through. If a lot of
electricity can just run through the wires without a bulb, the wires get
