QUESTION
Does Electricity Move Better Through Thick Wires Or Thin wires?
MENU
HYPOTHESIS
We Think That Electricity Moves Better Through Thick Wires Because Electricity Needs
More Space To Move.
MENU
MATERIALS
• 3 Plastic Straws
• 3D Batteries
• Electrical Tape
• Steel Wool Pad
• 3 Small Light Bulbs (Like For a Flashlight)
• Camera To Take Pictures
MENU
PROCEDURES
1.First put your 3 batteries on a flat surface.
2. Cut the straws the exact same length as the batteries
3.Put one straw on the side of each battery and tape it onto the
battery using the electrical tape.
4.Take the steel wool and pull the strands apart. Make a small pile
on the table.
5.First, take 3 strands of the steel wool and roll them together until
they make a wire.
6.Then, take 6 strands of the steel wool and do the same thing.
7.Then, take 10 strands of the steel wool and roll them together
until they make a wire.
8.Now you have 3 wires. Put each wire into one of the straws that
are attached to the batteries.
9.For each wire, tape one end to the negative end of the battery (
the flat end that has a minus sign on it.)
10.Wrap the other end around the bottom of the flashlight bulbs.
11. Move the end of the light bulb down until it touches positive
side of the battery (the part that sticks out.)
12.If your circuit is complete, the bulb will come on. The picture
below will help you.
13.Do this for all 3 batteries. Write down on the other page how
bright each bulb is using the numbers 1-10 (10 begin very bright.)
14. Do this 2 times for each battery.

Write 1-10, and 10 being very bright and 1 being not bright at all.

RESULTS AND CONCLUSIONS
The 10 strands wire made the light bulb brightest because
electricity always needs space to move through wires.
