MATERIALS
• 3 plastic straws
• 3D batteries
• Electrical tape
•Steel wool pad
•3 small lightbulbs (like for a flashlight)
•Camera to take pictures
•Shoebox for group demonstration

PROCEDURE
1. First put out your 3 batteries on a flat surface.
2. Cut the straws the exact same length as the batteries.
3. Put one straw one the side 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 6 strands of the steel wool and roll them together until they make a wire.
6. Then, take 6 strand on 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 straw 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 bulb.
11. Move the end of the light bulb down until it touches the 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 numbers 1-10(10 being very bright)
14. Do this 2 times for each battery.

Using the scale 1 – 10, with 10 being very bright and 1 not
being bright at all.

RESULTS AND CONCLUSION
The light bulb with 10 wires works better because it has the most wires. The electricity has
more space and more electricity can move through the wires and to the light bulb.
