Does electricity move better through thick wires or thin ones?

HYPOTHESISWe think that 10 wires will work best because more electricity can pass through.

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

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.

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.
