ALLISON GUO Does Electricity Flow Better Through Thick or Thin Wires? ! The purpose of my science which light bulb shines brighter. To project is to find out if electricity do this, I will need materials: 2 batteries, light bulbs, tape and straw. travels through thick or thin wires unused new flashlight bulbs, thin ! better. My hypothesis is that I think copper wire, thick copper wire, electricity will flow through thicker electrical tape, plastic straw, 2 there were results. It seemed that the light bulb using the thicker wire wires better, because the thicker unused “D” batteries and scissors. wires give more room for the ! The dependent variable is shined better. The thick wire was about 2 mm. thick, and the thin one electricity to flow freely. what will be measured during the was about 1 mm. thick. I tried ! In the procedure, Iʼm going experiment. In my experiment, the to make two short circuits with dependent variable is how much lighting the light bulb 5 times, and each time, the light bulb with the copper wires, two light bulbs, two light the light bulbs are going to batteries and try to light the light give out. The independent variable thicker wire shined brighter. ! In conclusion, the data bulb at the end. Iʼm going to do this is what will affect the dependent supported my hypothesis, light with two light bulbs and circuits, variable. The independent variable one for the thick wire and one for is the different thickness of the travels through thicker wires better, because the thicker wires give the the thin wire. The copper wire will wires, that is going to affect the connect to both the light bulb and brightness. The controlled variable electrons more room, so it can flow freely. This applies to the real the battery. Then, Iʼm going to is the variables held constant. For world, because when you want to touch the end of the bulb to the my experiment, the controlled negative end of the battery, and see variable is that Iʼm using the same light a light bulb, itʼs going to shine brighter if you use thick wires. After I did the experiment,
