Our task is to charge different material of rods with some fabric and find out the strongest pair of conductor.
Control variable: stand
dependent variable: piff
independent variable: different materials of rods and different materials of fabric
|Silk||No effect||No effect||Lightly attracts||Slightly repels||No effect||Slightly attracts||No effect||Slightly Repels|
|Cotton||No effect||No effect||Attracts||Slightly attracts||No effect||Strongly attracts||No effect||Slightly attracts|
|Polyester||No effect||No effect||No reaction||No reaction||No effect||No effect||No effect||Attracts|
|Fur||Slightly attracts||No effect||Strongly repels||Strongly repels||No effect||StronglyRepels||No effect||Slightly repels|
|Plastic||No effect||No effect||Slightly Repels||No reaction||No effect||Very slightly attracts||No effect||StronglyAttracts|
|Wool||Slightly attracts||No effect||Slightly attracts||Strongly attracts||No effect||Somewhat attracts||No effect||Slightly repels|
Ebonite and plastic is the strongest conductor at attracting.
Lucite and fur is the strongest conductor at repelling.
How did it happen?
The piff get attracted from the charged rod because the piff got some electrons from the rod and both of them have negative charge.
The rod pushed and repelled the piff because they’ve got different charges.
I think I had very great experience when I was collaborating with Claire, Samira and Theodora. We had equal workload and everyone was on task, no one was playing with their hone during the experiment. Samira and Claire collected the result and made a clear table. Theodora and I did the experiment with different materials. I felt so proud of our work and results.
