Experiment Title: Testing if the distance I walk makes the static electrical shock less or more.
What was the purpose of your experiment? Provide a brief description of what you were hoping to learn, discover, or study.: The purpose of my experiment was to see if I can transmit the static electricity to my mom over long and short distances.
What was your hypothesis?: My hypothesis was that the farther I walked the less the shock would be.
What materials did you use in your experiment? List them all.: The materials I used were:
1. Van de Graaff
2. my mom
What procedure was followed? Provide a brief description of the steps you followed during your experiment.: The procedure was:First, I put my hand on the Van de Graaff generator for 5 seconds. Then I let my hand go and touched my mom while i was still on the metal platform. I made note of if the shock was strong or weak.
I followed this same step one more time, except I took 2 steps on the carpet before touching my mom.
Then I repeated the same steps, except I took 5 steps on the carpet.
What were the results of your experiment?: The results of my experiment were that the farther on the carpet I walked, the less strong the shock was. On the generator’s platform, the shock was much stronger. After walking 5 steps, there was barely any shock.
What is your conclusion after conducting the experiment? Was your hypothesis correct or incorrect?: My hypothesis was correct, but my logic was not correct. My logic was that the shock would wear off after a little while so it would stop. But that was not correct. I know this because then I took 10 steps without leaving the platform, and there was still a strong shock.
Spend a few minutes learning about the scientific princples involved in your experiment. Write 3-4 sentences about what you learned and how it relates to your experiment.: I learned that static electricity exists because electrons of atom jump to something else leaving the atom imbalanced. So, for example, if you touch a Van de Graaff, you become too positively charged. Then if you walk on the carpet, the carpet attracts some of extra positive charge. By the time I got to mom, there was little positive charge left in my body.
