Static Electricity or Electrostatics Peter Jeschofnig, Ph.D. Version 42-0278-00-01 Lab Report Assistant This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor. Observations Questions Part 1 …show more content…
Run the cup lightly over the back of your arm. What do you observe and/or feel happening? * I feel my hairs from my arm rising and like a tickle and I observed my arm hairs going up while the cup was on my arm. 2. Bring the Styrofoam cup close to another person's hair. What do you observe? What conclusions can you make regarding charged Styrofoam? - Static is being seen the cup was rubbed with my hair and the reaction is there. My hair goes up. Question 1 Question 2 Part 4 1. Rub an inflated balloon with the fur and try to stick it to different surfaces. What can you make the balloon stick to? Does it stick better to some surfaces? Why? * According to by surroundings the fur does not make the balloon to be attracted to anything. With my hair only a bit does is make it rise but not really. It can be because the rabbits fur is thick compared to other charging objects. * 2. Rub an inflated balloon against your hair and then try to stick it to the same objects you used for Step A. Does rubbing with fur work as well as, better than, or worse than if you rub the balloon against your hair instead? * It’s basically the same only that when I rub it with my hair and leave it in my hair my hairs do rise unlike the rabbit fur it did not make my hairs rise. 3. Bring the charged balloon close to the paper scraps from Part 2. How does the rubbed balloon
Main Point Three: The actual twisting of the balloon is what makes the shape of the animal.
Designing your own experiment 1. Make an observation: When a balloon is rubbed on someone’s head the hair on the person’s head will stand up, and if the balloon is later placed on a wall it will remain there for a certain amount of time. 2. Ask a question: Do different hair colors have different effects on static electricity? 3.
The purpose of this experiment is to find out which brand of paper towel, Decorator or
Next, during the experiment, it was observed that the hole in the lifesaver was not big enough for Sam to go through it. It was also observed that Sam and the lifesaver were both very fragile in the sense that they could be reshaped or stretched easily. In contrast, during the lab, it was observed that to go through with the procedures four paperclips are needed. Further, into the lab, it was noticed that the lifesaver needed to be stretched at least 4 more mm for sam to go through the lifesaver. The hypothesis was proven to be correct because after reshaping the paper clips from their original form it was
The final stage of our Rube Goldberg was the balloon popping. That was caused from the dominoes hitting bigger objects in the chain and the last object had a pin attached which popped the balloon which made elastic potential energy and also sound energy take place. The elastic potential energy took place as there was a balloon and balloons are made from rubber, latex, or a nylon fabric. Which when balloons pop cause a reaction which not only produces elastic potential energy but also sound energy from the popping
There were few materials needed to conduct this experiment. All we used was, a cork, rubber band, and a target. The cork was two inches high. The rubber band was three inches long without being stretched. Last the target was about six feet above the ground. All these materials were constants. This makes the experiment less complex. The only variable would be how each person shot the cork.
In this experiment I am going to get really close to someone while we are talking and see their reaction. I am also just going to sit next to someone that I wouldn’t normally sit next to and I’m not going to say anything I am just going to sit by them and see what they do. I will also walk next to a stranger and get pretty close to them. When I see the reactions of the people that I am testing I am going to measure it with how fast they react, if or what they say, how awkward they act and if I get punched or not.
Other causes may be friction from clothing or necklaces, causing them to be primary causes but can develop to secondary causes if picked or rubbed to
In the rare case you ever have a monster magnet and an Apple iPhone you are willing to damage a little bit, by all means, rub it over the hte magnet. According to the video, it is a relaxing sensation unlike anything else. Is there a scientific
Balloon could pop startling others causing them to drop, spill or bump something leading to other safety hazards
“That looks odder than the video showed,” Talisa commented, slightly confused. The air-filled balloon was placed around the lid and the CD disk glued underneath to create a platform in which it would hover—not that it would work. Sighing, Talisa got up to stretch her long legs before testing the homemade experiment, which was the easy part.
III. Start with the Red shirt. Put it on. Walk up to a stranger and ask him this question Would you believe me if I told you the other side of this index card was blue? Ask 10 more people and record your findings in the chart you drew. Make sure to have parental guidance while conducting this experiment.
Procedure: When performing this experiment, make sure to tie long hair back, wear appropriate eyewear, and avoid touching the hot plate. A beaker
Procedure: 1. All materials that were needed for the lab were gathered (aluminum foil, aluminum information sheet, scissors, electronic balance, calculator and a ruler). 2. The aluminum foil was cut either a square or rectangle. 3.
