Home Electroscope
Hello Steemian friends :) How are you?
Today I will show you how I did my science project that our physics teacher sent me as an evaluation in my high school.
And it is an ELECTROSCOPE, but before seeing, let's see what it is and how it works...
It is an artifact that serves to observe if a body is electrified and approves, if affirmative, determine its sign. When we bring an object with electric charge to the electroscope, it has some little laminates that if separated, means that the object has the same charge of the electroscope therefore they will repel, otherwise, if the little laminates are joined, it means that they are of different charges and for that reason they will attract.
Very well, since we (I am talking about my classmates) were not going to do an electroscope exactly like that, our teacher sent us to do a homemade electroscope, and then, here is the procedure of how I did it.
1. We will need a glass or plastic container with its lid, aluminum foil, copper wire (can be a cable) and a balloon.
2. To the lid we open a hole.
3. To the hole in the lid we put the copper wire (they can do it as I did, they can do it with a straw or they can put it on their own, but it is better to put something to make it an insulator) and if you want, the wire at the top we do a spiral, but that's optional.
4. The aluminum foil we will use it in two ways, one is to make the metal little laminates that will be tested if there is electric charge or not and the other that is optional is to place it on top of the spiral that I made previously so that there is more electrical attraction.
5. When closing our container, what is missing is to test our electroscope.
6. To know if the electroscope works, we grab the balloon and rub it through our hair, just like we did as a child, and we will bring it closer to the tip of the copper wire (where is the spiral and aluminum foil), if the little laminates moves our electroscope works, just like mine did.
And that's it! In just 6 steps you can have your own electroscope. I hope you liked mine and of course my post See you next time!
