a. Define the general term used scientists to identify the concept you are studying?
An electric motor converts electrical energy into mechanical motion. The reverse task, that of converting mechanical motion into electrical energy, is accomplished by a generator or dynamo. In many cases the two devices differ only in their application and minor construction details, and some applications use a single device to fill both roles. For example, traction motors used on locomotives often perform both tasks if the locomotive is equipped with dynamic brakes.

b. Additional terminology: What key terms that are used by scientists explaining this concept? Provide terms and definitions for each.
Electromanetism:

c. Diagrams and graphs you found that help explain this concept
An a electricmotor is something that is used in alot of things, wlakman,CD players,DVD players and many other things those were just to name a couple.

d. List your sources
How stuff works.com/walkman www.google.com/walkman www.ask.com/walkman

Design and perform a scientific experiment that illustrates how one the concepts works.

a. What is the “testable” question that the experiment is trying to answer?
A tesable question that I am trying to answer is that it's easy to build a motor using only a 2 wire and a battery pack.

Describe how you will test the question above. Provide a diagram or photograph of the experimental setup.

b. Identify the VARIABLES (independent, dependent, and controls) being measured, with an explanation of how you will measure each of them.

Identify the Independent variable.
How many numbers of coils will affect the speed of the motor in three different trials.

How will the independent variable be measured?
It would be measured by kepping a number count of the number of coils I made around the battery.

Dependent variable: The dependent variable is the average times the coil spins around.

How will the dependent variable be measured?
The dependent varaible will be measured by minutes and by how many times the coils turn.

Control(s): The size of each coil should be the same size.

Why are these control(s) necessary? So that I don't get anything mixed up with my results.

c. Perform the experiment and organize your results (data) in a way that someone else could easily understand. Perform enough TRIALS to ensure you have reliable data. Use a table if necessary.

d. Your conclusions. Do your results lead you to infer an answer to your “testable” question? Why/why not? Explain thoroughly using your data to support your claims.

This is the average out of three trials that I did.

Number of coils used	Average numder of times the coil spined around
5 Coils	109 times around
10 Coils	111.333 times around
15 Coils	96 times around

Yes it was easy to build a motor out of 2 wires a batterie pack a coil and a magnet. But it was hard to make the coils spin because at first I had a small magnet when i needed a bigger magnet to make the coils spin.
e. A list of further questions you still have after performing the experiment.
I have no further question after performing my experiment.

k. Graph your data if appropriate (if graphing doesn’t make sense for your experiment, use another VISUAL method for showing your results). Include your graph on your blog with the following analysis: (1 pt)

i. In words, what does this graph tell you about the relationship between __the Number of coils and the Number of times the coil spins per minute? (1 pt)(independent) (dependent)

ii. If x represents Average # of times the coil spins per minute and y represents_Average Number of coils, the equation for this relationship is:_Is non applicable because I would need more points on the graph. (1 pt, if applicable)

v. How might your results be innacurate? What possible errors could have occurred that would lessen your confidence in your results? (1 pt) I did not count the number of turns correct.

vi. How might you change the experiment to reduce or eliminate these errors? (1 pt)
Use something to help count the number of times the coil spins.

l. Your conclusions. Do your results lead you to an answer to your original “testable” question? Why/why not? Explain thoroughly using your data to support your claims. (1 pt)
It is not hard to buld a motor but it is not easy you just need to take your time on making the motor spin.

m. A list of at least three further questions you still have after performing the experiment. (1 pt) One question that I have is that is there any other way to buld a electric motor.

n. How does your experiment connect to the gadget you took apart? Explain in atleast one paragraph. (1 pt)
My experiment connects to my gadget because my gadget had an electric motor in it so that made me want to try and make my own electric motor.

p. Include a bibliography that shows all your sources. (1 pt)

The city has become a popular city for blogging because "more than 6,250 independent sense of empowerment". Blogs are at the homes in the new york city spirit of doing things yourself.
I personaly think that blogs are a waste of time and effort.

2)What motivates people to keep their own blogs? Use at least one quote from the article to provide an example. (use the Blockquote tool in your toolbar to indent the quote.
The thing that motivates people that use blogs are mostly "bloggers in this town catering to every interest, written by everyconceivable kind of person"

3)Choose one New York-based blog from the article that you find interesting, and give a paragraph summary of what the blog is about. Who is the author? How long have they been blogging? Why do they blog? Inside your paragraph, provide your readers a link to the blog.
There is a blog that I found interesting it's " The Assimilated Negro Blog ".com.
He bine blogging since september 2005. He is a blck man that blogs about blacks and whites.

4)Optional fun stuff:

a) Register your blog at nycbloggers.com This will probably result in visitors and comments on your blog.

1.Your assignment is to post web definitions for the following words:

electric circuit: Electrical circuit is an interconnection of electrical elements such as resistors, inductors, capacitors, diodes, switches and transistors.

electrical conductor: Electrical conduction is the movement of electrically charged particles through a transmission medium. The movement can form an electric current in response to an electric field.

electrical insulator: An Insulator is a material or object which resists the flow of electric charge.

Make sure to include your sources. I got my definitions from ask.com

2. How can YOU define these in your own words based on our experiment with batteries, bulbs, wires, and different materials? How can you test to determine whether a material is a conductor or an insulator? How do you know when a circuit is a CLOSED circuit?
If you are trying to light a bulb using two wires,1 battery, and a bulb, and you attach 1 wire to one side of the battery and the other wire to the other side, the bulb will light, because youwill have a closed circuit. If you take it apart it will be a hole in the circuit which is called an open circuit. You can test if it is conductor by putting it where there is an open circuit and if the light bulb doesn't light it is not a conductor, it's a insulator.

3. How do these concepts apply to your object? What parts are made of conductors? Insulators? How did you know? Are any circuits are present? How can you tell? Use pictures to explain, if you want.
My object is an walkman tape recorder.The motor in the walkman is an conductor. The battery it uses is a conductor.An insulator in the walkman is the rubber covering all the wires, the hole cover of the walkman.

4. What do you think a semiconductor is? Predict the meaning....Then look it up. Are there anny semi-conductors in your object. Where? What parts are made of semi-conductors and what special roles do they play? I think that a semiconductor is something is both an insulator and conductor at the same time.
Semiconductor:
A semiconductor is a material with an electrical conductivity that is intermediate between that of an insulator and a conductor. A semiconductor behaves as an insulator at very low temperature, and has an appreciable electrical conductivity at room temperature although much lower conductivity than a conductor. Commonly used semiconducting materials are silicon, germanium, gallium arsenide and indium phosphide.
One semiconductor in a walkman is on the circuit borad which is a little thing called integrated circuit.
I got the meaning of the word semicondctor from Ask.com

1) Who are the Amish and why do they avoid certain technologies?
The Amish are a small group of imagrants that settled in Lancaster county,Pennsylvania. The Amish is a group that came to the U.S. from Eroupe. They do not use nothing that uses technology, except for disposable diapers,in line skates, and gas barbecue grills.
They think that technology makes a person lazy, cause they see technology as it doing everything for you.

2) According to Howard Rheingold, how do the Amish go about adopting a new technology? What criteria do they use to decide whether or not to allow it?
When the Amish want to adopt a new technology to their lives, they are very techno-selectives
who devise remarkable technologies that fit within their self-imposed limits.
The criteria that they use to get a new technology is when all the Amish get together and debate on weather or not they should use it and there has to be good reasons for using that technology.

3) Do you think we should be more careful about which technologies to allow into our lives? Explain your opinion. How should we decide this? Give examples of positive and negative technologies to illustrate your ideas.
I say that we should not care about what technologys to have in our lives because it is now the future and there are so many new technologys that have been made and we should injoy them.
