School Up Till Now

First two Weeks of School! 

During science class we have learned different things up till now including concepts that include Electricity. Our first task this year was to build a simple motor. At first I was confused not knowing what exactly I needed to build, but after I accessed google.com, all my questions were answered! The hard part was to chose what type of motor I needed to build, which one was I going to choose? What materials should I use? I looked at the following websites for help, and to help me get the entire concept of the motors;

• http://www.simplemotor.com/
• http://www.oblatos.com.br/firewall/denied.htm
• http://www.sfu.ca/phys/demos/demoindex/eandm/em5k/simple_motor.html

These two websites help me a lot to know more information, what materials to use and they answered all of my question! The picture of a motor that inspired me to bulid my motor was in the first website, very much like this one:

Although mine had a different layout with the batter, the wire and everything was inspired by his image, and this one too:

     I had to go search for all my materials with my father, and we had to take the rubber layer around the copper wire off, and then put everything together. It was really hard to get everything just right, and I had mager difficulties to make the circule copper wire spin 360 degrees, min only spun 180 degrees. I personally did like to make the motor, and it was fun to play with it, and to try to fix it, it gave my head something to think about. 

     When the time came to show and bring your motor to class I was really excited to show mine, and excited to see what my class mates did. I saw all types of motor, different designs, and some worked, and a few didn't. One problem that everyone had was that our motors battery would last very little because we didn't have a resistor in our circuit. 

   All the different parts of a motor included the battery, the wire, magnets, and something to hold it together (rubber band, paper clips, etc.) The different parts of a circuit are; a battery, wire, resistor, receptor (light bulb), and a switch (which in our motors our switches were just us disconnecting the wire off the battery). A perfect picture of a circuit is the following, keeping in mind that there is also a parallel circuit! 

    Afterwards we learned how it works, and we magnetized a nail, and we learned all the parts of a wire, a circuit, and over all I enjoyed this unit, although at first it was still a little confusing, I managed to understand. If you have nothing to do, go ahead and build your won simple motor, or go for a challenge!! Please feel free to comment bellow!
