Week 4

Today we are going to revise and collect all the materials that we are going to use the next time. We had the nucleuses (which are going to be nails with different width) from before. Today we are also going to decide the width of the copper cable and the batteries that we will use.
We have finished our calendar from today untill the 15th of November. The procedure has been done and the background info has been partly done.
This is our calendar:

We have finished criterion A:

"A. Formulación del problema de investigación.

. El problema de investigación está bien definido y se han identificado todas las variables pertinentes."

We have decided to investigate the factors that influence the power of a magnet. We are going to make different magnets and we will change one of the three variables of a magnet at a time.

 First we will change voltage leaving constant the diameter of the core and the number of turns of the copper and then we will make the same but changing the diameter of the core while leaving the rest of the constant controlled. Finally we will change the number of turns in the copper wire while leaving the rest constant.
