Improving the Aim!!

Today while doing my blog, my sister helped me to think of how i could improve my aim a little bit more, but it would still have the same concept.

           BEFORE (I changed my aim):  Which genre of music will help you concentrate better. 

NOW: (This the aim for the experiment:)" Today, most teenagers owns mp3 player or Ipods, which they used to listen to music. I decided to research this topic to investigate how music can affect the concentration of the human brain in teenagers"
