I. After Edison lost the war of the currents he continued to work as an inventor. Also, his child, the DC is still an important part of our everyday lives. This is because anything that runs on a battery runs by DC. Edison also advocated the use of AC for the electric chair and for torture.

II. This past week in class we finished up our wind turbine labs. We white boarded our results and discussed what further steps we could have taken in the future to make our results more reliable. The biggest drawback of our experiment was that we did not have enough trials, so we could not tell if our results were typical or not. On Friday we started to talk about electrical circuits. We played around in groups testing different materials to see if they were conductors or insulators. We can to the conclusion that metals are conductors and non metals are insulators. A lot of the activities we did in class seemed very simple and elementary. I would have preferred to have done more engaging activities with electrical circuits and conductors.

III. For next week I would like to find out what the formula is for calculating standard deviation.
