Journals:
I've decided to commit to the journals due to the reliability and ease of them.
Journal 1: Setting up the experiment. Not much change in temperature. Trying more balls next time. The temperature seems to be unaffected with the amount of current balls, so we shall increase the number to see if the amount affects the temperature change at all.
Journal 2: With more balls, the more significant change in temperature. Seems as the number of balls correlates directly with the temperature. It was only a small change, by the hundredths, but its still a significant change. More than the last attempt we had made. There seems to be a correlation between the amount of balls and the heat coming off them as I rotate the tube.
Journal 3: We attempted once more with even more balls, the temperature change is now significantly noticeable. Still a small change but more noticeable than the previous trials. Now we are convinced that the more balls the more heat is given off. I think it has to do with the amount of heat energy that is being given off by the amount of balls, the more balls, the more heat given off.
Journal 4: With the maximum amount of balls the change is now a lot more noticeable, almost to a full degree. The heat is almost three times of what we had began with, with the maximum balls the kit had come with. The heat energy being given by all the balls is collected and transferred, being amplified by the amount alone.
Journal 5: Tried turning the tube faster now, just to see if the temperature change would increase at all. It worked to some degree. Only to the hundredths again, but it is yet another way to increase the amount of heat energy being given off.
Journal 6: Have now had 4 separate runs, there is now enough data to come up with a conclusion. Will take a look next time we return for the conclusion.
Journal 7: We had found that with more balls, comes a greater change in temperature; more heat is produced. As mentioned in Journals 3 and 4, the more balls, the more heat energy there is to be transferred.
