Week Three Reflection

In week three we looked that importance of density, which correlate with what we did back in week 2 where we used mass and volume , and it appears that our measurements that we had taken last we is connected and we are using them for this week. We measured the many mass no weight because weight is gravity's affect on mass so be sure to use the term mass, because using weight in this situation is wrong. Anyway back to the class the graph we took on week two had a positive slope meaning as the mass increased the volume increased as well, which means there’s as connection between them. Since there is a connection it means our slope on the graph is the density. I heard someone else say that muscles weighs more than fat in mass. See I have heard that before but I had also heard that from one student shouting that out in class and I knew he wasn't right because I proved by looking it upon the web. It turn out that muscle doesn't weigh more than Fat it's just more dense. Saying something is dense and something that weighs more is much you can make an object more dense without altering the weight or mass and vice versa.  Later in the week we started studying how precise we need to be in our experiments because in the field of science if you’re off by just a little bit than your answer can be completely wrong from then on and you won't be accurate with your answer and there for you have the wrong information. And as many chemists' know, "One wrong calculation can be cause an explosion." Not to say all explosions are wrong calculations ha-ha.  I have to say if I had a job where blowing stuff up was what I did, I'd probably go home happy everyday that is to say no one blows up or gets falling debris or if they got caught in the blast that would be terrible.  I would never forgive myself if I had hurt someone even if it was by accident I wouldn’t be able to forgive myself. I'd only be able to make sure that it would never happen again. The accuracy is essential in science and in life accuracy is needed either to throw a ball or to set off an explosion that doesn't happen to go off in your face. So after all that off topic information, that gives you many reasons why you should be accurate with things. On Thursday and Friday the great Mr. Abud asked us to discuss the different densities of seven beverages water, apple juice, coke, sprite, fruit punch, oil, and Dr. Pepper. He told us to label 1 - 8 them from least to greatest in order of density. I thought sprite would be the least dense if we poured them into a glass of oil if they float or sink, depicting if it the liquid chosen had a greater or lesser density than the oil. I thought it was the sprite because of all the carbonation inside. Turns out I was wrong sprite was actually the 7^th least dense. Oh well I suppose that all I can say about week three until next. Be accurtate!
