Confidence Is Key.

After spending a day being a participant observer in Geology 170 known as Earth Shock, I now know William Mangrums’ COMP 250 class has better prepared me for other college courses.  For most kids in geology being awake and present at ten a.m. on Monday, Wednesday and Friday is not a priority. On February 16th there were at least four people who walked in late. Once class started, the professor turned off the lights creating a very dark room, and began the lecture which happened to be watching YouTube videos on volcanoes. About halfway through the video, I began to look around the class to see what students were doing. Half of the forty-seven students were on their phones, another fourth of them were zoned out or asleep and studentsthe last quarter of them were actually paying attention. This kind of behavior would not be tolerated in Mangrums’ class, after being in Earth Shock and comparing my behavior with others in the class, I have noticed myself becoming more focused and on task. Not to mention actually awake and ready to speak when called on. The class also forms groups to work on in class projects, the first time we were asked to work together, I was timid and listened rather than participated. Thanks to Mangrums’ class, I now have the confidence to initiate conversation and begin working. Unlike a lot of college courses Earth Shock is a pretty laid back class but, that doesn’t mean the students should be any less present because it is easier. On Monday February ninth a surprise quiz was given, the test was fairly difficult but, because I had been paying attention in class I new the majority of the material. Due to Mangrums’ class, I now have what it takes to be successful in any college course if I set my mind to it.

Bull Sharks: Bull or Shark?

Bull-SharkCarcharhinus Leucas or Bull sharks are large powerful animals who lurk in the oceans murky waters. Bull sharks are stalky in size with blunt noses, small eyes and triangular saw edged teeth. Their dorsal side (upper) of the body is grey in color and their ventral side (lower) of the body is white in color. They are found throughout the world, a sympatric species meaning they come from a single line of ancestors and have inhabited the same geographical region over time. The sharks breed by internal fertilization, and can give birth to 1-13 pups after about a yearlong gestation period. One biological aspect that is interesting about the Bull shark is their habitation. Bull sharks inhabit shallow waters in bays, estuaries, rivers and lakes. Unlike most sharks, they have the ability to swim in fresh waters because they are able to adapt the filtration of fluids in their body by the process of osmoregulation.tibu1am5 Bull sharks are also one of the most aggressive sharks, alongside great white sharks and tiger sharks, all of which have been known to attack humans. Since they hunt their food in tropical, shallow, murky waters, often times attacks occur where people swim or fish recreationally. Bull sharks are known to be more docile in clear water habitats, meaning the sharks are less aggressive when the water has clear visibility. The Bull shark gets their name from not only their blunt nose but, they head butt their prey before attacking. Although the Bull shark is not considered an endangered species, their numbers are dwindling due to shark fishing for their hide, oil and meat.
