The Scientific Method Essay Example for Free

The Scientific Method Essay This experiment was performed by using a systematic approach to identify six unknown substances. In the first half of the experiment six unknown substances were observed than measured by determining volume, mass and density. The second half of the experiment the unknown were placed in a test tube and tested for solubility. It was determined that the six tubes contained coffee, potting soil, brown sugar, baby powder, baking soda, and powdered sugar. By the use of the scientific method each unknown subject could be identified. Hypothesis: The contents of unknown samplers are as follows: #1 coffee, #2 potting soil, #3 brown sugar, #4 baby powder, #5 baking soda, #6 powdered sugar. Material List: Digital Scale 50 ml Cylinder Safety Goggles Spatula 6 Test Tubes Magnifier Rubber Stopper Test Tube Rack Marking Pencil Test Tube Cleaning Brush Procedure: The unknown substances were removed from a bag. Next, volume, density, and mass were calculated using small paper boats, a digital scale, and a formula which called to divide the mass by the volume. Then, the texture, shape and appearance of each substance was observed and recorded. Lastly, each substance was tested for solubility in distilled water. Data Table: Calculating Density of Unknown Samples Mass of Unknown Sample (g)Volume (cm)Density (g/cm) Unknown Sampler# 1 = 0.4 1.3 .31 Unknown Sampler#2= 0.5 1.5 .3 Unknown Sampler#3=0.5 1.5 .3 Unknown Sampler#4=0.8 1.3 .61 Unknown Sampler#5=0.6 1.5 .4 Unknown Sampler#5=0.6 1.3 .46 Discussion Based off of observations of color, shape, and texture and smell hypothesis is accurate and correct for unknown samples 1-6. In conclusion based off of color, smell, and texture the hypothesis for unknown substances 1-4 are correct, but based off of these same observations substances 5 and 6 are questionable. Questions: 1. Which of the six measures in the experiment yielded quantitative data? What specifically about the measures was quantitative? Quantitative data is data that can be measured numerically, out of the six measures in the experiment volume, mass, and density would be considered quantitative since these measures can be measured numerically unlike any other from the experiment. 2. Which unknowns are you confident that you correctly identified? What specific test was crucial in confidence? I am confident that I have correctly identified unknown substances 1-4 based off of color,  texture, smell and solubility these measures were crucial in my confidence of my hypothesis. 3. One of the most important and unique steps in the scientific method is the ability to create a new hypothesis if your results do not support your original ideas. What areas in your life, other than in science class, do you think this type of step would be helpful? I am a mother and frequently find myself in the kitchen cooking and trying out new recipes that taste good but are still nutritious (children can be very picky) I would say in terms of a new recipe that I am trying- If my idea is that my children would like to try something new I would test it out by serving it to them, and in the case that my children do not like it I would try again maybe add some ingredients or take something out in hopes that the end result would be for my kids to enjoy the meal while getting all of the nutrition that kids need. 4. What additional test could you perform to assist in the identification of these unknown samples? Melting, boiling, or even chemical test may be performed. 5. Which of the seven tests performed was the most challenging? The most challenging test for me was the shape test, I found this most difficult because although I had the magnifier I still had trouble distinguishing what it was that I actually saw as I was examining each substance, however once I examined each substance individually I compared what I saw and could most definitely see the difference between large and small particles.

Leadership Qualities That Rely on Five Principle Actions

Leadership Qualities That Rely on Five Principle Actions Akhil Reddy Leburu Abstract This paper explains the leadership principles that are proposed by James Kouzes and Barry Posner. The leadership qualities were described as per the five principles followed: Leaders challenge the process, Leaders inspire a shared vision, Leaders enable others to act, Leaders model the way, Leaders encourage the heart. The ethical behavior and social identity are briefly described. Keywords: Ethical behavior, Social identity Leadership Qualities That Rely on Five Principle Actions The five actionable qualities are main roles that leaders should acquire given by the author. Leaders plays an important role in the company who leads the team and assign the tasks to team members per their skills or department. He/she should take the responsibility of the team members. The influential roles that a leader should obtain are given below. We are going to discuss about the five principles that are required for a leader. In this discussion, Im giving real time examples to describe how each principle can be effected on real world situation. Leadership Challenge the Process Inspiring innovation and leading change call for more than process- they require the adoption of a cultural mindset (as cited in Forbes by Mike Myatt). The leader should challenge the foundation if the vision and core values are shaky. Challenging the promise keeps the leader sustainable and deliverable. For example, if the leader is not able to communicate with team members and not able to complete the product as promised to given time, you may be in the trouble. The leader should challenge himself instead of challenging others. Great leaders challenge all the complex things. The leader must assess the information quality gathered and must be credibility in the process. Leaders Inspire a Shared Vision If they [employees] cant see themselves in the picture, then they cant imagine that its a possibility for them. (as cited in Forbes by Carmine Gallo). The leaders must have a clear and perfect vision before inspiring others. For example, the professional athletics visualize the game before the game starts from beginning to end, they focus on gaining the victory. Invite your team members to explore their ideas or thoughts and opinions to be more than a pay check. Nothing extraordinary ever happened without a leader articulating a vision, a course of action says John F. Kennedy. Leaders like Mahatma Gandhi, Martin Luther King and Che Guevara inspire us by being themselves as great speakers who were followed by the public opinion and share their vision to the world. Leaders Enable Others to Act Leaders who Enable Others to Act spread their influence far beyond their physical sphere (says Jody R. Rogers). The leader cannot survive without his/her teammates or colleagues. The leader need to take an advantage of opportunities of team to decode their challenges. Leader should take a responsibility of sharing each other ideas or thoughts to implement new products. The leader should have skills or knowledge on what the team are discussing about and meet their expectations. For example, if a team has a different thought that solves the current problem, the leader doesnt take a chance of referring the problem with the team, the leader may lose the opportunity to get a perfect solution. Leaders Model the Way Leaders live and act by their values. They have clarity in what they believe, and they align their actions with their values. Leaders must set an example by setting the actions with shared values. For example, a car dealer who dominates his market. He is not only the one, the next four car dealers combine and equal up the market where he competes. The leaders must lead a path to next generation by giving a motivation. He/She must be excepting the ideas and thoughts of the team. Leaders Encourage the Heart Leaders give heart by visibly recognizing peoples contributions to the common vision (by Kouzes Posner, 2012). The leader must recognize contributions by giving respect for individual excellence. Leaders follow their heart and encourage the thoughts and get them into the world. They should take the responsibility of the team and give them the requirements and space needed. Conclusion I conclude that the five principles that are proposed by James Kouzes and Barry Posner plays an important role in the leadership challenge process. The leaders must follow the principles that are mentioned in the discussion. I have given a brief description of each and every principle in the paper.

My Miracle :: Personal Narrative Writing

My Miracle "Dad, I need to go to Hailey's to borrow a shirt for school tomorrow," I shouted from the back room. It had been a hard week for me. My cheerleading squad was preparing for a performance, and we had been practicing before and after school. While I waited for an answer from my dad, the game show, "Who Wants to be a Millionaire," sounded in the background. "Dad, I am going to run to Hailey's real quick," I repeated my shout. A reply came: "It's snowing pretty hard, wait for my show to end and I will take you. I am on my way to the store anyway." I looked out the window to see snow coming down pretty heavy. On any other day, I would have argued to leave right away, but for some reason I didn't argue. Ten or fifteen minutes later, however, I decided I really needed to go. I said, "Mom just take me, I have a lot of stuff to do tonight." My mom said she didn't want to drive on the bad roads. "Wait for your dad," she told me. So I waited. Finally, the show ended and we were on our way out the door. The roads were slippery and the snow was coming down hard. I looked out the windows of the car and in my mind, I heard my mom reminding me to slide the seat away from the dashboard. I chuckled to myself that a seventeen-year old would be too small to sit with an airbag, but I was. As I slid the seat back, my dad asked, "Cara is your seat belt on?" I fastened my seat belt and stared at the snow. It was a peaceful night; it felt quiet and serene. It felt good to have a few minutes of alone time with my dad. We were lost in conversation, and before I knew it we were in front of Hailey's house. I ran in and waved goodbye to my dad. I found the shirt I wanted, and played a game with Hailey and her sisters while we waited for my dad. We joked about my mismatching outfit that consisted of doctor scrubs, a football sweatshirt, and snow boots. While we were laughing, I noticed the headlights in the driveway and hurried out. I excitedly explained the game we had played to my dad as we drove away from Hailey's house.

Romesh Gunesekeras Ranvali: A Refutation of Conventional Characterizat

Romesh Gunesekera's Ranvali: A Refutation of Conventional Characterization "Ranvali" serves as a personal reminder. It conveys sadness and regret with the narrator's realization only years after her father had died that she had been mistaken about certain aspects of him and that after this realization, she was unable to try to improve their relationship because he was no longer alive. The characterization of her father is essential in carrying across this sadness and regret because his character - the person of the father, to be contrasted with the qualities of the father, is the preconditions for the narrator's flashbacks. The objective of this paper is to refute the conventional argument that the functional role of a character makes it secondary in importance in a narrative and hence, show "Ranvali" to be a character-centred narrative. The stand that this paper takes, therefore, is that the functional role of the narrator's father makes his character an integral part of the narrative, such that "Ranvali" is a character-centred narrative. Before embarking on the analysis of "Ranvali", it is necessary to introduce three theories surrounding the notion of character in narratives. According to Aristotle's theory of character, a distinction can be made between an agent - a person who performs actions and is necessary, and, a character - "something that is added later and in fact, not even essential to successful tragedy . . . Added later . . . if at all" (qtd. in Chatman 109). In "Ranvali", the narrator's father is an agent because of his importance to the story, which will be elaborated upon later. However, he will be constantly referred to as a character in this analysis so as to be consistent with the terminology throughou... ...ves. By superimposing Todorov's theory of character, the second inference - this secondary importance of characters in narratives implies that such narratives are not character-centred, was made. The first argument has already been refuted in the previous section where the functional role of the father is shown to cause him to be of primary importance in "Ranvali". As for the second argument, it has been refuted along with the refutation of the first argument, as well as, the satisfaction of both of Todorov's criteria. The conclusion, therefore, is that "Ranvali" is a character-centred narrative, where the deceased father is a primary character.
