Lab Report on Osmosis and Diffusion Biology 1, Period 3 March 15, 2010
Lab Team: Jason Perez, Kicia Long, Chris McLemore

Purpose:
The purpose of this lab is to observe the acts of passive transport: diffusion and osmosis in a model membrane system. The experiment will show how molecules in solution move from areas of higher concentration to areas of lower concentration. The model membrane is dialysis tubing.

Materials Used 2.5 cm dialysis tubing 15% glucose solution glucose test strip 1% starch solution distilled water Lugol’s iodine solution

Procedure:
Each member of the lab group will complete the procedures independently 1. Obtain a 30 cm piece of 2.5-cm dialysis tubing that has been soaking in water. Tie off one end of the tubing to form a bag. To open the other end of the bag, rub the end between your fingers until the edges separate. 2. Place 15 mL of the 15% glucose/1% starch solution in the bag. Tie off the other end of the bag, leaving sufficient space for the expansion of the contents in the bag. Record the color of the solution and weight of the bag in a data table. 3. Test the 15% glucose/1% starch solution for the presence of glucose using a test strip. Record the results in the data table. 4. Fill a 250 mL beaker or cup two-thirds full with distilled water. Add approximately 4 mL of Lugol's solution to the distilled water and record the color of the solution in data table. Test this solution for glucose and record the results in data table. 5. Immerse the bag in the beaker of solution. 6. Allow your set-up to stand for approximately 30 minutes or until you see a distinct color change in the bag or in the beaker. Record the final color of the solution in the bag, and of the solution in the beaker, in data table. Weigh the bag and record the weight. 7. Test the

...Consider the importance of essay writing to academic practice in the social sciences, with particular reference to Priest (2007) and Ballard and Clancy (1988). Draw on SSK12 materials and your own experience. In this essay I have stipulated the importance of essay writing in the social sciences outlining knowledge development, bringing fourth the importance of linguistics with the understanding of cultural laws and language within the areas of social science, showing the importance of jargon language with comparisons between two subjects and what is expected from the student in the governing of essay writing. I have also reflected upon essay writing from a teachers perspective, noting the expectations a teacher looks for in essay writing, and adding my perspective with an understanding of the essay cultural system. I have also outlined my experience with the understandings of cultural expectations in disciplines and essay writing concerning linguistics. The importance of essay writing academically in the social sciences is structured in the knowledge internalization, the student writes about the facts that have been a subject of a lecture or read in an article, furthering the knowledge and retention of a given subject, “learning to write essays is empowering. It is learning to take one’s place in the world of ideas” (Priest, 2007). The importance also lies in the intellectual development of a students knowledge...

Learning and Knowledge

...Running head: KNOWLEDGE DOMAINS AND DOMAIN LEARNING Knowledge Domains and Domain Learning Liliana Maggioni and Patricia A. Alexander University of Maryland In press Keywords: discipline, domain, learning, history, knowledge, mathematics, reading, science, writing. Abstract The roots of current disciplines and domains of study reach well back in history. An exploration of their development shows that these areas of knowledge have not only reflected cultural changes but have also influenced societies, especially through formal educational systems. Besides being characterized by their focus on a particular part of the world, disciplines are also distinguished by a specific way of thinking about their respective domains of study. Psychological research has identified several features of these pathways to knowledge (e.g., reading, writing, history, mathematics, and science) that generally define the landscape of academic practice. Although educational psychologists’ interest in how knowledge develops within specific domains has fluctuated across time, formal education throughout the world is organized around particular fields of studies and students soon come to characterize their experience of school in terms of subject matters. Thus, in education, domains seem to make a difference. The term knowledge domain refers to the part of the world investigated by a specific discipline. In other words, the domain can be characterized as the object (e.g., plants...

Civilization

...The definition of civilization is an advance state of human society that shows high levels of culture, science, industry and the government have been reached. Specifically the state of cultural development at which writing and the keeping of written records is attained. Humanities by definition is the documentation of human being through stories, paintings, religion and beliefs. The stories around the campfire, family heirlooms that come with a story, the journaling of our experiences and lives all become a form of humanities that is passed on to the next civilization after it. Humanities is shown through art and paintings, but does not stop there. The paintings not only tell a story in picture, but document the evolvement in skill of art with techniques and tools. The documentation of beliefs allowing for the development of religion organized societies, giving order or sense of normalcy in the burial of bodies and or praying to a god. In religion art made its presence through sculptures used in religious content. These definitions of humanities were first present in the First Human Era which has become the 1st example on record. This era marks the beginning signs of humanities and the form in which we measure humanities by. It later developed during the Mesopotamia Era into more with the beginning signs of humanities in science and culture.

...The Challenge of Communicating Science to the Public By Charles R. Chappell and James Hartz Developments in science and technology affect virtually every aspect of our lives, from our physical health to the kinds of cars that we drive. Improvements in technology have contributed substantially to increased productivity in U.S. industry. Yet in recent years, political pressures to balance the federal budget have eroded the proportion of the budget devoted to basic research, the underpinning of scientific and technological advances. Scientists have understood the potentially debilitating consequences of this, but many citizens have not. President Clinton's budget for fiscal 1999 would begin to reverse this trend, if Congress accepts his proposals, but our information media still need to do a much better job of helping scientists communicate the substance and importance of their work. As visiting scholars at the Freedom Forum's First Amendment Center at Vanderbilt University, we conducted a survey of 2,000 journalists and editors and 2,000 scientists and engineers to determine how the two groups felt about each other. We also wanted to find ways to improve their relationship and thus increase the amount of accurate and useful scientific information in the media. The results of the survey, published in our recent report, "Worlds Apart," showed that neither scientists nor journalists think the media do a good job of explaining science to the public. We asked both groups to rate...

Aristotle Research Paper

...Aristotle was an ancient Greek philosopher and scientist that helped form the scientific knowledge and theories we have today. Being the “first real kind of scientist” Aristotle had a huge impact on the science world. Without the studies of Aristotle, many of the scientist in the time after him would not have been able to form the theories and beliefs they developed by looking at the work done by Aristotle. As one will see, Aristotle spent most of his life studying, teaching and writing; making him one of the most famous scientist that lived. Aristotle was born in 384 B.C. in northern Greece in a place named Stagira. Both of Aristotle’s parents were born into medical families. It is commonly thought that Aristotle was raised by close family members, considering both of his birth parents died while he was a young child. For the short time that Aristotle had to live with his birth parents, his father taught him about medicine. He attended Plato’s Academy, at age seventeen, located in Athens. He stayed at Plato’s academy for twenty years as both a student then later a teacher. During his time here, he met Pythias, his...

Sport Social Issue

...Sport and Social Issues: Researchers vs Journalists Social science researchers and media journalists use different approaches to sport and social issues. An example of this can be seen in the “publication journalism” practice by O’Neill and Mulready (2014) and the media article by Lopiano (2004). In the social science research publication more relevant subject knowledge, statistics and logic is included along with a high level of subject specific language and academic writing. This is in contrast to the media article where the journalist may find it difficult to apply academic writing as the target audience may not be as well educated. In conclusion to this, research journals are aimed at people with an interest in a specific area and who have adequate knowledge of the subject whereas media coverage is aimed at the general public who may be reading about an issue for the first time, thus meaning the author may have to include suggestive or sympathetic language styles. Another difference between the two approaches is the use of references, media publications do not always include previous research and cite specific work. Media articles, for example in appendix 1’s “Low Female Sports Coverage In Media Due to Gender Bias” are simpler written by using more emotive language to engage the reader whilst using a modest range of vocabulary so the general population can understand the point being made. This is a divergence to scientific publications which are more scientifically targeted...

Galileo Research Paper

...answer to the Astronomical Balance. Even if they never ended up with a decision there was an even bigger controversy at the time, which was the controversy over heliocentrism. Most of the people believed in the geocentric view, which was that the earth was the center of the universe and that all “heavenly bodies” orbited around the Earth, but Galileo defended heliocentrism, he supported the idea in which the sun does rise and set, and argued a different movement of the earth. In the year 1615 Galileo's writings on heliocentrism had been submitted to the Roman Inquisition, which defended the ideas of Copernicus, but the Inquisition did not like this so, Galileo was later sent to Rome to defend him and Copernican ideas. In 1616, the Inquisition order declared heliocentrism to be "foolish and absurd in philosophy, and formally heretical since it explicitly contradicts in many places the sense of Holy Scripture."(94). As time went on Pope Urban VIII had asked Galileo to continue writing, “Dialogue Concerning the Two Chief World Systems”, with...
