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

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

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…...

...The importance of science education for children Published 03/11/2008 Science Communication 17 Comments  Tags: Science Education One of the features of wordpress is a list of what web searches have led people to your blog (or at least hits anyway) and they themselves can be fascinating glimpses into what people are interested in or what information on (mostly Tyrannosaurus and Jurassic Park). A recent one was the title of this post and it is a very interesting question (precisely it was “what is the importance of teaching science to children?”). Apart from the fundamental answer (well, everyone should know a bit about biology, chemistry and physics, much as they should know a bit about history, geography, art and maths) it is a good question. What does science bring to the table? It’s hard to put in specific terms, but science as a concept (as opposed to just learning facts and theories, or heating stuff in test tubes) has some nice ideas to offer that would be useful for many people to learn and would be useful throughout their lives. Concepts such as logical deductions and inference, parsimony, and not accepting arguments (or dismissals) based on authority but from evidence, and scepticism would all be handy. Teaching someone how to appraise and evaluate conflicting evidence and any bias in that evidence would be useful ‘life skills’ for pretty much everyone. Let’s face it, it ultimately comes down to trying to spot patterns, work out reasons for them, and to spot......

...The writing process begins the minute you get a writing assignment—whether you are writing a book, an essay, or a single paragraph. It involves all the activities you do, from choosing a topic to turning in a final draft. The phases, or stages, of the writing process are prewriting, drafting, revising, and editing. Prewriting Prewriting refers to all activities that help you explore a subject, generate ideas about it, choose a specific topic, establish a purpose, and analyze the audience for your paragraph or essay. Your mission at this stage is to stimulate your thinking before and during the act of writing. Every time you think of a new idea during the writing process, you are prewriting. Drafting When you have lots of ideas to work with, you are ready to start drafting. Drafting involves writing down your thoughts, developing or expanding some ideas, organizing your thoughts to reflect your purpose, and writing a first version of your paragraph or essay. To start on your draft, you may want to spread out your class notes, journal entries, and other prewriting notes so that you can start to string your ideas together. This is the time to keep your thoughts flowing without worrying too much about grammar, punctuation, mechanics, or spelling. Revising As you may suspect, the process of writing is not finished with your first draft. You should always revise your work to make it stronger and better. Revising involves rethinking your content and organization so that your......

...relates all to male readers, whose average reading scores lag behind those of women by 13%. And even though higher educational levels do score more often as proficient readers, prose literacy scores have been declining among all educational levels.   Comics can nudge children toward reading for fun and reading more often, and thus to higher reading proficiency. In one study of seventh grade boys [7], 54% of heavy comics readers in lower income families and 65% of heavy comics readers in middle-class families read daily for pleasure, percentages that dropped to 40%/35% for occasional comics readers who read for pleasure, and dropped further to 16%/33% for non-comics readers. Another study [8] of common and uncommon words in speech and writing showed that comic books contain more “rare words” than average books, adult-adult conversations, adult television shows, and children’s literature. Therefore, comics reading can help children develop their literacy vocabularies, and Jim Shooter’s “bouillabaisse” story is probably not unusual.   Certainly comics appeal to young people, especially boys. In results of a worldwide survey of children reported by the OECD Observer [9] in 2002, more girls than boys spend at least 30 minutes a day reading for pleasure; magazines and newspapers top the list for both boys and girls, with fiction the second most popular choice for girls and comic books for boys. Libraries stocking manga and comics for children and young adults routinely report......

On Writing

...Ashley Eller December 12, 2011 UCWR110-022 Final Reflective Essay On Writing My favorite author and literary genius, Stephen King, in his memoir On Writing wrote, “Write with the door closed, rewrite with the door open.” This is possibly the best piece of advice I could ever think to give to a struggling student with a paper to write. Your first draft is always for yourself and your own personal reflection. In your second draft, “open up the doors” and write for everyone else who will be reading it. Without this solid piece of advice, I don’t think I could have ever expanded on my writing at all. Over the years, my writing career has hit its peak in junior year, and I have plateaued from there. Since being a UCWR student, I have had the chance to expand my range in my writing skills. From this course, I have learned to expand my writing ability to subjects I would never have broached before, allowing myself to heighten my awareness of the world around me as well as hinder my procrastination. In the beginning of the year, I was very disappointed I would have to take this course. From my previous experience with accelerated English and rhetoric courses, I felt I would be bored and disappointed with the classroom experience. Over the course of the semester, I have learned I was wrong. While in the beginning my engagement level was poor, I was still interested by the current events brought up in class. Some of the biggest topics we discussed (Occupy Wallstreet, Penn State...

...TARCAD: A Template Architecture for Reconfigurable Accelerator Designs Muhammad Shafiq, Miquel Peric` s a Nacho Navarro Eduard Ayguad´ e Computer Sciences Dept. Arquitectura de Computadors Computer Sciences Barcelona Supercomputing Center Universitat Polit` cnica de Catalunya Barcelona Supercomputing Center e Barcelona, Spain Barcelona, Spain Barcelona, Spain {muhammad.shafiq, miquel.pericas} Abstract—In the race towards computational efficiency, accelerators are achieving prominence. Among the different types, accelerators built using reconfigurable fabric, such as FPGAs, have a tremendous potential due to the ability to customize the hardware to the application. However, the lack of a standard design methodology hinders the adoption of such devices and makes difficult the portability and reusability across designs. In addition, generation of highly customized circuits does not integrate nicely with high level synthesis tools. In this work, we introduce TARCAD, a template architecture to design reconfigurable accelerators. TARCAD enables high customization in the data management and compute engines while retaining a programming model based on generic programming principles. The template features generality and scalable performance over a range of FPGAs. We describe the template architecture in detail and show how to implement five important scientific kernels: MxM, Acoustic Wave Equation, FFT, SpMV and Smith Waterman. TARCAD is......

...because that is the past but it was a necessary cause to help end that deadly war. Without this act by the U.S., World War II might not have ended for another year. Usage of Science Hiroshima was based around science. It was the story of the great atomic bomb and all of its radioactive side effects. So yes! Of course this book has to do with science. I found science throughout this book. The radiation poisoning caused by the atomic bomb exploding is just an example of science. This work of non-fiction was built around science. It tells of the not only of the bomb itself but also the side effects of it and how it affected and killed hundreds of thousands of people. This story mostly told the story of how the survivors survived the ordeals of the attack and how they suffered and conquered. Personal Reflections I really liked this story. It was a n outstanding novel and Hersey did a great job in describing the accounts accurately of what happened to these people. It told me a lot about the hardships that these people had to go through because of the attack on Hiroshima. I liked the aft that this story did actually occur and wasn’t just a fictitious story made up by one’s own mind. This story was not only well written but the story behind it was outstanding and credible. John Hersey did an outstanding job writing this novel and I will gladly be persuading others to read about it!...

...drilling rock and then blasting it out with charges.” I agree with Mr. Hemingway. Writing can be easy and enjoyable, or it can be difficult and frustrating. There are times when everything comes together and flows effortlessly and, more often than I would like to admit, there are times when I could pull my hair trying to squeeze out an idea of what to write. Regardless of the headache writing can sometimes be, I am absolutely in love with it. I was not always in love with writing. I was capable of getting assignments like essays, short stories, and poems completed, but not necessarily enjoying the process it took to get there. Everything changed when I took a writing workshop as an elective class in high school. In all honesty, I took the class because I felt as though I was a good enough writer to do well and not have much to worry about. I realized something important in that class, that “good enough” would not be good enough for me anymore. I can remember the exact moment I fell in love with the process of writing. I had an assignment to write a short story, which seemed easy enough. I wrote a quick rough draft about the importance of not drinking and driving. My writing process had always been to write a rough draft that was not very well thought out, to edit a small amount and not much else. I found myself spending more time on that story than I had ever spent on any other piece of writing. I kept editing and changing things until the end result only held a small......

...Chapter 132 - Science and Technology Section SCIENCE AND TECHNOLOGY Science and technology provide people with the knowledge and tools to understand and address many of the challenges. Students must be provided with opportunities to access, understand, and evaluate current information and tools related to science and technology if they are to be ready to live in a 21st century global society. The study of science and technology includes both processes and bodies of knowledge. Scientific processes are the ways scientists investigate and communicate about the natural world. The scientific body of knowledge includes concepts, principles, facts, laws, and theories about the way the world around us works. Technology includes the technological design process and the body of knowledge related to the study of tools and the effect of technology on society. Science and technology merge in the pursuit of knowledge and solutions to problems that require the application of scientific understanding and product design. Solving technological problems demands scientific knowledge while modern technologies make it possible to discover new scientific knowledge. In a world shaped by science and technology, it is important for students to learn how science and technology connect with the demands of society and the knowledge of all content areas. It is equally important that students are provided with learning experiences that integrate tools, knowledge, and processes of science and......

...Iris 05/31/2015 084A Writing in reverse The Principles of Good Writing The average student finds it surprisingly easy to acquire the usual tricks of poor writing. To do a consistently good job, however, one must grasp a few essential principles: 1 Consider the reader. 2 Be concise, clear, and down to earth. 3 Revise Consider the reader Keep your mind between reader and the subject. This is fundamental. Constant and alert consideration of the probable reaction of the reader is a key point to good writing. A logical argument is that if you write good enough, your readers will merit any attention. Consider the reader wherever possible. If the proposed title, for example, means something to you; think further. Similarity, all the way through you must write for readers. Keep your facts and ideas on the different level of emphasis with telltale hints of relative importance or logical sequence. Don’t use long sentences containing many ideas loosely strung together. Do not use and frequently in good writing; because and semicolon appear in good writing. Use transitions in good writing such as moreover, nevertheless and on the other hand. A good sentence begins with the subject or with a phrase that needs emphasis. Don’t hide antecedent or offer wrong antecedent. Consider the reader and use parallel constructions which give the thought away to easily. In every technical paper do not omit a few items that most readers need to know. Use defining symbols:......

The Writings

...II. Kaalaman Ang ating pambansang bayani bilang manggagamot, ay may takdang oras ng konsultasyon sa mga pasyente. Ito ay sa ganap na 8:00 hanggang 10:00 ng umaga sa bayan ng talisay, at pagdating ng 10:00 ng umaga hanggang 12:00 ng tanghali ay sa Dapitan naman siya pupunta para sa konsultasyon. Bilang guro, ayon kay Dr. Maria Valdez sa librong “Jose Rizal and The Writings of His Story”, ang pagtuturo ni Rizal ay mula 1:30 hanggang 4:00 ng hapon. Ngunit ayon kina Vaño ang pagtuturo ni Rizal ay 2:00 hanggang 4:00 ng hapon. Sinabi rin niya sa sulat niya para kay Blumentritt na meron siyang 16 na estudyante. Bilang inventor, ang ating pambansang bayani ay nakalikha ng makina na makakagawa ng laryo (brick) nang mabilisan. Sa katunayan ay nakakagawa ito ng mahigit kumulang 6,000 na laryo sa isang araw. Si Rizal ay nagpadala rin ng sulat kay Blumentritt na kanyang ipinapaalam na nakakita siya ng ibang paraan ng paggawa ng laryo sa Bohemia at kanyang itinanong kung paano ito nagawa sa kaibigan niyang si Blumentritt. Siya rin ang naka inbento ng sulpukan na isang sigarilyong gawa sa kahoy. Bilang mangagamot, may pasyente si Rizal na nag ngangalang “Don Ignacio Tumarong” na nagbayad ng 3,000 Pesos upang mapaayos ang kanyang paningin. Isa pang Ingles ang nagpagamot ng mata kay Rizal na nagbayad ng 500 Pesos. At si Don Florencio Azcarraga mula sa Aklan ay nagpatingin rink ay Rizal. Ang kapalit nito ay isang kargada ng asukal. Bilang negosyante, alam naman natin na si Rizal ay......

...1130 January 2016 A Writing Experience Writing has never been my forte. At best, I survived the earlier years of my school life with average remarks from English teachers who assessed me. However, due to a lack of confidence in my own writing, English classes became incredibly difficult in my final years of high-school. Attempting to obtain better grades, I recall trying to absorb the almost formulaic method of writing my grade 11 and 12 teachers taught, and applied it. Nevertheless, I understood that this method was clearly not improving anything when I received my mark for the English 12 provincial. Being ill prepared for post-secondary writing is not a situation unique to myself. Rather, it is a common phenomenon for student writers of my generation. As mentioned, many student writers of my generation suffer from the same lack of proper writing education as I did when stepping into the world of post-secondary. In fact, recent studies suggest that the writing process being primed into student writers like myself during high-school is too linear, and fails to prepare them for the level of writing post-secondary schools demand for. This is because student writers are being educated to “separate the writing process into discrete stages” (Sommers 135). Moreover, due to the linear nature of current models of the writing process taught in schools, students tend to write in ways that resemble speech and as a result, neglect an important stage in writing: revision. ......

...Understanding Graduate-Level Writing September 14, 2015 Understanding Graduate-Level Writing To understand graduate-level writing, you must look at the characteristics that make this type of writing different from other types of writing. One of these characteristics is to communicate a specific idea or intended message that is precise and elegantly worded, so the reader will not misunderstand (Beins & Beins, 2012, p. 3). Being misunderstood in any type of writing can be one of the biggest factors in how credible you are and if the message you are conveying will have the impact that is intended to make. As a graduate level writer, your technical vocabulary and phrases will play a vital role for difficult or intricate ideas, which should be conveyed in a short and concise manner (Beins & Beins, 2012, para. 9). That being said graduate-level writing generally follows a specific format that can be understood universally (Beins & Beins, 2012, p. 3). This specific and technical format displays one of the differences between the other forms of writing. Other styles of writing that are less formal usually accommodate the content as well as the artistic style of the text (Beins & Beins, 2012, p. 3). Taking the artistic less formal route for writing will allow the reader to understand the message in a less confusing method for virtually any level of understanding. The technical jargon that graduate-level writings entail seem to be one of the important distinctions...

...1.0: Introduction Writing is one of the most crucial aspects in language learning. It is not an easy task as it seems as writing is actually a process; and it is the teachers’ responsibilities to help students becoming good writers. According to Hedge (2005), writing process consists of four stages that are ‘Composing’, ‘Communicating’, ‘Crafting’ and ‘Improving’ (pp. 17). Therefore, this essay presents the main principles that underlie in activities that assist learners at these different stages in the writing process which is designed by Tricia Hedge in her book, ‘Writing’ (2005). This paper will start with a discussion about the first stage of writing that is ‘Composing’, and continue with another stage which is ‘Communicating’. ‘Crafting’ will be explained next, and finally, the last stage which is ‘Improving’ will be addressed. Additionally, an example of activity will be illustrated in each section. 2.0: Composing Composing is a stage that ‘takes a writer from pre-writing to polishing a final draft for a specific purpose and a particular audience’ (pp. 81). Hedge believes that good writing is often recursive, and not linear where various operations take place simultaneously throughout writing process. There are three main activities in this stage; pre-writing, drafting and redrafting, and editing. In pre-writing, the focus will be mainly on planning the outlines and exploring possible content. The learners will be aided to identify the purpose and the......
