...Why do we keep a lab notebook? In the ‘real world’, you will be expected to record what you do and how you do it, with the data clearly identifiable. There are 2 reasons for this: • Any scientific experiment is only considered valid if it can be repeated by someone else using your notebook. • If you develop a new product or process, your notebook becomes a legal document that can be scrutinized in a court of law, especially in cases of patent infringement. In order to meet these requirements, certain conditions must be met: • Notebooks shall have bound pages, loose-leaf and spiral bound are not acceptable. • All pages must be numbered prior to use. This will show if any pages have been removed that contained data that might compromise interpretation of your conclusions. • All data shall be entered chronologically. Do not leave empty pages to insert information later. If you finish with a large expanse of blank page, put a line through it to show that it will not be used. • All notes are to be made in indelible pen – pencil will be penalized. If you make a mistake, just draw a single line through it, not a childish scribble to hide all traces! • All data will be recorded in your lab notebook at the moment it is generated. No notes shall be written on scraps of paper or memorized for later. Other notes about the lab notebook: All pre-lab and experimental work is hand-written in your lab notebook. Make...

...C8057 (Research Methods in Psychology): Writing Laboratory Reports Writing Lab Reports & APA Format Structure and Content of a Laboratory Report This following provides a brief overview of the structure and content of various elements in a laboratory report, based on APA guidelines. The APA publication manual can be referred to for more detail. The purpose of a lab report is to communicate research in a clear, systematic and standardised way. Primarily, a lab report should communicate the following things: → Why did I bother? Why did I do this experiment and why is it an interesting contribution to science? → How did I do it? How did I carry out this research (this should be detailed enough so that the experiment could be replicated precisely)? → What did I find? What were the results of your study? → So What? What do your findings mean in terms of your hypotheses and what theoretical contribution do they make? IMPORTANT! The advice that we give you in this handout is not inflexible, it is a guide! For example, when we say that the title should be fewer than 15 words, the world will not end if your title is 16 words. So, please use your common sense. In case you don’t have any, the snail of sense will appear to give you some advice. Format There are several sections to a lab report: → Title → Abstract → Introduction → Method o o o o o → Results → Discussion → References → Appendix (Optional) Title Your title should ideally be fewer than 15 words. A good title alerts the reader...

...Name: Gertrude Edwards Date: 12/1/2014 Instructor’s Name: Staci Lynn Assignment: SCI203 Phase 2 Lab Report TITLE: Speciation • Purpose o The purpose of this lab is to evaluate what would happen if a species within a population were suddenly split into 2 groups. • Introduction o If a population is divided indefinitely by a barrier members of the divided population will not have the opportunity to breed with each other, over years, the biotic and abiotic conditions on either side of the barrier will vary from one another. (M.U.S.E). • Hypothesis/Predicted Outcome o Based on what I’ve learned I expect that species will undergo changes if they were split into 2 different groups, some would adapt and some wouldn’t. • Methods o The methods I used in this lab came from M.U.S.E. The initial separation would consist of some species from the mainland reaching the isolated Island, then after that the isolated population would begin to diverge because of the genetic drift and natural selection, then after that overtime divergence may eventually become sufficient to cause reproduction isolation. (M.U.S.E). • Results/Outcome o As a result, Natural selection will cause different selective and adaptive pressures to occur between the two divided populations and they will evolve forever. Over time this will result in speciation which is the creation of two new species. (M.U.S.E). • Discussion/Analysis ...

...Lab 1: Introduction Metric System Prefixes (to put in front of basic units): k = kilo = 1000 x c = centi = 1/100 of (which is 10-2 of) m = milli = 1/1000 of (which is 10-3 of) ( = micro = 1/1,000,000 of (which is 10-6 of) n = nano = 1/1,000,000,000 of (which is 10-9 of) (d = deci = 1/10 of ) [pic] (Note: The way to read the numbers above, for example, is: There are 1000 nm in one (m. There are 1000 (m in one mm.. etc.) To convert from one metric unit to a different metric unit (a different prefix): 1. First, decide how many places to move the decimal point (the number of 0’s in the chart above indicates the number of places to move the decimal point). 2. Next you need to decide whether to move the decimal point left or right. To decide this, think about which is the smaller unit. (The smaller the unit is, the more of them you need to get the same amount. e.g. pennies vs. dollars) NOTE: Here is another way to write the conversions, using distance (the meter is the basic unit for distance) as an example: 0.001 km = 1 m = 10 dm = 100 cm = 1000 mm = 1,000,000 (m = 1,000,000,000 nm The “staircase” method: One more way to remember about sliding decimal points when converting between prefixes in the metric system! [pic] Move the decimal point 3 places for every step you move on the “staircase”, and in the same direction traveled on the staircase (left vs. right). Unfortunately, you can see that the “c” prefix...

...Lab report As part of my module Nip1002 I was required to perform a set of observational skills which included; pulse, blood pressure, respirations, hand washing and urinalysis and then compare them to previous results. In this lab report I am going to discuss blood pressure in detail. Procedure * Explain the procedure to the patient and gain consent * Wash hands thoroughly following the hand wash technique to prevent the transfer of bacteria * Clean equipment e.g. blood pressure cuff and stethoscope using antibacterial wipes * Ensure the patient is comfortable and has been resting for 10 minutes * Remove tight clothing and support the arm at heart level, overestimation or underestimation can occur if it is not at the appropriate level * Ensure you have the correct cuff size for the patient or this could give an inaccurate reading * Locate the brachial artery and apply the cuff * Estimate the systolic pressure by using the radial pulse and inflate the cuff until the pulse cannot be felt. This is important to provide an estimation and avoids error in reading. * To take the patient’s blood pressure use a stethoscope and place on the brachial artery pulse and inflate 20-30 mmHg higher than the estimated systolic pulse * Immediately release the pressure using the thumb valve at approximately 2mmHg per second. If it is deflated too rapidly you may not hear the sounds accurately * The systolic pressure is the level when clear tapping sounds...

...Apparatus, materials and methods "As the name implies, the materials and methods used in the experiments should be reported in this section. The difficulty in writing this section is to provide enough detail for the reader to understand the experiment without overwhelming him or her. When procedures from a lab book or another report are followed exactly, simply cite the work, noting that details can be found in that particular source. However, it is still necessary to describe special pieces of equipment and the general theory of the assays used. This can be usually be done in a short paragraph, possibly along with a drawing of the experiment apparatus. Generally, this section attempts to answer the following questions: 1, What materials were used? 2. How were they used? 3. Where and when was the work done? (This question is most important in field studies.)" Observations and/or results with discussion Results "The results section should summarize the data from the experiments without discussing their implications. The data should be organized into tables, figures, graphs, photographs, and so on. But data included in a table should not be duplicated in a figure or graph. All figures and tables should have descriptive titles and should include a legend explaining any symbols, abbreviations, or special methods used. Figures and tables should be numbered separately and should be referred to in the text by number, for example: -Figure 1 shows that the activity decreased...

...Lab Report Introduction: Natural selection relies upon the assumption that all organisms produce more offspring than can survive in an environment demonstration limited resources. The heritable traits that are best suited for a particular environment should be passed on at a greater frequency then those less adaptive traits. Natural selection is unique in that it leads to adaptive change, and these changes are likely to lead to increased survival and reproductive success. To sum up, natural selection is that organisms can survive only because they can suit to the changed environment which means those organisms also need to change with the environment all the time. Hypothesis: during the experiment, the forks out of all the “predators” should survive, and the peas out of all those “preys” will be survived. Material and Metnods: We will use 4 kind of beans (preys items) which are fava beans, white beans, red beans and peas. And we also have 4 mouthparts (predators) which are knives, forks, spoons and foreceps. First, we get 100 ml for each prey and spread them on the ground. And the students will be divided into 4 groups with those 4 different predators. Each group of predators include 6 student. And all of the predators will have a cup which will serve as the stomach into which the prey will be placed. We also have a timer and a security that will make sure the process is fair. Here we begin the game. The predators will be gathered, they will be instructed not to...
