Jade Boyd 01/25/18 Ch. 1 Hypothesis Formation & Evaluation Bio 111 Lab

1. The title of the sample lab report is so long to clearly represent what the lab report is about and the purpose of the experiment. It doesn’t need to be cute and catchy, it needs to be simple and concise and include the hypothesis in some way. 2. The abstract gives a small amount of background information on aspects of the experiment and uses some vocabulary necessary for the experiment. In this case it explains that plants require light for photosynthesis and what phototrophic means. The abstract also explains why the experiment was conducted. Lastly, the abstract briefly explains the results of the experiment which are further explained in the results section of the lab report. Overall the abstract serves as a short summary of the entire report. 3. The introduction includes references to stop from plagiarism and give credit where credit is due. The introduction addresses the question that is being asked in this paper by explaining what information is needed to even wonder that question in the first place. You would not ask ‘what is the effect of short light exposure to the growth of seedlings’ if you did not know to what depth plants are dependent on light in the first place. Scientific facts are needed for this experiment and report to be understood and the introduction provides this. The introduction also mentions the focus of the experiment. The authors do explain the results predicted by the hypothesis in this introduction. In the exercise, the hypothesis was stated as “Plants must sense that there is a sufficient amount of light available to them before they change their growth pattern. Therefore, there is a minimum amount of time of light exposure required before a plant will show a response.” In the lab report, the hypothesis was stated as “the hypothesis of this experiment is that there is a minimum time period of light exposure required for a plant to show a phototropic response.” The author changed the way the hypothesis was stated in the lab report because the extra background information that they had in their exercise hypothesis had already been stated in the introduction and would have been redundant to repeat. 4. While the methods section doesn’t provide a bulleted list of what equipment was used in the experiment, it does go through the processes used and mentions what equipment was used in each step. The methods section is very similar to a lab manual in explaining how the experiment was conducted and explaining each step. References are cited in this section. The methods section is written chronologically and without any fluff or excess but also without becoming too simplified, this is to ensure other scientists understand exactly how the procedure was conducted so they can repeat the experiment again if they wish to. The independent variable is the amount of time the seedlings were exposed to

light and the dependent variable is the angle of growth of the seedlings after light exposure. 5. Highlighted and labeled. 6. The discussion does repeat information stated previously in the report because the discussion is similar to the conclusion of an essay, it restates important information and ties together the background information, the hypothesis, the results of the experiment, and what these results implicate for the real world. The reference mentioned in the discussion is important because this information is vital to the experiment but it was not discovered by the author of this lab report and must be credited to where the author found this. The results of this experiment support the original hypothesis. 7. All of the references are cited somewhere in the lab report....
