Example of a well-written lab report Return to Example of a single-spaced to conserve paper; yours should be double-spaced to leave room for comments Ontogenetic Color Change and Mating Cues in Largus californicus Hemiptera: Largidae Carey Booth Box 123 Biology 102 2 February 1995 Lab instructor: Ned Knight Lab day: Friday Abstract Ontogenetic color change at sexual maturation can be useful in identifying an appropriate mate for some organisms. The first page of a lab report should be a title page with the title of the report, your name, the date, the course e. These bugs do not fly and are easily handled and painted without significantly disrupting their normal behavior. Since any activity requires energy, metabolic rate was probably exaggerated in the mammals. Audience Write the report as if you were writing to other students who are taking a similar course but have not done this experiment. Based on background knowledge regarding beta fish, I believe that the male beta fish will be the first out of the two specimens to display any aggressive behavior. In order to test for similarities in various blood proteins, the Nutall Precipitation process was used.
In order to corroborate our findings, we suggest that this study be repeated by others. Specify the objectives of the experiment, and make your hypotheses clear. Experiment, Laboratory, Logic 1036 Words 4 Pages and B3were placed on the tube rack at about 22°C ; Tube A4 and B4 were placed into an ice bath at 0°C. Figure 1: Mean male mount time sec with 95% confidence intervals under three experimental conditions. The test was to determine the point of subjective equality by having subjects adjust line segments to equal the length of a standard line. Please keep that in mind when using the free sample personal lab report templates.
Thus, they will react to test reagents also called indicators differently. The theory of optimal foraging and its relation to central foraging was examined by using the beaver as a model. This lab gave us the opportunity to observe how a specific mammal selects foods that maximize energy gains in accordance with the optimal foraging theory. By the same token, an organism that expends no energy to maintain a constant body temperature would have a much lower metabolic rate. .
Other experiments are necessary to determine the nature of the communication between adults and between adults and nymphs. Acid phosphatase is shown to have an optimum pH ranging anywhere from 4. Begin the discussion by interpreting your specific results and end it more broadly by placing your results in context. The Quarterly Review of Biology. . They form an essential part of your grade and can be included in lab notebooks or submitted independently.
. Such actions are plagiarism, even though the statement may not be word-for-word the same as in the original. You still need to organize your ideas carefully and express them coherently. To order our assistance, please fill in and submit the order form. For example, the protein solution albumin. Hypotonic Has a lower concentration. I will vary the substrate.
The report is divided into several well-defined sections. This consists of the male orienting towards the female when he is approximately 1 cm away, rapidly waving his antennae, leaping onto the female's back, and agitatedly grabbing the female with his legs. The aim of this document is to provide a general guideline on writing a lab report. These were determined using the Debye-Sherrer powder camera method of X-ray diffraction. Likewise, your raw data can be placed in an appendix.
This reiterates the profound and necessary ability to regulate pH levels throughout the different systems of the body. In holometabolous insects, such as Lepidoptera, maturation is associated with dramatic morphological changes, therefore distinguishing between larvae and adults for mating attempts is not difficult. You have already performed the experiment — why do the boring part? Lab report templates have been created to make the work of lab techs easy. Figure 2 mainly shows that lactate enzyme has a very small window of for optimal pH, centering around 5 and decreasing drastically at a pH of 6. Discussion Basal metabolic rate is the minimal wakeful energy expenditure Fox, 1984.
. In addition to the title, each table and figure should have a legend 1 to 3 sentences which explains what is being presented. Optimal foraging and community structure: implications for a guild of generalist grassland herbivores. If you were to do the experiment again, what if anything, would you do differently? For line orientation, overestimation was greatest when the lines were horizontal. This finding is similar to Belovskyís finding of an inverse relationship between distance from the water and percentage of plants cut. This handout was written by E. .
Methods and Materials: This section of your lab report involves producing a written description of the materials used and the methods involved in performing your experiment. At the end of the day, if used correctly, the template can help you create a suitable project that will be useful for the lab assessment as well as other requirements there may be. To answer this three separate classes had the opportunity to create their own bio-cylinders, place a specified number of organisms, seal it, and observe the cylinder for however long the organisms were able to survive. The introduction is more narrowly focussed than the abstract. Be specific; for example, the instruments could not measure precisely, the sample was not pure or was contaminated, or calculated values did not take account of friction. The report must be logical throughout and rationales must be explained well. Enzymes consist of various types of proteins that work to drive the chemical reaction required for a specific action or nutrient.
Outside the lab, though, you should not discuss your writing of the report with anyone else, other than a tutor at the Writing Center. When there is an increase in agglutination between the animal and human blood, it signifies that the two species' blood are more similar, thus showing a closer relationship. The result that chewed trees were closer to the water accounts for the time and energy spent gathering and hauling. The circumference, the species, status chewed or not- chewed , and distance from the water were recorded for each tree in the study area. In diurnal Lepidoptera, adult color pattern plays an important role in the initial phase of mating behavior Graham et al. The Endocrine systems mechanism of communication is sending messages from the cells of the endocrine and nervous system to the cells in other systems by releasing hormones.
