Figure 2 displays that there was no pattern between the molars of the three animals. Discuss reasons why the data might be wrong. A Gram stain was performed which verified Gram-positive cocci. Gram-negative rod shaped bacteria were identified using the microscope. The first titration was the lightest in color of the three titrations and the second titration was the darkest. The methods that were previously studied and practiced in the Microbiology laboratory class were applied in order to identity two unknown bacterium.

The streak plate was then incubated at 37 degrees Celsius for 48 hours. The coyote and human molar cusps were very similar in molars one and two. From previous biochemical tests done in the semester, Pseudomonas aeruginosa was already suspected because of the green pigment of the original streak plate. Relative tooth width displays the tooth width relative to the length of the jaw. Explain what the other conclusions are. The data section must be organized and consistent with any format suggested in the laboratory manual. A sample was taken from the isolated nutrient agar and a gram stain was done as directed by the lab manual 1.

Make sure to include all of the materials used. After determining the Gram-negative reaction, specific tests were performed. Usually the last sentence is a statement of the hypothesis that was tested. A standard lab write up includes the following sections: I. Use Excel to display the equation of the best fit line through your data.

What will be learned from doing this experiment? Gram-positive bacteria did not grow. That is, you will perform a test of how two variables might be related. For students serious about pursuing a career in science, a lab report is a stepping-stone for submitting work for review. In the medical field bacteria and infections of different kinds are the core of the practice. In this lab, you design an experiment to test a hypothesis about the geometry of circles. It then rolled on the floor until it came to a stop. This can be a single paragraph or one or more pages.

As well as using the quadrant method to further isolate the colonies, a sample was taken from the best colony on the original streak and gram stained. How does motion relate to where the organism lives? You do not need to write out the procedure unless explicitly instructed to do so. They have all the organelles necessary for a variety of functions such as digestion, excretion, reproduction, respiration, and movement. This was isolated and a Gram stain was performed. Alternatively, materials can be included as part of the procedure.

Sample Descriptive Lab Report

Conclusion In this lab I learned about the structure and function of the smallest eukaryotic organisms, the unicellular protists. Pseudomonas aeruginosa is a gram negative rod shaped bacteria that was first discovered in 1882 by a pharmacists named Carle Gessard 2. Article Summary To do a lab write up, determine the problem and your hypothesis, make a list of the necessary materials, and explain the procedure of the lab. If all the data lie exactly on the fitted line, R squared is equal to 1. If the data are randomly scattered, R squared is zero. There are two key reasons.

Gram positive did not grow. Despite differences in locomotion and the varying plant-like and animal-like organelles, all protists share key characteristics and functions that allow them to feed, grow, and reproduce--processes essential for survival and common to complex organisms. Conclusion: This experiment showed that when a soccer ball was rolled off the surface of a table at 4 feet high it dropped to the ground. The results are also displayed in a flowchart. Past tense can be used when describing specific methods and observations, or citing research or experiments done in the past. It was determined that it was a Gram negative rod.

Make sure you record what you do as you do it, so that the procedure section of your report accurately and completely reflects what you did. If they represent other schools or institutions, credit this too. This result supports the theory that gravity causes objects to fall toward the center of the Earth when they are dropped. What Is a Real Hypothesis? On the top jaw, the deer had zero incisor and canine teeth but have three of both the premolars and molars. Lab reports are time-consuming for both students and graders, so why are they so important? This takes you through a step by step procedure of the lab. The next test performed was a Nitrate Test which gave a positive result.

These toxins have proteins that activate antibodies which causes resistance. On the bottom jaw, the deer had three incisors, one canine, three premolars, and three molars. The intercept is essentially zero: -0. Examples of quantitative results are measurements in units like centimeters, weight in grams, speed in kilometers, along with density, volume, temperature, and mass. The gram stain procedure was performed as directed in the lab manual 1. I also learned to identify and classify different types of protists.
