SAMPLE LAB REPORT. The theory of optimal foraging and its relation to central foraging was examined by using the beaver as a model. Beaver food choice was examined by noting the species of woody vegetation, status (chewed vs. not-chewed), distance from the water, and circumference of trees near a beaver pond in North Carolina.

Each hair has, in addition to a mechanoreceptor, five distinct cells – alcohol, oil, water, salt, and sugar – that determine its acceptance or rejection of the food (Dethier, ). 10 Sample Lab Reports. A laboratory report, also lab report, is a piece of document that describes and analyzes laboratory experiments to explore scientific concepts. A laboratory report is designed to enable researchers to conduct the research process and the rest of the steps needed to be able to come up with the evaluation and distribution of the results.

Here are two examples of a lab report. The first is what not to do, the second is a cleaned-up and much improved version of the same report. Ethan Gallogly. What NOT to do Student Chemistry 1. As described in the lab manual:. Record the barometric pressure, sample of a lab report. Measure about 10 g of ice using the chemical balance and place it into a mL beaker. Heat over a flame until half of the ice has melted.

Remove from heat and measure the temperature as accurately as possible using your laboritory thermometer. Repeat with a Be sure to record your unknown number. Bring the liquid to a boil over a flame. After the liquid has been boiling for approximately minutes, measure the temperature of the boiling liquid. Repeat with a 10 g sample of your unknown. Record all data in your lab notebook and clean up.

The pressure in the room was Correcting for our water results this made our measurements — Other errors include: possible math errors in our calculations and human error. Overall the lab was really good and we learned quite a lot of stuff. I especially liked the part where the blabber gas exploded when heated scaring my partner I think that may be why she broke the thermometer. For references we used our textbook, lab manual, and the Chemical Handbook found sample of a lab report shelf 2 of the library behind the reference desk.

What to do:. One of the primary methods used to characterize a new compound is the physical determination of its normal melting and boiling points. In this experiment we will first calibrate our thermometers using ice and water, whose normal melting and boiling points are well characterized as 0. Following this, we will measure the normal melting and boiling points of an unknown compound. We will use this data to determine the identity of our unknown from a list of possible unknown samples and physical data from the Chemical Handbook [2], sample of a lab report.

Experimental Procedure. This was followed by a similar measurement of our solid unknown. This was followed by a similar measurement using our unknown compound. To get the best results possible, the procedure in the manual was modified by repeating each trial three times. The Barometric pressure in the lab was measured to be Melting Pt.

Boiling Pt. Unknown 7. Standard deviation s :. A new thermometer was obtained from the stockroom and used for all other data, sample of a lab report. Observations: The unknown was yellowish-orange in color and had a fruity smell.

These differences were used to calibrate the average data for the unknown. Thus the corrected values for the unknown boiling and melting points are given in Table 2. Corrected value. These values were used to identify our unknown.

Table Three below lists possible unknowns and the melting and boiling points for these compounds found in the Chemical Handbook. Melting Point. Boiling Point. Freezer Gel. Sample of a lab report Putty. Farsel Juice. Although our measured melting and boiling points differed from the theoretical data by a few percent, this difference was very small leading us to believe that our results were quite good. While there is sample of a lab report room for error in our results due to the change in boiling and melting points as a function of atmospheric pressure this difference should be very small.

Other factors such as contaminates in the water sample of a lab report may have affected the results, but again every effort to minimalize such effects was made by using only deionized water. Finally we did encounter some problems with our thermometer in the first trial, but this was fixed by replacing it at the stockroom. In this lab we determined the identity of our unknown to be Farsel Juice using normal melting and boiling points.

Chemistry Lab Report in Word. A lab report is a record of the activities, processes, and observation during and after an experiment. You may check out our Sample Lab Reports for more details. It includes some of the following parts: Introduction – like any other write-up, it is necessary to write an introduction. Lab report structure. Lab reports can vary in length and format. These range from a form to fill in and submit before leaving the lab, to a formal written report. However, they all usually follow a similar . SAMPLE LAB REPORT. The theory of optimal foraging and its relation to central foraging was examined by using the beaver as a model. Beaver food choice was examined by noting the species of woody vegetation, status (chewed vs. not-chewed), distance from the water, and circumference of trees near a beaver pond in North Carolina.
