How to write a chemistry lab report

Components of the chemistry lab report 


Most of the students prefer interactive studying to tedious theory. We understand the theoretical aspect better when we observe them in practice. The experimental activity is a necessity for improvement of the learning process, especially if it concerns sciences as physics, chemistry, biology. A lab activity has to be carried out in the workroom conditions in the form of test. The practical experience enables to explain the material more thoroughly. Practice proves that practical lessons significantly increase the interest of students in the studying process. The only difficulty the young people may face is the reporting of their results. 

Although experimentally everything has been proved, it is sometimes difficult to draw all conclusions on paper in the correct form. But as the teacher evaluates the written form of the experiment's findings, you have to learn how to write it. You can get acquainted with the examples to understand their principles. 

Structural elements of the laboratory test paper 

Abstract 


Usually abstract includes one or two paragraphs where you make a detailed summary of the whole paper. As a rule, it is written after the completion of a work on the main part. It includes the next elements: 

- characteristic of the main subject; 

- problem; 

- object; 

- purpose of work; 

- methods; 

- results; 

- discussion. 

The abstract allows to define the reader the main contents of the lab and gives a compact form of your work. 

Introduction 


The introduction is such kind of presentation of your work. It is intended to provide the core information about your practical model of chemical processes. The important elements to include in this part are: 

- statement for the general research subject; 

- theoretical background data; 

- key terms; 

- general methods of the experiment; 

- formulation of a central question; 

- description of the work course, a hypothesis, results; 

- suggestions concerning certain observations. 

Experimental (Materials and Methods) 


The student has to describe all the equipment of the process. It must be clear which subjects did you use and with which purpose. Explain in detail every step so that any other person can understand and repeat the experimental procedure by your descriptions. Here you can find the tips about its contents: 

- define the general type of a scientific procedure for investigating the problem; 

- describe all the item of laboratory equipment you have used; 

- describe all your actions within the experiment; 

- provide tables, schemes, mathematical formulas, statistics of your observation. 

Results 


The experiment performer has to present systematized material. All the proceeds must be explained thoroughly. The repeating of your actions algorithm must bring the same result. In this way can be proved the validity of the conclusions drawn by the author. The results are one of the most responsible parts because here you have to prove a working hypothesis and sum up what you have done. 

If necessary, you can support the results with illustrations, tables, lists, drawings which present original material or proofs in the reduced form. Outcomes of the research have to be stated briefly but be informative enough to evaluate the drawn conclusions. 

Discussion 


It is the part where you have highlight the importance of your conclusions. The necessary things to do here are: 

- compile your findings; 

- describe the cause-effect relations, regularity of your results; 

- explain if the received results met your expectations and assumptions; 

- point out the possible contradictions and exceptions if any; 

- give your suggestions for further researches; 

- presume the implementation of your results in other situations; 

- present the practical use of your findings. 

Conclusion 


The conclusion contains a short total of the research. Here the student presents the central thoughts of his report. To avoid any iteration of the already stated information in other parts, it is advisable to change the wording. The received results should correspond with the purpose designated at the beginning of work. 

In conclusion, as a rule, the student makes a short review of all the written above and accentuates the weight of his work.
