How to write a purpose statement for chemistry lab

how to write a purpose statement for chemistry lab

Statement by Russian Student (01/2003)
The Chemistry Student admitted to Florida State University, Auburn University


I am seriously interested in Chemistry from the time when I was a schoolboy. Not satisfied with standard school program, in the last 2 years of high school I studied in Moscow Chemical High School which had a strong science and mathematics training. This greatly developed my skills and helped me to win three School Chemistry Olympiads.

After graduation school I entered the Mendeleev University of Chemical Technology – one of the best educational institutions for Chemistry in Russia. By March 2003, I will complete 5 1/2 years of undergraduate studies and receive a University Diploma. In our Physical Chemistry Department students are required not only to take undergraduate courses, including chemical engineering, but also to carry out research in one of the major research centers in Moscow or at the University.

I intend to continue my research work in chemistry. The main goal of my future education is to gain valuable research experience and deepen my knowledge of chemistry. I have chosen Florida State University because it provides excellent opportunities to pursue research in various areas of chemistry.

Since 1999 I have been doing research work at the Division of Chemistry and Technology of Crystals of the University. My research for the most part is related to areas of Physical Chemistry such as Solid State Chemistry, Crystal Growth, Surface Chemistry and others. My first project was synthesis and determination of thermometric parameters of luminophors based on Zinc Sulfide doped with Bismuth. I synthesized and analyzed 19 luminophors with different additives such as Eu, CdS, LiCl and others. As a result of this work, I presented a paper entitled “Non-traditional application of luminophors” at the General Chemistry Institute of the Russian Academy of Sciences student conference in 2001.

In Fall 2001, I switched to research in the field of crystal growth. My second project concerned the single-crystal growth of Calcium and Barium Tungstates (CaWO4, BaWO4). This work I accomplished at the General Physics Institute of the Russian Academy of Sciences. I grew these crystals by flux growth (Czochralski technique). Such single-crystals are important as nonlinear solid-state components for lasers of stimulated scattering.

In addition, I have done work on deposition of thin films. This interesting laboratory practice was lasting during the one of my favorite elective courses “Technology of Heterostructures”. The subject of my research was physical and chemical thin film deposition of Lead Tellurium (PbTe) and Gallium Arsenide (GaAs) from gas phase, thus I have gained practical experience in deposition of thin films of A3B5 and A2B6 heterostructures in vacuum on silicon substrate. Such films are used in the electronic industry as semiconductor layers.

In Spring 2002, I began a project that set the basis for my graduation paper. This research deals with the powder and nanoparticles of Aluminium Oxide (Al2O3) which I analyze by adsorbtion measurements and Monte Carlo simulation. I determine the pore size distribution of the materials based on the compound that is essential for creation of non-organic filters.

Moreover, during the 2001/2002 academic year, I had an important experience as an instructor for freshmen at the General and Inorganic Chemistry Laboratory. Also, I often help foreign students to learn the Russian language. I should say that I enjoy teaching.

During my study I dealt with different research projects and I have various research interests, but the major area in which I would like to specialize, if I will be accepted at your graduate school, is Physical or Theoretical Chemistry. I hope that my research work (including research program) will be beneficial for the University and myself. I am very interested in doing research work at Florida State University.

During an experiment you may collect a lot of information, or data. But that data is not very useful unless it is organized. The purpose of a lab report is to organize and communicate what you did in your experiment. A good lab report explains exactly what you have done. It can be used to repeat the experiment or to test other hypotheses in new experiments.

(Name)__________________ (Date)______________

Title: ______(the name of the lab or experiment)


The purpose or problem states the reason(s) why you are doing the experiment. Write down exactly the problem that will be investigated or experimented. Purposes can be stated as a question.


In a few words tell what you already know or have found about the problem that will let you make an educated guess. This is your background information from the text, teacher, or other sources. It gives the reader an understanding of underlying principles and content information of the laboratory.


What do you expect to find?

The hypothesis does not have to guess the correct outcome, but the experiment must be set up to test the hypothesis.

This is a list of all equipment and chemicals used to do the experiment. Please include quantities (amounts).


The procedure tells exactly what you did. Make statements in the past tense. Be specific. The procedure you use affects the results. So, it is important to be accurate in explaining what you did. The procedure is written in paragraph form.

Observations and Data:

The observations tell exactly what happened when you did the lab. An observation is measurable information that comes to you through your senses. Results include experimental (raw) data in the form of well-labeled tables, graphs, drawings and other observations. Place your observations and data in this section without discussion or comment. This is where you include any calculations made during the experiment. Answer any questions here.


Conclusions explain your observations and describe how your data relates to the problem.

The bar and marker shared the same relationship with the table and the frame. The more the frame moved, the greater the amplitude on the seismograph.

In order to further investigate this problem, next time I would try the experiment on a different surface and would add additional movements of varying forces for further readings on the seismograph.

(Name)_____ (Date) _____







Observations and Data:


This lab (experiment) investigated __________. In order to study the problem we ___________. My results showed ____________, thus proving my hypothesis was ____________. I believe the results are (accurate/inaccurate) because ____________. In order to further investigate this problem, next time I would _____________.

  • Do draw a picture of the experiment, if appropriate.
  • Dont say that the purpose was accomplished and then say nothing substantially more. You must include data from the lab results to demonstrate that the purpose was accomplished.
It was already listed in the data (chart, table, etc.). You are to discuss and draw conclusions from the data.
  • Dont forget to break up your ideas with more than one paragraph, if necessary. (This is referred to as an essay!)
  • Co-op
  • Cheryl also suggests that the basic format suggested by Dr. Wile: Title, Date, Observations/Data, and Conclusion/Summary is adequate for 7th, 8th and 9th graders and the full format for documentation that she suggests above is optional.

    Here's a format for a lab report you can use if you aren't sure what to write or need an explanation of what to include in the different parts of the report.

    A lab report is how you explain what you did in ​your experiment, what you learned, and what the results meant. Here is a standard format. If you prefer, you can print and fill in the science lab report template or download the pdf version of the template.

    Lab Report Essentials

    1. Title Page
      Not all lab reports have title pages, but if your instructor wants one, it would be a single page that states:
      • The title of the experiment.
      • Your name and the names of any lab partners.
      • Your instructor's name.
      • The date the lab was performed or the date the report was submitted.
    2. Title
      The title says what you did. It should be brief (aim for ten words or less) and describe the main point of the experiment or investigation. An example of a title would be: "Effects of Ultraviolet Light on Borax Crystal Growth Rate".
    Sometimes an introduction may contain background information, briefly summarize how the experiment was performed, state the findings of the experiment, and list the conclusions of the investigation. Even if you don't write a whole introduction, you need to state the purpose of the experiment, or why you did it. This would be where you state your hypothesis.
    1. Materials
      List everything needed to complete your experiment.
    2. Methods
      Describe the steps you completed during your investigation. This is your procedure. Be sufficiently detailed that anyone could read this section and duplicate your experiment. Write it as if you were giving direction for someone else to do the lab. It may be helpful to provide a Figure to diagram your experimental setup.
    1. Data
      Numerical data obtained from your procedure usually is presented as a table. Data encompasses what you recorded when you conducted the experiment. It's just the facts, not any interpretation of what they mean.
    2. Results
      Describe in words what the data means.
    This is also where you would discuss any mistakes you might have made while conducting the investigation. You may wish to describe ways the study might have been improved.
  • Conclusions
    Most of the time the conclusion is a single paragraph that sums up what happened in the experiment, whether your hypothesis was accepted or rejected, and what this means.
  • Figures & Graphs
    Graphs and figures must both be labeled with a descriptive title. Label the axes on a graph, being sure to include units of measurement. The independent variable is on the X-axis. The dependent variable (the one you are measuring) is on the Y-axis. Be sure to refer to figures and graphs in the text of your report. The first figure is Figure 1, the second figure is Figure 2, etc.
    1. References
      If your research was based on someone else's work or if you cited facts that require documentation, then you should list these references.
