INTRODUCTION TO CHEMISTRY - CHEM 106

Chemistry for Allied Health II

LABORATORY REPORT FORMAT

Spring 2011,

Title Page

a. experiment title

b. student names

c. date submitted

 

Objective

A one-or-two sentence statement of the objectives, goals or purposes of the experiment.

 

Procedure

It is necessary only to provide an explicit reference to the source(s) of the procedure; it is not necessary to include the complete procedure. For example, Colligative Properties of Solutions, Chemistry 116 Laboratory Manual 1999.

 

Experimental Details

This section should describe what was actually done. It is a succinct exposition of the laboratory notebook, describing procedures, techniques, instrumentation, special precautions, and so on. It should be sufficiently detailed that other experienced researchers would be able to repeat the work and obtain comparable results.

 

If the experiment is performed without modification using a published procedure, it is necessary only to provide an explicit reference to the source(s) of the procedure. For example, Colligative Properties of Solutions, Chemistry 106 Laboratory Manual.

 


Calculations

Sample calculations should be shown for each type of calculation requested in the experiment. Calculations can sometimes be organized into a table.

 

Results

In this section, relevant data, observations, and findings are summarized. Tabulation of data, equations, charts, and figures can be used effectively to present results clearly and concisely. Schemes to show reaction sequences may be used here or elsewhere in the report.

 

Discussion

The crux of the report is the analysis and interpretation of the results. What do the results mean? How do they relate to the objectives of the project? To what extent have they resolved the problem? This is the place to prove, in your own words, that you understand the concepts

included in the laboratory experiment. This section should be written assuming the reader is not familiar with the laboratory experiment.

 

Conclusions & Summary

A separate section outlining the main conclusions of the project is appropriate if conclusions have not already been stated in the "Discussion" section. A lengthy report, or one in which the findings are complex, usually benefits from a paragraph summarizing the main features of the report - the objectives, the findings, and the conclusions.

 


COMMENTS ON WORKING IN GROUPS

Why work in a group?

Throughout the semester your lab work will be completed in a group. Why do we put so much emphasis on group work? Our reasons are really twofold. First, both you and the other members of your lab. group will understand the labs better. Educational research has shown that cooperative group work is an effective means for teaching/learning science (and almost any other subject) and can help increase your understanding of the material. Every time you have to explain something to a group mate, the better you will understand the concept. Second, for those times when you find yourself clueless (it happens to all of us from time to time), group work gives you the opportunity to have someone besides your Graduate Instructor or professor explain the concept to you. Sometimes your group mates will have a common experience that will make a great memory association or analogy for you that is unknown to the staff. This means there are benefits for all group members, if the group is functioning properly.

 

 

Building a working group

Although most humans are by nature social creatures, cooperative group work is not something that comes without effort. Such group activities require that a sense of trust be built between members, as well as a feeling of shared responsibility. This means a responsibility to carry your own weight in the group, as well as a responsibility to all of the other members of the group. In such a case, no one group member gets frustrated and rushes on ahead of the

group, and the group NEVER leaves any of its members behind. This may not always be easy. What do you do when you have someone in your group that you don't like? Or who doesn't like you? How do you deal with group members who refuse to help you out when you are confused?

 

Some words of advice: slow down and remember that your group members are just as new at this as you are. Learning to be a member of the group, rather than a competing individual in the learning process is a new experience for nearly everyone in this class. Second, this should be seen as a professional experience, not a time for making social contacts. It does not matter whether or not your group mates are the kind of people you would most likely choose to socialize with on Friday night. You will find that you can still work with these individuals.

  Finally, remember that in group work we expect all group members to take responsibility for keeping all of their group mates up to speed and to take personal responsibility for contributing their maximum effort. "The whole is greater than the sum of its parts" is especially true when working in groups. "My group can't get along." Very rarely do we find a group that actually cannot work. What we do find are groups with members who are not communicating effectively. If you think your group is having problems, sit down and talk things over as a group. Agree on some basic rules of conduct and responsibility within your group, and make a commitment to each other. Then try again. If you find you are still having problems, you may need help from someone with an "outside" perspective. Make an appointment when your entire group can meet with your Graduate Instructor, course supervisor, or professor to talk things over. Don't let problems linger or fester, but do try to work things out among yourselves first. Most of all, relax and enjoy interacting with new people. Think of this as preparation for the "real" world where you will be required to work closely with people in many different settings. You will not always like all of those people, but you may find that you enjoy interacting with people who are very different from yourself. Relax, enjoy yourself, and have fun exploring the world around you.

 

Working as a team

Working as a team requires that different members assume different responsibilities. There are many ways to divide responsibility of work in a project and one suggested way is to assign roles, which rotate among group members from week-to-week.

 

Manager

Technician

Quality Control Officer

Safety Officer

 

While each member of the group helps with the lab work, each individual accepts the major responsibility for ensuring that a portion of the project is done properly. Even though the data and the design of the experiment(s) are done collectively, each individual will write a separate lab report. The lab report should not exceed three pages. (excluding the data and graphs and questions from the assigned lab)

Laboratory Reports

You will be working in teams of 2-3 for all of the laboratory experiments (unless otherwise stated). Each individual will submit a single laboratory report for each experiment. While we encourage you to discuss concepts with other members of your class, each written laboratory report must represent the unique effort of each team. All laboratory reports must be typed. All graphs should be generated using a spreadsheet program such as Microsoft Excel.
