Abstract

To make laboratory work more meaningful it is advisable to follow certain basic guidelines. Before starting an experiment read carefully the protocol, the assigned objective and the hypothesis involved. Then prepare the plan of work before actually starting the experiment. Do not be a "filter paper scientist". Record all primary operations and data directly in your bound notebook. Data recorded in discs of filter paper on loose sheets of paper are likely to get lost. Data should be recorded in tabular form in well-defined format. All the data obtained should be recorded in your report no matter how unsatisfactory the data may appear to be. Do not feel perturbed if data, negative to your expectation, are obtained. Negative data are more meaningful and pave the way for exploration of protocol and testing of other components. It also provides opportunity to indicate the loopholes in your experimentation. Graphical presentation of data should be done in order to quicker understanding of the experimental results. Finally, a concise report should be presented stating the methodology, results obtained and a brief discussion about the findings. At the end of day, your working bench should be as clean as it was in the beginning of the experimental operations.
