The following general guidelines must be followed for each lab report The purpose of writing formal lab reports is for you to learn how to write compile proper scientific reports. Each scientific journal has its own formatting requirements; however, they all follow a similar format with a Title, a list of authors, an Abstract or Summary, Materials and Methods, Results (data in tables, figures, pictures and description), a Discussion which interprets results, and a list of References cited in the body of the manuscript. It is suggested that you look through a few journals examples of scientific publications. Some suggested journals are: Plant Physiology, Proceedings of the National Academy of Sciences(PNAS), Nature, and Cell Remember that the lab reports are an opportunity for you to practice your written communication skills. Additionally, it is a great opportunity for you to demonstrate your knowledge of laboratory concepts GENERAL GUIDELINES 1. Double-spaced text and a 12-point font size. One inch margins. m is unacceptable Rather 2. Do not use personal pronouns, i.e,I isolated the chlorophyl use " chlorophyll was isolated by 3. Write in the past tense 4. Each lab report will contain multiple exercises. Combine these into one unit. Therefore you should have one Title, Introduction, Materials and Methods sections, results and discussion 5. Write clearly and concisely using proper grammar, spelling and punctuation. The report should follow in a logical manner making it easy to read TITLE PAGE A cover page which includes a title, your name and identification number, your lab partner s name, the course number, your group number SUMMARY/ABSTRACT A summary paragraph which clearly states the background, results with methods to obtain those results and a conclusion This section is often written last. a basic method to construct the abstract is to summarize each of the sections(Introduction, Materials and Methods, Results and Discussion)into 1 to 2 sentences each NTRODUCTION emainder of the report. Additionally, the Introduction presents the objectives of the study ented in the The introduction presents a background to the research that is presented in the that was conducted MATERIALS AND METHODS In this course, we are not requiring you to rewrite the materials and methods presented in the Course Manual.
