How to write a lab report introduction with examples
These were determined using the Debye-Sherrer powder camera method of X-ray diffraction. If the flaws result from the experimental design explain how the design might be improved.
This is where you interpret the data and determine whether or not a hypothesis was accepted. Avoid interpreting the results save this for the discussion. Updated January 26, Lab reports are an essential part of all laboratory courses and usually a significant part of your grade.
Conclusion can be very short in most undergraduate laboratories. A good introduction also provides whatever background theory, previous research, or formulas the reader needs to know. Your name and the names of any lab partners.
Lab report introduction example
The report should have a thread of argument linking the prediction in the introduction to the content in the discussion. Title Page: This must indicate what the study is about. The primary job of any scientific Introduction is to establish the purpose for doing the experiment that is to be reported.

Mention implications of your findings if appropriate. It is normally desirably to test as quickly as possible after sampling in order to avoid potential sample contamination.

Materials and Methods takes the reader step by step through the laboratory procedure that the experimenters followed. How well has the theory been illustrated? However, the clinical relevance regarding exercise for maintaining or improving bone mineral density in adult men cannot be determined from existing studies [6,7]. This study therefore investigated the impact of physical activity on the risk of fracture in a population-based cohort of men followed over a y period. Clarification of whether no difference or a significant difference was found the direction of the difference only where significant. If you have been using websites then you may have a problem as they might not provide a reference section for you to copy. Use the past tense when talking about the experiment. M, SD, t, X2, F, p, d.
