2. Summarize key findings
The act of summarizing key findings is inextricably linked to the process of writing a conclusion for a laboratory report. The conclusion’s efficacy hinges on its ability to distill the experiment’s most salient results into a concise and easily digestible form. Without an effective summary, the conclusion risks becoming a mere repetition of the data or a disjointed collection of observations, failing to provide a cohesive and meaningful interpretation of the experiment’s outcome. The accurate extraction and presentation of the primary data points serves as the bedrock upon which all subsequent analyses and interpretations are built.
Consider, for example, an experiment investigating the effect of temperature on enzyme activity. The key findings might include the optimal temperature for enzyme activity, the temperatures at which activity significantly decreased, and the overall trend observed across the tested range. Simply presenting the raw data points in the conclusion would be insufficient. Instead, the summary should succinctly state, “Enzyme activity peaked at 37C, with a noticeable decline observed above 45C and below 25C, indicating a temperature-sensitive enzyme function.” This concise summary then allows for a more focused discussion of the underlying mechanisms, potential sources of error, and the broader implications of these temperature sensitivities.
The ability to effectively summarize key findings also demonstrates a deeper understanding of the experiment’s purpose and limitations.

The ability to discern patterns, trends, and relationships within the collected data, and to then contextualize these findings within existing scientific knowledge, forms the essence of this interpretive process. A conclusion devoid of such interpretation lacks substantive value, offering only a superficial account of the experimental outcome.
Consider, for example, a study examining the effect of different fertilizers on crop yield. Raw data might reveal that Fertilizer A resulted in the highest average yield. However, a meaningful conclusion requires interpretation: perhaps Fertilizer A provided the optimal balance of nitrogen, phosphorus, and potassium for the specific crop, or it facilitated superior nutrient uptake due to its unique composition. Conversely, unexpected results, such as a negative correlation between a variable and the outcome, also demand interpretation. Addressing confounding variables or limitations of the experimental design, or explaining the result with potential mechanisms even if not previously hypothesized, are essential to extracting information from the data. The interpretative step should then be placed in the context of similar work, noting if the work supports or contradicts existing studies.
In summary, effective interpretation of results is not merely an adjunct to a conclusion but an integral component. It transforms raw data into meaningful insights, allowing for the development of informed assertions and fostering a deeper understanding of the underlying phenomena.
