You should describe your experimental design, your subjects, materials, and specific procedures used for data collection and analysis. If you need to include any long lists of procedural steps or materials, place them in the Appendices section but refer to them in the text here. Give enough detail so that others can follow or evaluate your procedures. Your introduction doesn’t need to be long, but you may need to organize it into a few paragraphs or with subheadings such as “Research Context” or “Research Aims.” MethodĪ lab report Method section details the steps you took to gather and analyze data. The secondary hypothesis was that plants with low levels of nitrogen would grow taller than plants with no nitrogen. Example: Referring to previous researchīased on the importance of nitrogen for tomato plants, the primary hypothesis was that the plants with the high levels of nitrogen would grow the tallest. Describe relevant previous research on your topic and note how your study may confirm it or expand it, or fill a gap in the research field. Narrow your topic down your specific study focusīegin by providing background information on your research topic and explaining why it’s important in a broad real-world or theoretical context.Start with the broad, general research topic.One way to write your introduction is with a funnel (an inverted triangle) structure: Your lab report introduction should set the scene for your experiment. This study strengthens the importance of nitrogen for tomato plants. In line with expectations and previous findings, the effects of nitrogen levels on plant height were statistically significant. The plants with the highest level of nitrogen fertilizer were the tallest, while the plants with low levels of nitrogen exceeded the control group plants in height. The effects of nitrogen levels on plant height were tested between groups using an ANOVA. All plants were grown from seeds, and heights were measured 50 days into the experiment. The control group did not receive any nitrogen fertilizer, while one experimental group received low levels of nitrogen fertilizer, and a second experimental group received high levels of nitrogen fertilizer. Levels of nitrogen fertilizer were varied between three groups of tomato plants. It was expected that higher levels of nitrogen fertilizer would yield taller tomato plants. This experiment tested whether nitrogen levels affected tomato plant height in a controlled setting. Tomatoes, one of the most consumed fruits worldwide, rely on nitrogen for healthy leaves and stems to grow fruit. Nitrogen is a necessary nutrient for high quality plants.

Your title provides the first impression of your lab report – effective titles communicate the topic and/or the findings of your study in specific terms.Ĭreate a title that directly conveys the main focus or purpose of your study. If you’re not sure, it’s best to check your lab report requirements with your instructor. For example, some lab reports contain a brief section on research aims instead of an introduction, and a separate conclusion is not always required. Appendices: contains lengthy materials, procedures, tables or figuresĪlthough most lab reports contain these sections, some sections can be omitted or combined with others.References: list of all sources cited using a specific style (e.g.Conclusion: sums up the main findings of your experiment.
Discussion: interprets and evaluates results and identifies limitations.Results: reports all descriptive and inferential statistical analyses.Method: describes the materials and procedures used in the experiment.Introduction: establishes the context needed to understand the topic.Abstract: summarizes your research aims, methods, results, and conclusions.Title: expresses the topic of your study.The sections of a lab report can vary between scientific fields and course requirements, but they usually contain the purpose, methods, and findings of a lab experiment.Įach section of a lab report has its own purpose.
