Sample Lab Report #2

Many of your Science units will require you to write a formal laboratory report. The purpose is to report on what you did, what you learned from an experiment and why the findings matter. Please note lab report procedure many units require students to record notes and observations in logbooks in the laboratory.

These have their own purpose and conventions and are different from lab reports. Lab reports can vary in length and format. These range from a form to fill in and submit before leaving the lab, to a formal written report.

However, they all usually follow a similar basic structure. Figures often include error bars where applicable discusses how results were analysed, including error analysis. Click on the links below to find out more about the different sections of a lab report. Your title needs to reflect the purpose of the experiment. Check with your demonstrator or lecturer for specific requirements. An abstract provides a brief overview of the experiment, including its findings and conclusions.

In general the abstract should answer six questions:. The most important thing to remember when writing the abstract is to be brief and state only what is relevant.

No extraneous information should be included. It also must be clear enough so someone who is unfamiliar with your experiment could understand why you did what you did, and the conclusions you reached, without needing to read the rest of the report. An abstract should be written lab report procedure even though it appears as the first section in your reportlab report procedure it summarises information from all the other sections of the report.

The method section is where you describe what you actually did, lab report procedure. It includes the procedure that was followed. This should be a report of what lab report procedure actually did, not just what was planned. A typical procedure usually includes:.

If any aspects of the experimental procedure were likely to contribute systematic error to the data and results, point this out in sufficient detail in this section. Your description of the experimental set-up should be sufficient to allow someone else to replicate the experiment themselves. When you carry out an experiment, lab report procedure, you usually follow a set of instructions such as these, lab report procedure, which may include extra information to guide you through the steps.

A burette was clamped to a retort stand and filled with standardised NaOH aq and the initial measurement was recorded. The conical flask was placed below the burette, on top of a piece of white paper. Five drops lab report procedure universal indicator solution were added to the flask When writing up the procedure, you must report what was actually done and what actually happened, and omit any extra information such as helpful hints included in the instructions.

Your goal for this section should be to include enough detail for someone else to replicate what you did and achieve a similar outcome. You should also explain any modifications to the original process introduced during the experiment. While most science units require that you report in the passive voicesome require the active voice. In the example below, the first person is used lab report procedure. This is accepted in some disciplines, but not others. Check your unit guide or talk to your unit coordinator.

Read samples of student reports below and identify which examples are written in passive voice, and which use active voice. In this section, you present the main data collected during your experiment, lab report procedure. Each key measurement needs to be reported appropriately. Data are often presented in graphs, figures or tables, lab report procedure.

This section often also includes analysis of the raw data, such as calculations. In some disciplines the analysis is presented under its own heading, in others it is included in the results section. An analysis of the errors or uncertainties in the experiment is also usually included in this section. Most numerical data are presented using tables or graphs. These need to be labelled appropriately to clearly indicate what is shown.

Note that in Fig. For most experiments an error analysis is important, and errors should be included in tables and on graphs. Also, lab report procedure, it is always best to draw figures yourself if you can. If you do use figures from another source, indicate in the citation whether you have modified it in any way.

When showing calculations, lab report procedure, it is usual to show the general equation, and one worked example. Where a calculation is repeated many times, the additional detail is usually included in an appendix, lab report procedure. Check the requirements given in your unit guide or lab manual, or ask your tutor if you are unsure where to place calculations.

Lab report procedure some schools, like Biology, calculations that are too detailed to go into the main body of the report can be added in an appendix. The purpose of such appendices is to present the data gathered and demonstrate the level of accuracy obtained.

A chromatogram was produced for the unknown compound U, and each of the known compounds, lab report procedure, A-E. Rf values for each substance are listed in Table 1.

As well as presenting the main findings of your lab report procedure, it is important that you indicate how accurate your results are. Lab report procedure is usually done through determining the level of uncertainty. The sources lab report procedure error that you need to consider will vary between experiments, but you will usually need to factor in both random and systematic errors.

Your error analysis should identify the main causes of uncertainty in your measurements, lab report procedure, note any assumptions, and show how you have calculated any error bars. Check with your demonstrator, tutor or lecturer if you are unsure about how to determine uncertainties or whether error bars are required for your experiment.

Your discussion section should lab report procedure how well you understand what happened in the experiment.

You should:. The discussion example below is from a first-year Biology unit. The aim of this experiment was to identify decomposition rates of leaf breakdown to establish rates of energy transfer.

It was expected that the leaves would show a far higher rate of decomposition in the shore zone, where there are more chances for sediments to rub against them.

However the two zones show no significant difference in leaf breakdown, although these results are non-conclusive due to the limitations of this experiment. The two zones of leaf decomposition were physically too close, and over the incubation period reeds were observed growing close to the limnetic zone, lab report procedure.

This may have negatively affected the accuracy of the results by reducing the differences in habitat at these sites, as seen in other experiments Jones et al. The results also had large standard deviations, lab report procedure, possibly due to these physical constraints or human error in weighing leaves.

Further studies with more diverse zones and precise procedures should be undertaken in order to explore leaf decomposition and lab report procedure of energy transfer more effectively. Drag each description of each component of the Discussion section to its example.

Notice the order in which the components make up a coherent Discussion section. The conclusion section should provide a take-home message summing up what has been learned from the experiment:, lab report procedure.

In brief lab reports, lab report procedure, the conclusion is presented at the end of the discussion, and does not have its own heading. Note that a conclusion should never introduce any new ideas or findings, only give a concise summary of those which have already been presented in lab report procedure report.

Click again to hide the comment. It is quite possible that you may have in-text citations in your lab reports. Typically these will be included in the introduction to establish evidence of background for current theories or topics, lab report procedure.

Your discussion section will often include in-text citations, to show how lab report procedure findings relate to those in the published literature, or to provide evidence-based suggestions or explanations for what you observed. When in-text citations are incorporated into your lab report, you must always have the full citations included in a separate reference list. The reference list is a separate section that comes after your conclusion and before any appendices. Check your lab manual or unit guide to determine which referencing style is preferred.

Carefully follow that referencing style for your in-text references and reference list. You can find examples and information about common referencing styles in the Citing and referencing Library guide.

The following is an example of a reference list based on the in-text citations used in the Introduction and Conclusion sections in this tutorial. Energy Efficiency Reports. Report no. Many of your Science units will require you to write formal laboratory reports.
