How To Write a Report for Work (With Examples)

How to Write a Practical/Laboratory Report Writing Centre Learning Guide The ability to report technical information clearly and concisely is fundamental to the sciences. As such, science students are often required to prepare formal reports about experiments or investigations undertaken in the practical components of their courses. Jan 12,  · How to write a practice report: where to start Writing any practice report begins with receiving a methodological instruction at the university. This is a kind of instruction for writing a practice report. Manuals must be obtained at the department.

Got to document an experiment but don't know how? In this post, we'll guide you step-by-step through how to write a scientific report and provide you with an example. Is your teacher expecting you to write an experimental report for every class experiment? Are you still unsure about how to write a scientific report properly? We will guide you through all the parts of a scientific report, step-by-step.

Scientific reports allow their readers to understand the experiment without doing it themselves. In addition, how to prevent foodborne illness at home reports give others the opportunity to check the methodology of the experiment to ensure the validity of the results.

A scientific report is written in several stages. We write the introduction, aim, and hypothesis before performing the experiment, record the results during the experiment, and complete the what medicine to give a toddler for a cold and conclusions after the experiment.

But, before we delve deeper into how to write a scientific report, we need to have a science experiment to write about! Photosynthesis is a vital process for life. It occurs when plants intake carbon dioxide, water, and light, and results in the production of glucose and water. The light required for photosynthesis is absorbed by chlorophyll, the green pigment of plants, which is contained in the chloroplasts.

The glucose produced through photosynthesis is stored as starch, which is used as an energy source for the plant and its consumers. The aim identifies what is going to be tested in the experiment. This should be short, concise and clear. The hypothesis is a prediction of the outcome of the experiment. You have to use background information to make an educated prediction. It is predicted that photosynthesis will occur only in leaves that are exposed to light and not in leaves that are not exposed to light.

This will be indicated by the presence or absence of starch in the leaves. Identify the hazards associated with the experiment and provide a method to prevent or minimise the risks. A hazard is something that can cause harm, and the risk is the likelihood that harm will occur from the hazard.

Remember, you have to specify the type of harm that can occur because of the hazard. It is not enough to simply identify the hazard. Wear closed, durable shoes to prevent injury from falling sharp instruments. Methylated spirits are highly flammable and can cause burns or fires. Low Before using methylated spirits, ensure that all ignition sources such as Bunsen burners and matches are extinguished.

Minimise the volume of methylated spirits used. The rule of thumb is that you should write the method in a clear way so that readers are able to repeat the experiment and get similar results.

Using a numbered list for the steps of your experimental procedure is much clearer than writing a whole paragraph of text.

The steps should:. You also need to use past tense and passive voice when you are writing your method. Scientific reports are supposed to show the readers what you did in the experiment, not what you will do.

After you finish your steps, it is time to draw your scientific diagrams! Here are some rules for drawing scientific diagrams:. This is where you document the results of your experiment. Qualitative data is data that relates to qualities and is based on observations qualitative — quality.

This type of data is descriptive and is recorded in words. For example, the colour changed from green to orange, or the liquid became hot. Quantitative data refers to numerical data quantitative — quantity. This type of data is recorded using numbers and is either measured or counted. For example, the plant grew 5. You also need to record your results in an appropriate way. Most of the time, a table is the best way to do this. The discussion is where you analyse and interpret your results, and identify any experimental errors or possible areas of improvements.

That is, the relationship you observed between your independent and dependent variables. The independent variable is the variable that you are changing in the experiment. In this experiment, it is the amount of light that the leaves are exposed to. The dependent variable is the variable that you are measuring in the experiment, In this experiment, it is the presence of starch in the leaves. Explain how a particular result is achieved by referring to scientific knowledge, theories and any other scientific resources you find.

Scientific explanation:. The presence of starch is indicated when the addition of iodine causes the leaf to turn dark purple. The results show that starch was present in the leaves that were exposed to light, while the leaves that were not exposed to light did not contain starch. Provide an explanation of the results using scientific knowledge, theories and any other scientific resources you find.

As starch is produced during photosynthesis, these results show that light plays a key role in photosynthesis. Validity refers to whether or not your results are valid. This can be done by examining your variables. Identify the independent, dependent, controlled variables and the control experiment if you have one. The controlled variables are the variables that you keep the same across all tests e. It is untouched for the whole experiment. The independent variable of the experiment was amount of light that the leaves were exposed to the covered and uncovered geranium leafwhile the dependent variable was the presence of starch.

The controlled variables were the size of the leaf sample, how to pin a post on facebook duration of the experiment, the amount of time the solutions were heated, and the amount of iodine solution used.

Show that you repeated your experiments, cross-checked your results with other groups or collated your results with the class. The reliability of the results was ensured by repeating the experiment 5 times and comparing results with other groups. Since other groups obtained comparable results, the results are reliable.

Accuracy should be discussed if your results are in the form of quantitative data, and there is an accepted value for the result. Accuracy would not be discussed for our example photosynthesis experiment as qualitative data was collected, however it would if we were measuring gravity using a pendulum:. The measured value of gravity was 9. Possible improvements how to set cruise control on toyota corolla be made by including control experiments.

For example, testing whether the iodine solution turns dark purple when added to water or methylated spirits. This would help to ensure that the purple colour observed in the experiments is due to the presence of starch in the leaves rather than impurities.

The aim of the investigation was achieved, and it was found that light is required for photosynthesis to occur. This was evidenced by the presence of starch in leaves that had been exposed to light, and the absence of starch in leaves that had been unexposed. These results support the proposed hypothesis. Use the scissors correctly and store them after use. Before using methylated spirits, ensure that all ignition sources such as Bunsen burners and matches are extinguished.

Writing effective work reports takes practice and requires good communication more reports you write, the more efficient you will be in composing them. The following are steps you can take to write a professional report in the workplace. The way to write a Prac. Report is- 1. Title 2. Aim 3. Materials 4. risks 5. Method 6. Results 7. Discussion and/or Observation (I don't think it matters which way you put these) 8. Conclusion.

Yacoubb Guest. The general template for a practical report should be followed and this will probably be the best way to achieve good SAC scores. Title: the title may be given to you, however, if you are not given a title, make sure the title you come up with is applicable and appropriate to the prac you are completing. Name: Your name. Date: date which you do the prac. Due Date: the date which the prac is due this will be the same as due date for a SAC.

Aim: Your aim is what you are investigating. For example, let's use the example of osmosis in potato cells. The aim of the experiment was to observe the osmotic activity of water molecules into and out of a potato cell when placed in different solutions. You basically propose what you are going to observe , evaluate , interpret or analyse. Hence, the underlined words can actually be used in your aim.

Hypothesis: This is your educated guess about the outcome of the investigation. This should not contain any quantitative values because it is merely a 'guess'. Ensure you do not confuse this with the aim, particularly in exam questions where you must outline and design an experimental.

So let's make a hypothesis using the osmosis prac: - Water will move out of the potato cell when placed in a hypertonic solution. You are guessing the outcomes of the experiment. Hence, an educated guess. You need to make a reference to the "attached sheet", or perhaps state the page number if it is found in a book.

Method: This should be in a sequential order. The potato cell was left in the solution for 20 mins. Note how each step is clear, concise and to the point. No superfluous info. Observations: This is a qualitative description; this can include potential problems encountered e.

No numerical or quantitative values should be described here. You will be asked a series of questions for which it will be important you list the answers in dot point form. Hope this helped and good luck!! For some reason I just can't seem to get full marks.. Has got extra shortcut formulas which you can get nowhere else, and includes vital watchouts for the exam!

Bad Student Guest. Is it necessary to have an introduction before your aim? I always included one when I wrote prac reports last year. Quote from: Bad Student on February 11, , pm. Your a lifesaver Yacoubb! I must ask though, In what section do you write about the variables and in what manner?

Quote from: k-dog on February 12, , pm. Sc UniMelb Neuroscience Major ?? Its alright. Look variables are often in your results section and not explicitely stated. I mean, the independent variable in the experiment used in example would be the solution the potato cell is placed in.

This would be elaborated upon in perhaps your discussion where you describe the results you obtain by placing the potato cell in varied solutions. I hope this helped!!

How long should a discussion be? By answering the questions, error analysis and general discussion of results i could probably get a page, is this enough? Oh and at my school they teach us to do intorductions that replace the aim, hypothesis etc and include theory behind prac, so that is why my discussion might not be as long as i put a lot of theory into the intro.
