A lab report is a document that summarizes the aims, methods, results, and conclusions of a laboratory experiment. It is an important tool for communicating the findings of scientific research, and it is often required as part of a class assignment in high school chemistry.
The structure of a lab report typically includes the following sections:
Title: The title should be descriptive and concise, and it should give the reader an idea of what the experiment was about.
Introduction: This section should provide the background information and context for the experiment, including the purpose or objective of the experiment, the hypothesis being tested, and the relevant theories or principles that underlie the experiment.
Materials and Methods: This section should describe the materials and equipment used in the experiment, as well as the steps taken to conduct the experiment. This section should be written in a clear and concise manner, so that the reader can understand exactly what was done.
Results: The results section should present the data collected during the experiment, along with any relevant graphs or tables. This section should be objective and should not include any interpretation of the data.
Discussion: The discussion section should interpret the results of the experiment and explain how they support or contradict the hypothesis. This section should also consider the implications of the results and suggest areas for further research.
Conclusion: The conclusion should summarize the main findings of the experiment and state whether the hypothesis was supported or not.
References: This section should list any sources that were cited in the lab report, following the citation style specified by the instructor.
In addition to these sections, a lab report should also include a title page and a table of contents, if applicable. It should also be carefully proofread for spelling and grammar errors.
Overall, a well-written lab report is an important tool for communicating the results of a scientific experiment and for demonstrating the skills and knowledge of a student in chemistry.

As a chemist, you will no doubt need a tool to help you record the various outcomes and observations of your experiments and research. This function should be fulfilled in the sections Discussions or Analysis sections, which should come right afterwards. The density of the known concentration was calculated using the density of the unknown solid, the density of the unknown liquid, and also the density of the NaCl solution to later identify the identity of the solid, the liquid, and the concentration of %NaCl. As with anything, the first time is always the hardest. Using a top-loading balance, weigh 5 g record the mass to the nearest 0 g of unknown metal using a small plastic weighing boat clean and return the weighing boat for reuse by other sections.
This image illustrates sample high school lab report. There are 23 steps to writing a lab report. For example, this concept could be utilized when mechanical engineers design engines for cars and other vehicles. This image illustrates sample high school lab report. If you are preparing a lab report, it may help to have a template to work from. Use this chemistry lab report sample to learn how to write a lab report for chemistry:. This is true because the percent error was only 1% off which is acceptable by any small calculation that could be rounded.
Include sample calculations when appropriate, which include formulas, equations, etc. Mass of graduated cylinder D 26 g d. The purpose of this lab was to classify given substances into one of the general groups represented on the periodic table. You should also list the materials you used in your lab, including the chemicals and equipment. It is important to know that usually lab reports are written after the lab session is finished.
Volume of NaCl solution D 10 mL b. Therefore, the mass and the volume of the unknown object must be measured beforehand. In the graph, the density was plotted against the concentration and a trend line was then drawn. May cause damage to organs. All rights controlled by their respective owners.
It should probably take up a whole, entire piece of paper. SAMPLE INTRODUCTION AND ANALYSIS Classifying Elements as Metals and Non-Metals Lab Report INTRODUCTION: Matter is present everywhere in the world. Record all data and calculations in the Datasheet. Ensure that the inner walls of the cylinder are free of droplets, otherwise, carefully remove it with a paper towel. This image illustrates sample high school lab report.

The other method is used to find the volume of an irregular shape with a given amount of solid. Chemistry Lab Report Example — Measuring the expansion of freezing water at different precisions Sample of chemistry lab report Below is a sample of chemistry lab report on Exploring the law of conservation of mass. That way it is easier to identify the identity of unknown solids, liquids, and concentration solutions. For the usage of ethanol, the hazards might be Highly flammable liquid and vapor. Procedure and materials Note: THE LAB PROCEDURE AND MATERIALS WHERE TAKEN FROM THE LAB MANUAL. You only need to be able to explain why you got the results that you got, and how would you go around to fix them! What were the laboratory hazards and safety precautions in this experiment? It then narrows down to the specific research question relating to this topic.
Because it is really a summary of the entire research paper, it is often written last. Never discuss anything in the Conclusion. This image illustrates sample high school lab report. Never rely on your memory! The instructions directed the cabbage leaves to be placed in the pot before the water came to a boil. You may use a plastic dropper to carefully add the last few drops of liquid so the lower meniscus sits on the white ring mark on the long narrow neck of the flask. You will learn how to save time and effort by organizing things into paragraphs, sections, lists, bullets, tables, etc as you feel appropriate.

Students have to deal with multiple academic tasks, and writing lab reports lots of them! If the law of mass conservation is true, then the reaction between vinegar and sodium hydroxide would measure the same mass as the initial reactants. Knowing and understanding the law of the conservation of mass may potentially help engineers design more efficient and less fuel dependent engines. What practical applications of density did you learn in this experiment? This includes things like measurements, observations, and any other relevant information. Record the 10 mL volume on the datasheet D. It is important to remember that the reader of your report will not have the same level of knowledge as you do about the subject.
