Hi, I'm Jim Shields for About.com, and today I'm going to teach you how to write a biology lab report. When you do a biology lab, you're testing a hypothesis to see if it is true. At the end, you're going to have an answer to your question. The point of a biology lab report is to communicate the results of your lab, in other words, to share the answers you got with other people. There are five parts to a good lab report: the introduction, the methods and materials, the results, the conclusion and discussion, and the references. The introduction will explain the purpose of your lab experiment, and it includes the hypothesis you will test. This will give your reader an idea of what you were trying to find out and how you chose to test it.The second part of your lab report is your methods and materials. Now this is more than simply a list of equipment you're going to use, it's how you are going to conduct the experiment. So describe the purpose of all materials and each piece of equipment. Then, write the procedure as thoroughly and completely as possible. If this section is done correctly, the reader could follow the instructions and replicate the experiment. The third part of your lab report is the results section. In this section, you record all the observations of all data that resulted from your experiment. Include all the charts, tables, photos and other evidence that you gathered. When you're recording observations such as the height, weight, length, time, or temperature, be sure to use numerical values and consistent units of measure.The fourth part of your biology lab report is the discussion and conclusions section. In this section, you get to interpret the data you collected and draw conclusions about your hypothesis. This is also an opportunity to reflect on what surprised you, what next steps you could take, or how to extend your learning on this topic.The final section of your biology lab report is the reference section and this is important to make your report scientifically valid. Include all the references that you used, whether it is a book, website or person.So keep in mind those five sections of a good lab report: the introduction, the methods and materials, the results, your discussion and conclusions and your references. Thanks for watching.
