Final answer:
To write the introduction for a lab report, find background information in peer-reviewed articles, textbooks, and databases, ensuring sources are credible by checking author credentials and citations. The introduction should explain the rationale of the study and state the research question, including proper citations.
Step-by-step explanation:
When drafting the introduction of a science lab report, background information can typically be found in scholarly articles, textbooks, and reputable online databases. To ensure the information is believable, one should look for peer-reviewed journal articles or books published by reputable publishers. Scholarly databases like PubMed or Web of Science are excellent sources for finding credible scientific studies. When reviewing information, check the credentials of the authors and verify that the findings have been cited by other researchers, which adds to the credibility of the work.
Incorporating this background information, the introduction should then provide the rationale for the study, justify the research conducted, and indicate how it contributes to the field. A clear reference to the hypothesis or research question that will be addressed, typically at the end of the introduction, guides the reader into the main content of the report. Proper citation of sources is critical to avoid plagiarism and to acknowledge the original work of others.
