Final answer:
View the source code of a website by right-clicking and selecting 'View Page Source' or using the appropriate keyboard shortcut. Evaluate the site's credibility by considering the producer, checking citations, and asking librarians for guidance.
Step-by-step explanation:
To view the source code of a website, you can right-click on the webpage and select “View Page Source” from the context menu. You can also use keyboard shortcuts: Ctrl+U on Windows/Linux or Cmd+Option+U on MacOS.
In some browsers, this option may be listed under the “Developer” menu at the top of the browser. Viewing the source can give you insight into the underlying HTML, CSS, and JavaScript.
When evaluating the credibility of a website, consider the producer of the content. If the site comes from a scholar, a museum, or a research organization, the material likely has more validity. Check if the information is cited, meaning the source provides information on where it got its data.
Reliable sources will be objective and have their facts cross-checked with other credible sources. Your school library may also list reliable sites as resources. When in doubt, don't hesitate to ask a librarian for help, as they are often available online to assist with such inquiries.
