Day 29 (WC)

Lesson 12: Sources and Search Engines


This lesson encourages students to think more critically about how web searches work and how to find relevant and trustworthy information online. After viewing and discussion a video about how search engines work, students will search for information about several unlikely animals. They’ll need to analyze the sites they find for reliability in order to identify which of the animals is actually a hoax.


Students will be able to:

  • Use basic web searching techniques to find relevant information online
  • Identify elements that contribute to a website’s trustworthiness or untrustworthiness


  • Algorithm – A precise sequence of instructions for processes that can be executed by a computer
  • Relevant – Closely connected or appropriate to the matter at hand
  • Search Engine – A program that searches for and identifies items in a database that correspond to keywords or characters specified by the user, used especially for finding particular sites on the World Wide Web.
  • Trustworthy – Able to be relied on as honest or truthful
