This lesson teaches 4th grade students how to evaluate the reliability of websites by using a 5 W formula: who wrote it, what is it about, when was it made, where did the information come from, and why should it be used. Students will apply the 5 W evaluation to websites on endangered species. The goal is for students to have the foundation to begin online research and know how to assess the quality of sources. By completing a worksheet, students will practice evaluating websites based on the answers to the 5 W questions.
