The document provides an agenda for a library day to research a problem solution essay. Students are instructed to find four sources to support their essay, with three needing to be highly credible and one with doubtful credibility. A blend of sources supporting the defined problem and proposed solution is recommended. Guidance is given on evaluating source credibility, such as author reputation, timeliness, and bias. Students are assigned to research four sources, read the articles, post a tentative works cited page, and bring their sources and draft to class along with studying vocabulary words.
