In this lesson, students will conduct a close read of the article, "Why Teenagers Really do Need an Extra Hour in Bed" by Russell Foster (published on April 22, 2013 in Issue 2913 of NewScientist). For the first reading, students will focus on academic vocabulary. In the second reading, students will answer text-dependent questions to guide their comprehension of the article. In the third close reading, students will choose important facts in the article and cross-reference them with other articles to determine the validity and reliability of the evidence. Graphic organizers and worksheets, along with suggested keys and a writing rubric, have been provided. For the summative assessment, students will write a persuasive letter in which they make a claim regarding sleep and support it with textual evidence.
