When you're clear on what to look for, skim through, pulling out details to fill your graphic organizer. Let's use the first example prompt to illustrate a relevant fact versus an irrelevant one: compare the two scientists' views on the effects of pollution. For this, the focus needs to be on details related to pollution only. Any unrelated details will not be necessary for your comparison. So, a relevant detail would be a statistic on how car pollution diminishes the ozone layer. On the other hand, the fact that one of the scientists worked for NASA is probably not relevant to the topic of pollution. When finding information, be sure to only include relevant information that pertains to the topic.
