This is my second year doing this activity and I have absolutely fallen in love with it. I used a pre-reading activity to give the kids a good background knowledge of the basics of oil spills. There were multiple resources available on TeachersPayTeachers as well as national articles on the Exxon Valdez and more recent Santa Barbara Oil Spill. A venn diagram activity on the worksheet for your students to do a pre-reading activity comparing two different texts. This fits so nicely with any language arts standards of comparing across texts. Here is the link to the temporary freebie. I hope you enjoy this activity with your kids!!
