Every Thursday, MSP staff will link a current news article to related teaching resources that connect specific content standards to that event. Articles may be appropriate for students to read directly, or they may serve as background knowledge for teachers and inspiration for subsequent instructional activities. The related middle level, grades 5-8 content standards of the National Science Education Standards are included as well as ideas for turning the news event into an inquiry-based lesson.
