This collection of activities is based on a weekly series of space science mathematics problems distributed during the 2012-2013 school year. They were intended for students looking for additional challenges in the math and physical science... (View More) curriculum in grades 5 through 12. The problems were created to be authentic glimpses of modern science and engineering issues, often involving actual research data. The problems were designed to be one-pagers with a Teacher’s Guide and Answer Key as a second page. (View Less)

Students will learn about black holes through reading a NASA press release and viewing a NASA eClips video segment. Then students will use tables and mathematical expressions to compare black hole sizes and temperatures. Common Core State Standards... (View More) for Mathematics and English Language Arts are identified. This activity is part of the Space Math multi-media modules that integrate NASA press releases, NASA archival video, and mathematics problems targeted at specific math standards commonly encountered in middle school textbooks. The modules cover specific math topics at multiple levels of difficulty with real-world data and use the 5E instructional sequence. (View Less)
