The Probability of Human Impact

Students will explore the mathematical concept of probability in the context of marine debris in the ocean. Using a spinner with items an animal could potentially ingest, students calculate the probability that the animal will encounter marine debris instead of food. By altering the spinner, they can see impacts that increased or decreased amounts of marine debris in the system could have on marine animals. This activity is available for Grades 4-5, within the "Impacts" unit. 

Oregon Sea Grant at Oregon State University created a comprehensive, web-based, Marine Debris Science, Technology, Engineering, Art, Math, and Social Studies (STEAMSS) Curriculum with support from the NOAA Marine Debris Program. Marine Debris is a complex, real-world problem which can be addressed through the lenses of several different academic subjects. This curriculum integrates the subject areas of STEAMSS, focusing on experiential hands-on activities for students. The collected teacher-tested resources enable educators to create in-depth, project based learning (PBL) units, work with teaching partners across disciplines, and find classroom and field experiences that will help students explore the issue and impacts of marine debris and engage in stewardship actions. With this curriculum students collect and analyze data, address problems through engineering design, use technology and art to effectively convey stewardship messages, contribute to clean up efforts, and work with community partners.
